I have a Whirlpool GU940SCGQ2 that is not responding, Dishwasher panel light for normal wash continues to flash without the machine running. I pushed drain/cancel and it began to flash, as well as the lock control light began flashing. Opening and closing the door resets the lights but the Normal Wash light starts flashing again. At one point I got the “Cancel/Drain” to work, it drained the unit of what little water was in it and then stopped and reset. Cutting power then reapplying power results in same conditions. Non operable. Possible heater element? Control board failure would be not so great. Any advice is appreciated!
