I have this dishwasher that has worked well for a couple years.
Recently, it began lighting the red cancel light during all stages of the wash cycles. It would be on for several minutes, then half way through the wash cycle it would turn off, only to turn on again moments later. This repeats itself probably a half dozen times or more throughout a full cycle.
I've looked through the service sheet behind the kick plate and there is no information as to what the cancel light means when lit during a cycle. We had a repair company come out and they decided it was the main control board. They put a new board in and it worked fine for a few days but the exact same problem is back now.
I've done a diagnostic cycle and a full wash cycle after that and the same issue occurs repeatedly. The red light also comes on during the diagnostic cycle. According to the service sheet, the red cancel light, (only listed as "All other status LEDs"), is not supposed to illuminate except for the first six seconds which is purely an LED operation check.
I can find no information as to exactly what the red cancel light means during a wash cycle. Does anyone know?
