Went to this last week, door not locked flashing.
Removed motor to check brushes, not even half worn and comm didn’t look that bad.
Gave the comm a clean with comm stick anyway, stuck the motor back in and the darned thing worked perfectly, nice and smooth on spin with no arcing etc.
Motor connections rock solid BTW.
A week and 10 or 12 washes later and it is doing the same thing.
Is this likely to be a duff motor or the PCB?
Jim.
