Maytag Neptune MAH8700AWW with ND code
« on: June 08, 2013, 02:35:12 PM »

So we have been getting the ND code on our washing machine.  We downloaded the service manual and did some of the tests.  The pump isn't getting 120 VAC during the spin cycle so we checked the voltage at the pin 6 CN10 and pin 1 CN5 and it isn't getting 120 VAC either.  So what is wrong?  Could it be a loose wire or is it the control panel itself, or could it be a sensor?

It looks like a bad control board.  Check for a shorted pump motor, it should be 14.2 ohms +/- 7%. Make sure it's within specs, I once blew up a new control with pump that read 12 ohms. With the cost of a new board, it might be worth trying a board repair or having it rebuilt.
