When connected to the network, the water inlet valve turns on and does not turn off. ⇐ Electrolux

Electrolux dishwasher. There is constant voltage on the water fill valve. Accordingly, excess water is drained into the pan and the drain is turned on. I took it apart and all the sensors are clean. I don’t understand what the reason is. In the board or in the pressure switch. It’s electronic here.

First of all, you need to run the service program, clear errors, check the pressure switch for channel contamination and operating resistance. If the pressure switch is working, reflash the brains or change them

How to check the pressure switch if it is electronic? Marquardt

Greetings. \Did you solve the problem? I have a one-on-one situation right now. What was the problem

[Psyu]

I came across a similar problem. When the PMM is connected to a 220 volt network, 270 volts are immediately supplied to the water supply valve, the machine draws in and drains water. Disconnect everything from the module; when connected to the network, power is supplied to the water supply valve of 270 volts

Did you solve the problem? I have the same symptoms. At first the aquastop stopped working, I installed a valve from a washing machine, I thought it was the cause. It turned out it wasn’t that, the valve gets voltage when plugged in, I changed the pressure switch and bought a new one, it didn’t help. In the control module, I changed the valve control triacs, which also did not help.

Have you decided or not?

[Sprinkler]

So what is the problem, I changed everything, the water came in the same way

[Concave Reflector System]

The problem is in the control module.

Me too!!! I got to the board, visually everything is intact!!!

There is a solution, but today I encountered the same problem and the solution did not work

Good day everyone! A similar problem, there is 220 volts at the water inlet valve. I reached the payment. The TY3001 semisistor has failed. I will change it. But I also saw a resistor R3163 in the circuit of the TY3003 seven-stor, which seemed to be scorched, the value could not be read and could not be called. Can someone post its denomination or photo? Supposedly 470 ohms.

On November 13, 2023 I wrote a question and no one answered anything. I solved the problem myself. There was a problem: when the PMM is plugged into the socket, the water inlet valve immediately activates and does not turn off. Replacing the TY 3001 semistor in the circuit for switching on the water supply valve, then replacing the resistor R3163 with a nominal value of 47 Ohms (burned out), replacing the capacitor C3103 with a nominal value of 10 nF was broken (I assume in the power supply circuit of the pump). It is possible that there is a power surge and these elements have failed. For a long time I did not dare to turn on the machine after replacing the parts... I turned it on, but the valve did not work well. Did a reboot. I selected the program and launched it (without connecting to the water). First, the water drain pump started working and was audible during operation. Then the water supply valve worked, I took it in my hand and felt a buzzing sound. That’s it. Problem solved. Reset the washing program, gave it to the children to check. After assembly and connection i.e. Launched yesterday, worked in two washing modes, no comments. Good luck to all!
