Bosch SMV59T00EU/02 Dishwasher: Error E-01, Module Replacement or Other Causes?

Good evening.

Error E-01 appeared in the Bosch SMV59T00EU/02 dishwasher. On the forum, most of the posts indicate burnt electronics. I took out my module and it looks like new, at least visually. Does E-01 definitely indicate the need to replace the module or is it something else? Please give me tips.

Not necessarily, the module can be repaired, which I have done several times in the last week.
I do not know the origin of the damage, but in 80% of such damages (provided that it was not caused by overvoltage), we have to replace the drain pump. I recommend the original unfortunately.

Piotr2608, yesterday after removing the photo module and reconnecting the cubes, I released 2 cycles 45-55st and 65st and both passed without errors.
The only thing that puzzles me is about halfway through each cycle, the water jacket on the left side of the dishwasher filled up and emptied several times (over and over again). The dishwasher then did the rest of the cycle and finished without error. But the water jacket was empty, and should it have been filled at the end of the cycle?
I checked the solenoid valve at the bottom of this coat and it is operational (valve in the pictures).

Let's leave the water coat alone - you're paying too much attention to detail right now.
When you bought a dishwasher, was there water after the first wash or was it not in the water jacket?

We are interested in the actual state of affairs. There are no errors yet, so wash calmly and watch the dishwasher, pay attention to which specific program the error code will appear on.

When was the last time the dishwasher was washed before error E01 appeared?

Hmmm, I have no idea because I didn't take it apart but when about half a year ago after washing there was water at the bottom, I dismantled the dishwasher and it turned out that this valve was jammed and did not retain the water from the last rinse in the water jacket. After cleaning the valve, the water remained in the jacket after washing. Anyway, this is an element of water saving - it is used for the first rinsing - but ok, never mind, because it does not cause the e-01 error, it is the result of yesterday's observations.

I turn on the dishwasher almost always on the eco 45-55st program and practically every other day. Before the E-01 error, there was no exception (e.g. holiday break or something like that). There was also no power outage.
