Bosch SMS69T02EU dishwasher - Error E01, interrupting operation during the progr

Hello

I have a problem with the dishwasher ... Well, during the program throws error E: 01 more or less in half. I set it to Auto 65-75 ° C for 2h35min. and as I checked in 1h34 minute to the end of washing after draining the water which was clearly heard thrown error E: 01 - end of the program ... I had to turn it off and unfortunately it was impossible to return to this program. It has happened to me several times in a row that it turns off about halfway through the program - no further polishing and drying.

There is some foam on the dishes and they are "slippery". It's hard to say if the water is standing ... I once noticed that yes, and today even not, but after removing the filters you can see that this "chamber" is. I took out the pelvis several times, rotated the rotor and did not notice any obstacles, and the rotor rotates.

I have no idea what it could be ... After all, the dishwasher washes quite well, but you can see some dysfunctions ... However, this lack of drying and polishing is bothersome ... However, I do not know much about repairs so I will probably not take them not to spoil something, but maybe you know what it can be and what to do? I'm thinking of calling Bosch just how much will it cost ...

I am asking for help and thank you.

E01 suggests a problem with the control module.
What do capacitors look like, isn't there any leakage or wetting of the electronics or wires?

I don't know that, and I don't even know how to get to this electronics, but I don't know how water could get there ...

There are two electronic modules in this model. Module (control) in figure 570 (page 5 on the top slightly left) and module (power supply) item 103 (page 1) and additionally display no. 102. I attach the assembly drawing.
