✅ Ariston dishwasher malfunctions: 6 main causes of breakdown

The main causes of breakdowns of the Hotpoint Ariston dishwasher

It is always better to find out the cause of equipment failure yourself. This will be useful for home repairs and when calling for service. This way you will know that the masters are not imposing unnecessary expenses on you.

The location of the breakdown can be determined by external signs and malfunctions of the machine. Also, the equipment itself can report a malfunction by highlighting a code on the display. If your control panel has a screen, then the code will appear as a combination of letters and numbers. A panel without a display will indicate a problem by flashing indicators.

Here are the main error codes:

AL01 (indicator 1 or 3 lights up) - the “Aquastop” leakage protection is turned on;
AL02 (2-4) - water does not enter the hopper;
AL03 (1-2/3-4) - waste liquid does not leave the tank;
AL05 (1-3/3-5) - problems with the operation of the circulation pump or pressure switch;
AL10 (2-4/4-6) - heating element circuit malfunction.

The meaning of the code on your display can be found in your instruction manual. If you want to know what to do, take a look at our Ariston Dishwasher Error Codes page.

PMM "Hotpoint Ariston" is similar in structure to Electrolux machines. Their malfunctions can be repeated, but still the following breakdowns are more common in Ariston models:

The heating element does not work . This reduces the quality of washing; the cycle is carried out in cold water. If the heater penetrates the housing, the plugs may be knocked out when the PMM is turned on.
The machine does not take in water . You may hear a hum, but no fluid is entering the tank. The cause could be blockages in the intake tract or a malfunction of the intake valve.
The water intake does not turn off, while the drain is constantly running . Damage to the fill valve or level sensor.
During operation, noise and hum are heard . The issue may be a blockage, a problem with the engine or its bearing.
Leak in the car. The worst case scenario is case corrosion. At best, wear of gaskets and seals.

Water does not drain . The drain, filter, hose or sewer is clogged. Drainage pump failure.

These are the problems users encounter. Let's figure out how to eliminate them.

Ariston dishwasher errors

Washing dishes is a tedious process that Ariston dishwashers can perform. The equipment of this brand is becoming very popular due to its good combination of quality and price. Any mechanism can break down. Errors occur in Ariston dishwashers, which the self-diagnosis system helps to recognize; below are the error codes and the actions that must be taken to eliminate them.

Hotpoint-Ariston dishwashers

Ariston dishwashing equipment is represented by a wide range. The consumer has the opportunity to choose the model that, in his opinion, best meets his needs. The difference between the models lies in size, as well as performance and economy.

Ariston has many advantages:

Takes up little space in the kitchen.
Relatively low noise level during operation, thanks to the function of effective absorption of noise emitted by mechanisms during operation.
The spacious basket allows you to load a large amount of dirty dishes.
It may not be fully loaded.
Possibility to load during the wash cycle.
Self-cleaning filters ensure that dishes are washed only with clean water.
Protection against leaks, that is, the equipment is provided with an electronic protection system that blocks the water supply.
Economical water consumption.

Hotpoint-Ariston dishwasher with screen

Hotpoint-Ariston dishwashers are equipped with a self-diagnosis system. This system helps to recognize a malfunction and remove it in time, preventing serious damage. All Ariston dishwasher errors have their own code.

Problems with water heating

Problems with water heating in Ariston dishwashers are indicated by error code AL10 . If this problem occurs, the LED light will blink:

for a 4-program device 2 – 4 times;
for a 6-program 4 – 6 times.

Reasons why errors in Ariston dishwashers are possible:

heating element burned out,
the control module is faulty,
Damage may be in the wiring or electrical circuit.

Error code A 05 for a water heating problem indicates that the signal from the heating element sensor is not being received.

Problems with draining and filling water Hotpoint-Ariston

If there are interruptions in the water supply, it is initially better to check its availability in the water supply network. Sometimes, due to low pressure, water does not flow into the machine. It is also worth checking the water filter, which is installed before entering the car. Very often it becomes clogged with rust from old pipes.

Problems with draining (sometimes the waste liquid is not all drained) may be due to the drain hose being raised too high.

Ariston dishwashers may have errors with the water fill function. This failure is indicated by code AL02 :

in sinks where 4 programs are installed, the light flashes 2 times;
in devices with 6 programs installed, the light flashes 4 times.

In this case, you need to check the SV fill valve.

When error code AL03 :

4 software devices blink 1-2 times;
for 6 software programs – 3-4 times.

In this case, the water will not drain.

If the permissible time for draining the Hotpoint-Ariston dishwasher is above 4 minutes. And the sensor indicating the water level indicates the “full” state, then it is possible:

The drain pump is clogged or faulty. In this case, you need to remove the filter and clean it and rinse it under running water.
The wire has broken or there is no contact.
The reason may lie in the blocking of the pump impeller.
The electronic module has failed. In this case, replacement with a new module is required.

If the pump is being cleaned, the contacts and integrity of the windings are simultaneously checked.

Error code A 14 of the Hotpoint-Ariston dishwasher may indicate that the drain hose is not connected correctly.

Problems due to blockages

Very often problems with Ariston dishwashers malfunctioning are clogs. That is, the drain hose may become clogged if there is a problem with the drain. The code in this case will be A 03. To eliminate this problem, check the drain pump, drain hoses and filter for blockages.

The main causes of breakdowns of the Ariston dishwasher

There may be several reasons why the dishwasher is not working. As mentioned above, you need to pay attention to the “symptoms” of a breakdown. Let's take a closer look:

PMM Ariston does not heat water. The cause may be a broken heating element. You should check the wiring leading to the heating element, the heater itself and the thermostat. The latter helps measure the water temperature, so if it breaks, it needs to be replaced.

When the machine does not draw water, you need to check the presence of water in the water supply. Sometimes the reason is a clogged inlet hose or mesh filter. Have you noticed that your dishwasher doesn't wash dishes well? Check the nozzles on the sprinkler, they may be clogged.
Water constantly fills and drains in the dishwasher. This malfunction indicates problems with the fill valve. Its membrane does not close, so water constantly flows, while the indicator flashes, notifying you of a breakdown. The reason may be the level sensor, which is responsible for monitoring the water in the tank.

The machine makes noise when operating and the water does not drain. The rocker arms could be clogged, or the pump could be broken.
The cause of the machine leak could be the drain and inlet hose. Depressurization of the housing or door could also cause water leakage. A thorough inspection and replacement of parts is required.

Your Ariston dishwasher won't start or turn on? Connect another device to its socket. If it doesn't work, then the socket is faulty. Next, check the onboard switch. Ring the contacts of the switch; if faulty, replace it.

If your car is still under warranty, then you should not solve the problems yourself. It is better to contact a service center.

Do-it-yourself Ariston dishwasher repair

Gone are the days when dishwashers were a rarity.
Accordingly, their repair services are also gaining momentum. We think you will be interested in how to save on breakdowns and not call a repairman. How to repair an Ariston dishwasher with your own hands will be discussed in our article.

Options may be available on BIT100 and DIWA boards.

Moreover, this could be Ariston and Indesit dishwashers.

How to repair a dishwasher

In some cases, you can fix the problem yourself. Before starting work, disconnect the Ariston machine from the network and communications. Prepare the necessary tools.

Heater replacement

The heating element often suffers from scale when using hard water. If you hear an unpleasant burning smell, you need to check the wiring of the heating element, which may have burned out. Are you sure that the Hotpoint-Ariston heater is faulty? Then start replacing:

Open the hatch door where the dishes are loaded.
Remove all trays and shelves.
Remove the water spray by pulling it up. It is located at the bottom of the car.
At the bottom there is a filter that protects the pump from contamination. Unscrew the part and remove the mesh from below.
Unscrew the bolts that secure the pipe and the heater.
Place the dishwasher on its side with the bottom exposed.
If the machine is freestanding, remove the rear panel by unscrewing the mounting bolts. If the device is built-in, remove the bottom.
A pump is attached to the side of the heating element. You need to unscrew it clockwise. Disconnect the pump wiring and remove it from the housing.
Disconnect the rubber fastener of the heater and remove the heating element.

Tip: To ensure proper wiring, take a photo of the connectors before removing the item from its socket.

Start the machine after repair to check the operation of the new element.

Checking the water intake valve and level sensor

When water does not flow into the Ariston dishwasher or, on the contrary, it constantly fills, check the intake valve. The part cannot be repaired, so you will need to disassemble the PMM:

Remove the side or back panel (depending on model) of the dishwasher.
The valve is located immediately behind the inlet hose.
Unscrew the valve fasteners and disconnect the wiring.

For replacement, a part is selected for a specific dishwasher model.

The pressure switch could also be broken. The reasons for its breakdown are natural wear, burnt contacts, and blockages in the pressure tube.

How to disassemble the car and get to the sensor:

Open the bottom of the dishwasher.
Find the level sensor. It looks like a box with pipes.
Unscrew the two mounting bolts.
Remove the tube from the box using pliers.
Inspect the tank (box) for pressure.
Check the electrical part of the pressure switch by measuring the resistance at the contacts.
If damaged, install the new part in reverse order.

It’s easy to make the replacement yourself. Be careful and follow the recommendations.

Pump replacement

Below are instructions for replacing the dishwasher drain pump. The main thing in this repair is to properly disassemble the dishwasher.

Open the machine's hopper door.
Empty the hopper of shelves and baskets.
Pull out the bottom filter, as well as the metal mesh.
Unscrew the inlet hose.
With the machine on its back, remove the bottom cover. To do this, unscrew the screws around the perimeter.

Disconnect the wiring connectors from the pump.
Use pliers to loosen the clamp on the drain hose. Disconnect it from the pump.
Unscrew the fastening screw and remove the pump assembly.
Reinstall the new pump with the rubber seal. Connect the wiring.

What to do if the dishwasher does not work - DIY repairs

A dishwasher is not as complicated a piece of equipment as it seems at first glance. Most breakdowns are caused by simple reasons. Eliminating them does not require high qualifications or special knowledge. If the equipment is no longer under warranty, you can try to repair it yourself. We will describe the main malfunctions of dishwashers and how to eliminate them further. In most cases, the causes and methods of elimination do not depend on the brand of the machine. Bosch, Siemens, Samsung, Electrolux, Miele, Indesit, Candy, Beko - it doesn’t matter. The repair is the same. The disassembly process, fastening, etc. may differ. But the basic principles of finding the causes and troubleshooting dishwashers are the same.

A dishwasher is every housewife's dream

DIY Ariston dishwasher repair, error codes

Like any complex equipment, Ariston dishwashers can sometimes experience malfunctions and malfunctions. Some problems can be solved quite simply, but to fix others you will need either certain skills and experience working with equipment, or you will have to contact service specialists.

Is it possible to imagine a modern kitchen without a dishwasher? Happy owners of such equipment no longer want to give it up. And any person who does not have a dishwasher, but has at least once seen how good the result of its work with dishes is, begins to think that he is missing something. And somehow he begins to be drawn to the store. And there is an abundance for every taste and budget.

Dishwashers from the Italian brand Hotpoint-Ariston are quite in demand. And it’s no coincidence. The products of this manufacturer invariably have excellent characteristics and functionality.

Ariston dishwashers are available in compact, medium and full-size formats. Can fit into any kitchen. And with all this, they are sold at an adequate price. No wonder they are very popular.

How does a dishwasher work?

To repair a dishwasher, you need to understand the processes that occur in it. This is the only way to determine the possible causes of the breakdown and eliminate them as soon as possible.

Let us describe the general principle of operation of a dishwasher. The operating algorithm is usually the same for all manufacturers, although some changes may occur. Next, we will describe the most time-consuming process - washing dirty dishes with time to “acidify” the remaining food.

After loading the dishes, the door closes. This is recorded by a special sensor. If the lock is not closed, the dishwasher will not start.
The user selects the dishwasher operating mode and presses the “Start” button.

Rinse water is supplied from all sides

Water is supplied from the nozzles under pressure

As you can see, a large number of sensors are involved in the process. All of them can fail and cause a breakdown. Filters, nozzles, and sprinklers may also become clogged. All these are causes of failure.

Breakdowns, possible causes, elimination

Many dishwasher breakdowns can be resolved with simple steps. Often problems are associated with low voltage in the electrical network or low pressure in the water supply. Many breakdowns are explained by the fact that filters, grilles, and openings are clogged with food debris. All these reasons can be eliminated independently, restoring functionality.

The dishwasher does not draw or drain water - you can figure out the reasons yourself

We check at the very beginning and if the PM does not start working

Many malfunctions of dishwashers are explained by simple reasons - a drop in voltage in the network, insufficient water pressure, clogged filters, etc. At the very beginning, after we have discovered that the dishwasher is not working or is working abnormally, we check:

Voltage - should be 220 V with a slight deviation.
Cord condition. If there are visible problems, check the integrity of the cord.

Problems with the cord - a possible dishwasher malfunction

These are very simple steps, but it is for these reasons that the dishwasher often does not start working.

Water leak

Some dishwasher problems are caused by water leaks. Then the dishwasher stops during operation and no longer responds to commands. One of the combinations also lights up, signaling a breakdown, but each manufacturer and even each model has its own. But the result is the same - during the washing process (no matter at what stage), the car stops and no longer responds to any signals. Sometimes it can be started again. But after turning it on, it stops again.

The fact is that there is a leakage protection sensor in the pan - it is a polystyrene float. When water appears in the pan, it rises and a contact closes, which is perceived as an emergency signal. Everything is logical - if water appears in the pan, then something is going wrong. This float prevents flooding of your apartment and neighbors below.

Here are the possible causes of PMM water leaks:

The dishwasher is not level and water is overflowing over the edge of the reservoir.
Using too much detergent resulted in a lot of foam. Also, do not use a product that is not intended for dishwashers.
The machine takes in too much water - problems with the water level sensor. During the washing process, open the machine door and make sure that water does not overflow. If there is too much, replace the sensor.

Polystyrene float - leakage sensor

Sometimes a water leak in a dishwasher is a result of a leak in one of the parts. Then you need to remove the back wall of the dishwasher and carefully inspect all the parts. There may be a leak in the hose, a connection that has lost its tightness, etc.

No drain

There are malfunctions of dishwashers of the opposite nature - the PM does not drain the water. There are reasons of a different nature. This type of breakdown is often associated with a clogged drain hole or hose. Here's what it could be:

The drain hose is pinched or a waste plug has formed in it.
The drain hole is clogged. Unscrew the protective mesh, pull out the sediment filter, clean it and rinse it of food debris.
The drain is clogged and the water just won't drain.
Residues of food have jammed the pump.

To remove the filter in the dishwasher - you need to know how (you can read the manual), but usually it can be unscrewed

If the problem is a clogged machine, the first step is to clean the drain and filter. Next, remove the pump cover. This is a plastic cover secured with bolts (bolt). In some brands it is secured with latches. We clean the impeller and impellers (holes for spraying water). In general, we remove all residues and dirt that catch our eye. The cleaner the machine is, the less likely it is to have another shutdown.

If you are repairing a dishwasher yourself and have little experience in this matter, take photographs of the position of all parts and pieces before you begin to disassemble the unit. It will be easier to restore everything. Even if it seems like there is nothing to forget.

We install everything in place and turn on the car. The water flow should be restored. If not, the problem may be with the pump. It does not pump water and should be replaced.

No water coming in or not enough water being collected

Dishwasher malfunctions are often water related. And one of them is that you don’t get enough water. It could also be that the detergent is not washed off and does not rinse well. All these dishwasher malfunctions can be caused by one reason - insufficient pressure. It is checked first. The pressure in the system must be above the minimum threshold at which the PM can be operated (found in the passport). If the pressure is normal, there may be the following reasons for this failure:

The faucet on the outlet to the dishwasher broke. Turn off the water, remove the hose, place a container, and turn on the water. Everything is fine - let's move on.
The inlet valve is clogged. Unscrew the hose, remove the filter with pliers or tweezers, clean and rinse the filter.

To check whether the lack of water is really the reason for the shutdown, pour water inside and start the unit

To make sure that the problem is in the water supply system and not in others, pour 4 liters of water into the machine, load some dishes and start it up. If the machine does not clean, there is likely a problem with the dishwasher control.

Doesn't wash well

Sometimes, after some time after you start using it, you notice that the dishwasher does not wash dishes as well. Such malfunctions are usually associated with violation of operating rules, but there may also be technical problems. So, what could be the reasons that the quality of washing dishes has deteriorated:

Insufficient amount of detergent (occurs after purchasing a new detergent).
The dishes are not stacked correctly.
The heating element has burned out, the water is not heating up.
The filter-sump is clogged (the process is described above).

Troubleshooting dishwashers: cleaning the drain and water injection holes is never a bad idea

Dishwasher malfunctions due to deterioration in quality can also be caused by control failures. If you have checked all possible causes and there is no improvement, follow the process. You may be able to figure out why your dishwasher has gotten worse at cleaning dishes.

Knocks out the circuit breaker

Dishwasher malfunctions associated with electrical problems usually appear after power surges. Then the control also crashes. Therefore, during installation, it is advisable to take care of installing a stabilizer. If not general - for the whole apartment or house, then at least local. This could be a low-power unit for connecting a dishwasher, or maybe a more powerful one, to which you can connect several electronically controlled appliances.

Electrical diagram of a dishwasher

If, when you turn on/start the dishwasher, the circuit breaker in the panel is knocked out, the reasons may be the following:

The heating element has burned out.
Short circuit of the wiring inside the PM.
The seal is broken and water gets into the parts.
Voltage fluctuations in the network.

Identifying the exact cause of most of these faults (other than seal failure) assumes that you know how to use a multimeter. Take the electrical diagram of the dishwasher, first check the condition of the fuses, then follow the diagram.

These are, perhaps, all the main malfunctions of dishwashers that you can fix yourself. If these measures do not help, you will have to resort to the services of specialists.

Possible problems with Ariston dishwashers and current methods for correcting them

Let's see what the machine can tell us in different situations. And we will immediately decide what needs to be done. We will designate the signals as follows: code “_”; “_” – number of indicator blinks for a machine with 4 programs; “_” – number of flashes for machines with 6 programs.

Leakage protection has tripped (code AL01; 1 flash; 3 flashes)

It’s worth noting right away that calling this protection the term Aquastop is incorrect. Even if the dishwasher manufacturer himself does this. And for us, copyright is not an empty phrase. The term AquaStop is an entire protection system that includes solenoid valves and sensors.

The name and the system itself are patented and are usually used in washing machines and dishwashers of the Bosch and Siemens brands. We are watching Ariston. In this situation, the leakage protection of the housing, which is a pan with a float, was activated. When a leak occurs, water collects in the pan and the pop-up float blocks its further movement.

We turn off the water supply and disconnect from the network. What is needed to correct the situation? Carefully check all connections through which water circulates and the tightness of the washing chamber. The tube on the circulation pump may have come loose. The pump can be accessed through the bottom of the machine.

Water does not enter the machine (code AL02; 2 flashes; 4 flashes)

According to the manufacturer, you need to immediately check the water inlet valve. There is no reason not to trust a serious company. It’s just better to start with more prosaic things. First, it’s worth clarifying - is there water in the tap? Is its pressure enough? Any dishwasher has a minimum water pressure level at which it can operate normally.

Otherwise, flooding is impossible. Is there water and pressure normal? Then we check the inlet hose along its entire length. There should be no pinches or bends. If there are, they need to be eliminated. If your inlet hose is equipped with a leakage protection valve, check the indicator of this valve.

Sometimes the indicator is the hose itself (it changes color). If the protection is triggered, the valve blocks the water supply directly near the tap. This type of hose has disposable protection and will have to be replaced with another.

It would be a good idea to check the filter mesh at the entrance to the machine. The mesh may well be clogged with rust or other impurities contained in tap water. If this is not the case, then yes, you need to check the water inlet valve. His nutrition may be disrupted. Checking the wires. If necessary, we replace it with a working one.

Ariston dishwasher does not drain water (code AL03; 1-2 flashes; 3-4 flashes)

Failure to drain is almost always due to a problem with the drain pump or water level sensor. The pump may not work (or not work correctly) in several cases:

clogged drain filters,
the pump impeller is blocked,
the pump is faulty (or the wire could simply come loose).

In the first case, if the machine does not drain the water, you need to remove the filters that are located at the bottom of the washing chamber and thoroughly clean them of dirt.

The filters are washed under running water. The sump pump impeller may also be contaminated with food debris or broken dishes. It is necessary to clean it and ensure its unhindered movement. The impeller should rotate without interference.

To check the functionality of the drain pump, you will have to disassemble the lower part of the dishwasher. After removing the base, access to the internal components of the machine opens. When gaining access to the pump, carefully inspect its contacts. Then you need to check the integrity of the windings with a multimeter.

If the pump malfunctions, you will have to replace it with a new one. And the last possible option is a malfunction of the electronic control module. There is no point in trying to repair it. It can only be replaced.

The circulation pump or level sensor is faulty (AL05; 1-3 flashes; 3-5 flashes)

The circulation pump is the main component of the dishwasher, its motor.

To get to it, you will have to disassemble the dishwasher from below (just like when replacing the drain pump). It is necessary to check all the contacts connected to it. If there are breaks, you need to restore the connections. Check the windings.

Disassembling the pump is problematic. Although there are craftsmen who can do this. May need replacement. The level sensor is located in the same part of the machine.

It may also have loose wires or a clogged tube. Most often you will need to replace it with a new one.

Installation instructions

The dishwasher can be free-standing, built into the kitchen furniture (in a set, under the countertop) or, if it is small in size, in a desktop version. In any case, you must follow the first installation rule: the equipment must be level. Leveling will help reduce vibrations during operation and, as a result, movement of the machine. And this already affects the readings of individual sensors, for example, those responsible for the water level.

It is necessary to comply with certain requirements for the installation of household appliances. It is better to place the dishwasher close to the water supply and sewer lines.

The electrical outlet must be located within the length of the power cord and must be grounded. It is necessary to comply with the design of the socket and plug.

User manual

The user manual is a kind of “bridge” between the owner and the equipment itself. If you have a Hotpoint Ariston dishwasher, the operating instructions for this unit in a concise form reflect the main recommendations for using dishwashers (DMM) in everyday life. Before you start using the equipment for its intended purpose, you need to carefully study its features. Any sentence in the instructions carries a specific semantic load; there are no unnecessary words in it. You need to start with a description of the PMM device. Knowing the location and purpose of the components is a necessary condition for using the machine.

Loading baskets with dishes must follow certain rules for the machine to operate efficiently.

Many housewives know that removing food debris from plates and pots is a must.
It is also important to place items in baskets; it should not contribute to the accumulation of water on it. Loading the PMM with dishes should not interfere with the free rotation of the spray nozzles.
The operating modes of the machine also take into account the properties of the materials from which the dishes are made. For example, thermoplastic products should be placed in the upper basket, with a lower temperature.

How to properly use special products during the washing process - this is also given space in the operating instructions. All dishwashers are equipped with water softeners. The quality of dishwashing depends on the hardness of the tap water. Regenerating salt, which is added to the softener, removes lime from the water that might otherwise remain on the surface of the dishes.

Detergents in PMM are used only specifically intended for it - just like washing powder for automatic washing machines. They can also be used to facilitate drying. Available in powder or tablet form. Then connecting the tray with rinse aid to the operation may not be necessary. If, however, the rinse aid is used to eliminate streaks and stains during drying, the order of its use is clarified during the work process.

Maintenance and mandatory care of the dishwasher are described in the instructions.

There are also tips on how to repair the unit with minor damage. Regular cleaning of filters and sprinklers is the basis of routine maintenance. For periodic cleaning of scale, food residues and grease, it is better to use universal detergents for dishwashers and washing machines.
