 bosch sms50e02ru - no water supply

Post by nickolai.cotov »

Problem with the dishwasher - bosch sms50e02ru - the machine does not start, the indicator is on - there is no water supply and no salt indicator.
I started looking for the reason - I looked at the filters - they are not clogged, the leakage sensor is normal (the pan is dry) by manipulation - by pressing it, it is activated and turns on the drain pump.
I come to the conclusion that there is a problem with the aquastop system - that is, something is blocking the operation of turning on the solenoid on the inlet hose. When voltage is applied, the solenoid works - water flows through the hose to the dishwasher.
A reed switch type sensor is installed on the plastic pipeline on the back of the dishwasher; when manipulating the magnet, the solenoid on the inlet hose is switched on briefly (5 sec.) - water is supplied. After three such switches on - does the drain pump turn on?
What could be the problem, does anyone know? What is blocking the flow of water into the machine? Where to look for the cause and how to remove it?

Yes, I checked everything that can be checked and found that on the control board elements near the varistor were damaged: two diodes - the markings of which I can read and two transistors - the markings of which are not readable - can someone tell me the markings of these transistors?
