Washer started throwing F3E2 code (again). At first, could clear the code, but eventually got to the point where it would not clear.
The sensor replacement is simple - unplug power, take off back panel, unplug sensor, pull sensor out of rubber grommet, apply a little water to the sensor surface to lubricate, insert new sensor and put it all back together.
The only negative... this is the second sensor I've had to replace in the last 6 months. The first replacement (from AppliancePartsPros) appears to have started failing intermittently. I checked the wiring harness (which I also replaced a few months ago for a broken motor connector) for continuity, checked the sensor resistance at the sensor and at the CCU end of the wiring harness... everything looked OK. But the new sensor appears to have fixed the problem, and APP is refunding the first sensor purchase, so all is well.
