Why don't tablets dissolve in PMM?
There are many reasons for partial dissolution: from incompatibility of the product with equipment to poor water pressure.
PMM tablets
Dishwasher incompatible
In some cases, the problem with dissolving tablets arises due to the fact that not all modern household chemical products are suitable for older dishwasher models that do not have a product recognition system. Sometimes the tablet simply does not match the size of the cuvette.
It is also necessary to take into account this point: each brand of equipment has its own type of detergent. Tablets without regenerating salt are not recommended for dishwashers from Hansa and some other brands. A number of Bosch models require products containing phosphates, while others cannot use them.
To correctly select a product for a specific PMM model, read the user manual.
Dishes are not placed correctly
dish basket
Adhering to the correct placement of dishes in the washing chamber is necessary not only to ensure access of water to all items. Incorrectly placed objects interfere with water circulation, which prevents the tablet from dissolving. Make sure that large kitchen items do not block the dispenser valve.
The detergent compartment is clogged
The hole in the detergent compartment can become clogged with limescale or food particles over time. Therefore, water does not pass through the dispenser valve and does not dissolve the tablet. Do not forget to use a regenerating salt composition for PMM, and remove any scale that appears with vinegar.

The flow filter is clogged
Impurities and food debris periodically clog the holes of the flow filter, so water flows into the washing chamber slowly. Weak pressure does not allow the tableted substance to dissolve completely.
To clean the filter, you need to turn off the water and disconnect the hose from the machine. The mesh can be washed under pressure. Citric acid will help get rid of stubborn stains.
The holes in the impeller (spray rocker) are clogged
The pressure of water entering the chamber decreases when the sprinkler nozzles become clogged. Remove the impeller and clean it with soapy water and a brush. Make sure that the machined part fits into place and moves without difficulty.

Violation of storage conditions
Tablet detergents must be stored in a dry place, as moisture deteriorates their properties. This is especially important for a product with a soluble coating.
Pipe pressure
Another reason for incomplete dissolution of the tablet may be insufficient pressure in the centralized water supply system. This happens during emergencies or plumbing work.
To check the water pressure, open the tap. If the version is not confirmed, look for another reason.
Other reasons (violation of tablet storage conditions, insufficient water supply)
The tablets may not dissolve due to insufficient water in the machine. The flow filter may become clogged over time, resulting in the device being unable to draw water normally. In this case, it may not give an error, but continue the washing cycle. As a result, the tablet will not dissolve.
Important! Each detergent contains a large number of elements that must be stored in a dry environment. When moisture gets on the tablet, its properties begin to deteriorate. Branded products are often produced in a soluble coating. If you store it in a humid environment, the packaging will be damaged. It is not recommended to purchase such products.
Malfunction of individual parts
The source of the problem with using tablets in the dishwasher may be one or another technical problem. If you do not have the necessary knowledge and tools, it is better to contact a service center. As an option, study lessons on self-repair on this site.
Is a dishwasher profitable?
Oh yes! No
Dosing system malfunction
The detergent dispenser can not only become clogged, but also fail. When operating properly, the cuvette should be completely emptied of its contents during the operating cycle of the machine.
When loading the tablet into the compartment, make sure that it is dry, otherwise the product will swell and dissolve incorrectly. Your hands should also not be wet.
Problems in the circulation pump
To dissolve tablet detergent, a certain amount of water pressure is needed. The necessary pressure is created using a circulation pump. If this element fails, problems may arise with the dissolution of the multifunctional tablet. It is better to entrust pump repair to a specialist.
Recirculation pump
Broken water heater
The accumulation of limescale on the electric heater gradually disables it. If the heating element burns out, the water will stop heating. When cold, any detergent dissolves poorly.
Broken impeller
Incorrectly placed utensils may obstruct the movement of the impeller and cause it to break. If the tablet does not dissolve and the dishes remain dry and dirty, check the serviceability of the impeller. If it malfunctions, it will have to be replaced with a new one.
Have you set the water hardness in PMM?
Yes, of course. No.
The main reasons for incomplete dissolution of the detergent tablet in the dishwasher
There are several reasons why tablets do not dissolve in the dishwasher. The main ones are:
The dishes are not loaded into the appliance correctly.- The tableted drug has expired, it has frozen or become wet.
- Water pressure is weak.
- The compartment where the tablet is placed is clogged.
- A product with insoluble containers is used together with packaging.
Before starting work, it is recommended to test one tablet by dissolving it in a glass of water. It is necessary to make sure that the pressure and filling are correct, and that the device is in good working order. If the parameters presented are normal, you should call a technician; something must have happened to the machine itself.
Dishwasher incompatible
Detergents may not be suitable for the machine if they are modern and the machine is old. In this case, the dishwasher program is not able to properly dissolve the product. It may remain in the cuvette.
Incorrect operation of the dishwasher
Attention! In some cases, the user of the device independently sets the wrong washing program. You must carefully read the instructions for using detergents. You should put funds into the device correctly. You also need to choose dishwasher tablets correctly, according to the newness and brand of equipment.
Dosing system malfunction
The structure of the detergent cuvette in dishwashers is complex. The following main components are distinguished:
- Pill compartment.
- Gelya.
- Powder.
- Rinse aid.
The tablet compartment is equipped with a special valve. It is this that can work incorrectly if the dishes are placed incorrectly, or if there is a blockage. In this case, the tablet will not get wet well.
Malfunction of individual dishwasher parts
Dishwasher tablets may not dissolve in the dishwasher if certain parts of the appliance are faulty. Problems may arise with:
- heating element (low temperature). The temperature should be at least 60 degrees.
- The temperature sensor is not working. It may not give the water heater a “command” - “heating”. In this case, the tablet cannot dissolve.
- The impeller is broken. When the dishwasher is running, the impeller begins to rotate. If the utensils are not positioned correctly in the appliance, they may break the rocker arm. It is not possible to repair the impeller yourself.
- The water heater is broken. A part may burn due to scale formation on it.
- Problems with the circulation pump. The presented part is responsible for the required pressure in the machine.
It is not recommended to replace failed equipment elements yourself! It is better to seek help from professionals.
We fix the breakdown
If there is a problem with dissolving the tablet, experts advise checking the serviceability of the equipment using powder. If it is also poorly dissolved, the reason must be sought directly in the dishwasher device. One by one, check and clean such accessible parts of the machine as:
- filters;
- sprinklers;
- detergent dispenser.
If these steps do not bring results, you will most likely have to contact a specialist to repair or replace some parts.
How to fix the problem yourself
If technical problems occur, you should carefully check the machine parts.
In-line filter: located behind the inlet hose. Turn off the water and disconnect the hose. Then you get the mesh. You need to see if it is dirty. If there is debris, it should be eliminated, then an additional filter is installed. The mesh itself is washed with running water. If this does not help, you can soak it in water with citric acid dissolved in it.- Fill Valve: Located behind the filter. It's worth checking to see if it's clogged. If there is a problem, you need to fix it.
- Sprayer: in this case, the nozzles may become clogged. As a result, the water supply pressure and the quality of washing are reduced. Close the hopper door, remove the sprayer from the tray, clean the holes with a toothpick, and rinse them with water.
By properly caring for your dishwasher, you can avoid problems with breakage of its individual parts!
Recommendations for use
For proper functioning of the PMM, follow the advice of experts:
- Read the instructions to find out which detergents are suitable for this model.
- Study the label of the tablets to find out the nuances of their use.
- Regularly clean the device parts from scale and dirt.
- After each working cycle, rinse the cuvette and dry the chamber with the door open.
- Arrange dishes in accordance with the diagram provided by the manufacturer.
Buy high-quality household chemical products and do not forget that it is better not to use multi-component tablets for express modes, the duration of which is less than 60 minutes. This time may not be enough for the tablet to completely dissolve.
Multifunctional tools optimize your dishwasher's workflow. Identifying the reason for their ineffective action is necessary not only to ensure that the dishes are washed well, but also to identify equipment malfunctions.
Rules that will ensure complete dissolution of detergent products
There are some rules for using tablets in dishwashers. One tablet is enough for one sink, and you can wash about 12 sets of dishes. You need to choose the washing mode correctly. 3 in 1 tablets can only be used in long-term modes - lasting more than 1 hour. It is important to store the tablets correctly. They must be in a dry place. If you purchased a detergent with a soluble coating, you should only handle it with dry hands.
So, dishwasher tablets are a convenient solution, but you have to use them correctly. Otherwise, they will be ineffective and may cause equipment failure.
