Thanks to built-in self-diagnosis systems, dishwashers (hereinafter also referred to as PMMs) can independently localize a fault. So, error codes for Electrolux dishwashers allow you to determine the nature of the breakdown in household appliances from this well-known company.
If you call a technician to repair your dishwasher, tell him the error code in advance - this will speed up the repair.
What do various fault codes mean and their interpretation?
If you know the decoding of fault codes, you can fix most PMM breakdowns with your own hands. For all models of the Electrolux, Zanussi and AEG brands, the coding of errors appearing on the displays is the same.
There may be slight differences in dishwasher models without a display, where alphanumeric symbols replace flashing LEDs. Each fault corresponds to a certain number of signals from the END indicator or other LED, followed by a pause for a short period of time (5-6 seconds). Then the series of blinks is repeated.
This is how a malfunction of an Electrolux dishwasher is displayed in the form of a code
The explanation of alphanumeric combinations and light signals should be in the instructions included with each dishwasher. If the document is missing for some reason, we suggest that you familiarize yourself with the table, which provides a list of codes indicated by the self-diagnosis systems of dishwashers:
| Code | Number of indicator flashes | Description of the breakdown |
| i10 | 1 | A sufficient amount of water is not poured into the PMM tank or there is no liquid supply at all |
| i20 | 2 | The waste liquid does not drain or is poorly removed by the pump into the sewer system |
| i30 | 3 | The Aquastop system signals that water has leaked into the dishwasher tray |
| i50 | 5 | The triac that controls the operation of the circulation pump may be faulty, causing the pump to stop functioning |
| i60 | 6 | A tubular electric heater (hereinafter also referred to as a heating element) does not heat the water or does not heat it quickly enough. Possible overheating of the liquid |
| i70 | 7 | The temperature sensor is probably faulty, its resistance does not meet the standards |
| i80 | 8 | Data is not loaded correctly from the EEPROM memory into the central processor of the electronic control unit (hereinafter also referred to as the ECU) |
| i90 | 9 | Error in the PMM operating program |
| iA0 | 10 | Sprinkler arm does not rotate |
| iB0 | 11 | The water turbidity sensor does not transmit information to the ECU. It may be malfunctioning |
| iC0 | 12 | The interface board cannot transmit information from the control panel to the ECU |
| iD0 | 13 | The tachometer sensor does not control the rotation speed of the circulation pump motor |
| iF0 | 14 | For a certain time, liquid has not been added to the PMM tank to the required level (in cases where it is required to be topped up) |

In many cases, alphanumeric indications of errors in the operation of the PMM disappear after rebooting the dishwasher. To do this you need:
- turn off the dishwasher;
- unplug the plug from the socket;
- wait 15-20 minutes;
- connect the unit to the network and turn it on again.
How to reboot the equipment:
- Unplug the machine;
- Wait 10-15 minutes;
- Reconnect.
Has the error appeared on the display again? This means that you need to find its decoding and ways to fix the problem.
| Fault code | Number of indicator flashes | What does it mean? | Reasons for appearance | DIY repair |
| i10 | 1 | Water does not get into the bunker. |
| Open the tap, make sure the water supply is normal or wait until it is restored.
|
| i20 | 2 | The waste liquid does not leave the tank. | What's happened:
| How to fix:
|
| I30 | 3 | Meaning: the Aquastop system has activated. | There was a leak in the machine. When water enters the pan, the float rises, which turns on the sensor. This is how leakage protection works. | Inspect the PMM housing at the time of leakage:
|
| I50 | 5 | Short circuit of the circulation pump triac. | Happens during power surges in the network. | Diagnostics and repair of electronic boards and circuits. Contact the service center. |
| I60 | 6 | Incorrect heating control. | What happened:
| What should I do? Diagnose and replace:
If a component breaks, a new element is installed. |
| I70 | 7 | The NTC thermostat does not work. | An open circuit or short circuit has occurred. | Inspect and replace the sensor if there is a problem. |
| I80 | 8 | No contact with EEPROM memory. | The circuit is broken. The controller is damaged. | Contact a specialist for help. |
| I90 | 9 | MCF or CCF programming error. | Problems with the main module. Can't install the program. | |
| iA0 | 10 | The sprayer in the tank does not rotate. | There was a power surge in the network and operation was blocked. The dishes are not placed correctly in the hopper. A foreign object has entered. | What to do:
|
| ib0 | 11 | The turbidity sensor does not work (if installed). | If the sensor does not give a signal within 15 seconds, it means it has failed. | Check the condition of the transparency sensor, inspect the wiring harness. If damaged, all elements are replaced. |
| iC0 | 12 | There is no connection between the electronic board and the user interface. | The connecting circuit is probably broken. | Diagnostics. Contact the workshop. |
| id0 | 13 | There is no contact with the Hall Sensor. | If the circuit is broken, the module will not be able to communicate with the tachometer. As a result, the engine speed will not be adjusted. The sensor may be faulty. | Inspect the sensor and its contacts. Broken parts need to be replaced. |
| iF0 | 14 | The time for drawing water into the tank has been disrupted. | During the allotted time, a sufficient amount of water has not been filled into the hopper, and the machine is already moving on to the next steps. The problem is in the control system. | It requires diagnosing the board and installing a new part if necessary. |
In addition to codes, problems can be detected by indirect signs. In this case, the operation of the dishwasher is disrupted.
Elimination of breakdowns associated with blockages, collection and drainage of water
Possible reasons for the i10 error to appear are as follows:
- there is no water in the water supply or the ball valve for its supply is closed at the inlet;
- the inlet filter is clogged with debris;
- the inlet hose has become kinked;
- the inlet valve does not open.
To eliminate the damage, check the presence of water in the water supply and the condition of the above parts. The filter needs to be cleaned, the hose needs to be straightened. It is easy to purchase and replace the fill valve yourself, or call a specialist to diagnose and repair the part.

Error i20 in an Electrolux dishwasher indicates that one of the following problems has occurred:
- the drain filter is clogged;
- the impeller of the drain pump is blocked by debris;
- a blockage has formed in the drain pipe or hose;
- The water level sensor in the tank does not work.
Filter element in Electrolux dishwashers
First of all, you need to clear the filter of debris, then check to see if the pump impeller is jammed with broken dishes or debris. To do this, remove the pump cover located under the filter. A kink in the drain hose is also easy to fix. If the above steps are completed and the water still does not drain, you will have to replace the pressure switch.

The alphanumeric combination i30 on the display indicates the activation of the Aquastop system. Possible causes are damage to the tank, one of the pipes, hoses or their connections. In this case, the inlet solenoid valve immediately shuts off the water supply to avoid flooding. It may be necessary to completely disassemble the PMM for repairs, so it is better to call a specialist to your home.

IF0 is another Electrolux dishwasher fault code, informing the user that water is being drawn into the reservoir very slowly. In this case, the machine will wash tableware with less liquid. Eliminating such an error is simple - after the wash cycle, drain the water, add it again, and the emergency coding will disappear.

The meaning of brand equipment fault codes
Many Electrolux dishwasher models are equipped with a self-diagnosis system; they issue a code that can be used to immediately determine the cause of the problem. The message is displayed on the monitor in the form of an error code, for example i60 or i20, etc. If there is no separate display, problems are indicated by a flashing END indicator.
Problems with collecting, draining or heating water are most common.
Here are the codes for them:
- i10 occurs if no water flows into the dishwasher chamber within a minute from the start of the cycle, it is recommended to check the condition of the tap, hose (perhaps it is simply pinched), and also clean the filters at the water inlet to the dishwasher;
- i20 shows that there are problems with the drain, you need to check and clean the drain filter and drain hose, as well as the drain pump and water level sensors, damaged elements will have to be replaced;
- i30 indicates that leakage protection is turned on; you need to drain the water accumulated in the pan and restore the position of the float sensor or replace the hose in the mechanical version of the Aquastop system;
- iF01 indicates that water has been entering the chamber for too long, usually this error corrects itself after the end of the washing cycle, it would not hurt to check the water supply system to carry out preventive work;
- i60 - a signal about the absence of water heating or about significant overheating, which happens if the heating element has burned out, there is a breakdown in the electrical circuit, the circulation pump, temperature sensor or control board has broken down.
Options for eliminating i60 type breakdowns were described above. In the following video you can watch the repair of a built-in dishwasher that generated this error:
Overheating may occur if there is not enough water inside. In this case, you need to follow the recommendations for the situation with the i10 stake.
The following codes indicate serious electrical, electronic and other similar problems:
- i50 – circulation pump triac is broken;
- i70 – the heating element thermistor is damaged;
- i80 – problems with the control module firmware;
- i90 – a malfunction of the control board, which does not allow you to select the operating mode of the device.
Replacing a damaged triac or thermistor is relatively easy. But to reflash or replace the control module, you will have to contact a service center.
Other common problems with Electrolux dishwashers include the following codes:
- iA0 indicates that there is no rotation of the indicator rockers, usually this is due to improper placement of dishes in the chamber or due to a voltage drop;
- iB0 – transparency sensor failure;
- IC0 – lack of communication between the panel and the control board;
- id0 – the tachogenerator of the circulation pump is broken, the water does not heat up.
This type of breakdown is complex; you will have to use the help of a service center. Failure codes do not always accurately describe the problem that has arisen in the operation of the dishwasher. It happens that a malfunction occurs due to violation of operating conditions or for some other reasons. If this factor is not eliminated, breakdowns will occur again.
Problems with water heating
The i60 designation makes it clear that one of several problems is possible:
- The heating element has failed;
- the temperature sensor is faulty;
- the cable wiring coming from the computer is damaged;
- The control triac in the control unit does not work;
- the circulation pump is broken;
- There is too little liquid in the reservoir.
If you have the skills to work with tools, you can replace the heating element or thermistor with your own hands. But troubleshooting wiring and ECU problems is best left to an experienced specialist. A malfunction of the thermistor is indicated by the i70 combination on the dishwasher display.

Sensor malfunctions
Dishwashers use various sensors that monitor operation at all stages of the program. With their help, the temperature, level and condition of the water are controlled.
Typical errors in Electrolux dishwashers due to problems caused by sensors are displayed in the following way:
1. Code ib0 (11 blinks) - an error has been detected in the operation of the turbidity sensor, which monitors the condition of the water using a light beam. Possible reasons: • dirt deposits on the sensor;
• level relay failure;
• clogged drain system.
Remedy: • clean the sensor from dirt;
Control system malfunctions
If such breakdowns occur, diagnostics and repairs should be carried out by qualified technicians. For example, if the circulation pump does not work (error i50), the reason may be either the pump itself or the failure of the control triac located in the control unit. In addition, the triac may not receive a signal generated by the processor. Similar situations may arise when codes from i80 to iD0 are displayed, when the sensors do not respond or the ECU is broken.

We looked at the most common breakdowns of Electrolux dishwashers. We hope that this material will help you troubleshoot problems yourself.
Problems due to clogs in Electrolux dishwashers
Water is drawn from the water supply network through a valve and filter. Due to rust in the pipes, they can become clogged.
Dirty water is purified by filters for re-washing. Waste water is pumped into the sewer using a drainage pump. The drainage hose is sized to allow food debris to pass through unhindered.
Typical errors of Electrolux dishwashers due to problems caused by blockages are displayed in the following way:
1. Code i10 (1 blink) - an error has been detected with water entering the tank at the set time. Possible reasons: • the valve, filter or hose in the water filling system is clogged;
• the water supply from the water supply is cut off.
Remedies: • check the presence of water in the tap of the apartment's water supply network;
• the functionality of the inlet valve is checked;
• the inlet filter mesh is checked and cleaned;
• inspect the inlet hose to ensure there is no blockage.
2. Code i20 (2 blinks) - an error has been detected with draining waste water. Possible reasons: • the drain filter, pump or hose is clogged;
• the drain pump (pump) has stopped;
• the hose for draining water is crushed;
• the pressure switch (level switch) did not operate at the time set by the program.
Remedy: • clean the filter and hose from dirt;
• the pump impeller is checked to ensure there is no debris, food debris or broken glassware on it;
• the position of the drain hose is corrected;
• the operability of the pressure switch is checked. If it malfunctions, it is replaced.
