We check it ourselves and decide
- We try to reboot the washing machine by turning it off for half an hour;
- We check the sensor for resistance from 20 Ohms using a tester;
- We check the sensor contacts;
- We try to turn on the rinse function, and then check the operation again.
We replace and repair
- We repair or replace the wiring from the board to the sensor;
- We repair the washing machine control module;
