Dishwasher has had intermittent drainage failure. It now won't drain at all. I tried a new drain pump, but that didn't fix it. I am wondering about the control board. When I use cancel to force the drain cycle, there is an audible click but no pump activity. Voltage at the drain pump measures about 45 volts after the click from the control board. Do you know what the voltage to the pump should be? Does this sound like a board problem or might I have 2 bad pumps? Thanks,
ANSWER Hello Steve,
The power coming to the pump should be 120 vac. If you are only getting 45 vac then you will want to check the wiring from the pump to control board and insure that there is not loose or broken wiring. If this checks ok the you would need new control board.
