Scott, if there is a constant 120VAC going to the main control while a power failure error starts, the failure would certainly be in the main control EBR78263902.

Kirk, the coin catch filter will need to be inspected for any clogs as well as the drain pump being inspected. If there are no clogs then the voltage going to the drain pump will need to be tested. The voltage can be tested from the main control during a spin cycle at the blue two-wire connection. The connection will have a brown wire and a black wire and the brown wire would be tested to ground for 120VAC going to the drain pump. If there is not 120VAC when the unit is in spin and should be draining, then the main control EBR78263902 has failed. If there is 120VAC, then the drain pump 4681EA2001T has failed.
