LTF11S111 error 13 ⇐ Hotpoint-Ariston

[English]

Help with advice. After starting any program, water is pumped out, then water is drawn in, then after half a minute everything stops and 13 lights up on the display. I experimented: I removed the chip from the heating element, sat down with the cartoon and turned on the dishwasher again, the dishwasher started working, the voltage on the chip was 13 volts. I haven’t seen 220 volts even once since I turned on the program. I examined the board, everything seemed to be normal, there were no scorched parts, no oxides either. I didn’t check the relay, there is no diagram.
I removed the circulation pump, the windings are normal, the graphite bushing in front of the impeller requires replacement, there is wear on one side, I turned it about 180 degrees until the replacement arrives.
Tell me how remove error 13?
