Neptune MAH3000 Stops

I just installed a Waxmotor Kit in our MAH3000AWW without success. Installed the Waxmotor and the Q6Transistor. The R-11 Resistor was not cooked it was exact same resistance value as replacement resistor. Here's the scenario: Our Neptune will start when set to a normal cycle and begins filling and about 30 seconds or so later it quits and the on light goes out. If you move the Timer to Spin and push start the light comes on and the door lock light and locks. The water begins pumping out. It seems to run the pump until all water is out then the machine stops and lights go out. It does this on all cycles and at all settings. Will not spin when timer moved to spin cycle. Do I need to replace the MCU or ???? I believe the Timer is fine. I am capable or troubleshooting.....just not sure where to go next. Thanks, GARY

    MAH2000 does the same, starts, slow rotattion for prewash, loud and slow, then after a while the motor kind of whines and kind of gets stuck as if it had centrifugal starters that do not work. Stops and lights go off.

    I changed the board and timer, do not know what else to do.

    any ideas?

    I have the same problems and the washer stops and does not spin . Exactly as you described. I thought it was the timer or waxmotor , so knowing you changed it and it didnt work keeps me confused. Does anyone know what to do? I have unpluged and pluged every wire and checked circuit boards. Not sure what to do. My husband can't bend under washer so tring to fix myself.

    I also had the same problem . I heard some loud growling noises and grinding noises now it doesnt spin at all. I thought is was because the load was heavyer then usual. Doesnt seem to work at all now and will start for a minute then shut off on any cycle and does not spin. I have checked through everything. About six months ago this happen and I was checking wires and felt the wire on the back of the motor had loosen (three wire connection) , I pushed it back in and then it worked fine till now. Can anyone help? I dont want to just start replacing parts. Should I buy new washer.

You probably need the motor conversion kit 12002039. This Neptune motor / motor control board has a high failure rate. To determine this you need to remove the front cover and inspect the motor control board near the floor on right side for burnt components or a blown 10 amp fuse. If you have burnt components or a blown fuse then your motor control board has failed and needs to be replaced. See for Neptune disassembly pictures and to order the 12002039 motor conversion kit.

Hello, The earlier Maytag Neptune front loaders have a balance ring on the inner tub that has liquid in it and that causes the sloshing sound when you turn the tub by hand. That is normal.

Sometimes there is water that fills in my washer after I use it. It does not happen right away but by the next day. I don't know the model but I do know this is an old have had it for...

Q - My washer seems to keep filling  with water, the water keeps coming in the washer and going out the drain without the washermotor running.
A - This often is a drain hose that is too low or a drain hose that has been pushed too far down inside the stand pipe....the water is actually siphoning out of the washer. Do not "seal" the drain hose to the house plumbing pipe, this will also allow the water to be siphoned out.

Stops between cycles

sounds like a bad motor control board. It is located at the front rt bottom and will probably show a burnt spot in it or the fuse will be blown. You must replace motor kit.
