Most of the dishwashers are connected to a cold water supply system, so without heating the dishes will simply not be washed. The fact that the heating system does not work, it becomes clear shortly after starting the dishwasher. And it is far from a fact that a ten or a temperature sensor has failed. The list of possible malfunctions does not end there, and will be discussed in detail in the article.
Possible reasons when the water does not heat in the dishwasher
The main reasons that the water in the dishwasher does not heat up are:
- malfunction of ten;
- failure of the temperature sensor;
- faulty control board.
In addition, the reasons that at first glance are not relevant to the heating of water, but actually indirectly affecting it, may be:
- improper connection of the dishwasher;
- clogged trash filter;
- improperly selected dishwashing mode;
- failure of the pressure sensor. By the way, before changing it, you should clean its contacts and check the serviceability of the wiring going to it.
The question arises - what does the filter have to do with it? Everything is simple - when the filter is clogged, there is no water circulation between the tank and the tanks, the system replenishes the water, and it does not return from the tank to the tanks. Ten does not have time to heat it. To identify this malfunction, just look during the washing process in the tank. During normal operation of the filter, water does not linger in it. If there is a problem - the filter needs to be cleaned.
If it is connected incorrectly to the sewer, there is no normal circulation of water in the dishwasher, and its temperature will not correspond to the norm, if it is heated at all. In this case, you need to connect the machine to the sewer system as shown in the instructions.
How to understand that a dishwasher does not heat water
The first sign that the dishwasher does not heat water is poorly washed dishes at the end of the washing process - it remains greasy. In addition, non-dried dishes are also a sign that the machine does not heat water.
First aid for a broken appliance
First of all, if the dishwasher has stopped heating the water, you need to go over the list of possible malfunctions and use the exclusion method:
- check the trash filter;
- try reconfiguring the machine to another mode;
- check the correct connection to the sewer;
- inspect the pressure sensor.
If the primary measures did not produce a result, it means that most likely the heater, temperature sensor or control module failed.
How to check if the dishwasher is heating water or not
In case the heating system does not work, the consumption of electricity by the dishwasher drops sharply. This is perfectly visible on the electric meter. If the heating works, but incorrectly (as with a clogged dust filter, a pressure sensor malfunction, or an incorrect connection to the sewage system), the energy consumption will not decrease, but the result of washing will be saddened - the dishes will remain cold, wet and dirty.
How to repair a dishwasher or replace parts yourself
How to fix a temperature sensor
The repair procedure is as follows:
- disconnect the dishwasher from water supply, sewage and power supply;
- we take out baskets for dishes from the tank;
- remove the trash filter, remove the mesh and the fixtures under it;
- turn the PMM upside down, disconnect the side mounts.
- disconnect the drain pipe from the plastic block with a heating element and raise the bottom of the dishwasher up;
- the temperature sensor is located in the housing of the heating unit in order to accurately measure the temperature of the water. Disconnect the wires from the contacts of the temperature sensor;
- we clean the contacts and measure the resistance of the temperature sensor;
- we take out the failed sensor, replace it, and then assemble the car.
Repair control module at home
At home, if you are not an electronics engineer, immediately contact a specialist and do not aggravate the situation with the repair. If you have the skills to work with such devices, then you can try to fix the problem yourself.
How to replace a heating element
Before changing the heater, it immediately makes sense to estimate the cost of the entire dishwasher. If the car is no longer new, it may turn out that the ten at a price will come out more expensive than it. If the game is worth the candle, then for the cause:
- remove the baskets from the hopper;
- disconnect hoses and power supply;
- remove the sprayer;
- remove the filter;
- remove the mesh;
- Unscrew fastenings for a branch pipe and Teng.
- turn over the typewriter;
- turn the pump half a turn to the right and pull, removing it;
- remove the temperature sensor, set the pump aside;
- ten is held on a rubber mount. Find it and then disconnect;
- remove the sensor plugs, pipes, then remove the heater;
- put a new heater and reassemble the dishwasher in the reverse order.
Rules to help prevent damage to the dishwasher
Choosing the right device mode
Make sure that the mode is set correctly - some modes provide heating of water to 30-40 degrees (the so-called "delicate washing"). In addition, in dishwashers with electromechanical control, it happens that when choosing a mode with a maximum heating of 30 degrees, and manual adjustment will be at 90 degrees - the dishwasher will work according to the selected program, that is, the maximum heating of the water will be 30 degrees. The operating modes are described in detail in the instruction manual of the device.
Timely filter cleaning
Include cleaning filters in the list of must-haves, this will ultimately save time and money. In addition, do not be lazy to remove food debris from dirty dishes before washing, do not complicate the task of the dishwasher and your life.
Using quality detergents
For the dishwasher to work optimally, use the detergents and consumables specified in the instructions. You do not refuel a car running on diesel with gasoline? Or do not fill the tank with a car instead of 95 gasoline 76? The same rules apply here. Do not neglect them.
