Used SD4P1B Bosch. Error E01 after being transported on its side ⇐ Bosch

[Arslanfah]

Good afternoon
I bought my parents a used car SD4P1B on Avito Bosch (not built-in 45 cm). When I bought it everything was fine.

Immediately after connecting (2 months after purchase and transportation on its side in the trunk) it started displaying error E01
Most likely due to improper transportation (there was still water in the dishwasher, although I tried to empty everything). The normal voltage is 230 V.

The behavior is as follows: Immediately after switching on, the ECO mode flashes and the display shows the time 3:05. After 2-3 blinks, the display changes to E01 and also blinks. The light in ECO mode stops blinking.

Sometimes (once every 10-15 starts) it is possible to start the machine by holding down the on button and pressing Start before E01 appears. By removing your finger from On, the machine can completely go through the entire ECO cycle (heats the water, pump runs, dries). But if you open the door and close it, E01 comes out again. Sometimes you can even have time to change to another mode instead of ECO (on->hold on->mode->Start->remove your finger).

Please tell me what could be the problem? Transporting a car back from the village to the city is far and problematic.

Thanks for the answers.
