Electrolux esl 9450lo dishwasher freezes at the last minute ⇐ Electrolux

[Dmitry Tregubov]

Hello, please tell me Electrolux esl 9450lo dishwasher hangs at the last minute on long modes and continues to wash indefinitely and the display shows 1 minute. There are no leaks, set according to level, power through the stabilizer, water through the filter. It heats the water.
On the short mode, 30 minutes with hot water and the rinse cycle works normally. Finishes and drains the water. Namely, long modes continue to wash ad infinitum. There are no blockages, the water is drawing normally.
What could be the reason? Where to dig? And how can my model be put into service mode to test the nodes. Thank you
