Dishwasher KRONA error E3 ⇐ Chrono

[Master]

The loaded dishwasher with a short wash cycle (without drying) does not heat the water and constantly displays error E3, but if you just restart it for the same cycle without dishes, it heats the water perfectly and washes according to the program. The filters are clean. Well, it doesn’t want to work in the loaded version. The reason of that?
