To pump out the excess tub water while failing to complete spin cycle;

Enter Service Mode by simultaneously pressing and holding the Enviro Plus and Spin Only keys for three seconds or the display reads “00”

Pressing the Delicates key will lock the lid. Now press the Presoak key the drain pump will turn on. Stop with off button or hit the Presoak key.

This process is documented in the Service Manual. I would go to page 16 of the SM lower right hand part of page, Board Output Test and turn on the drain pump in service mode to pump out the tub.



If I could ask you to do a little troubleshooting;

It sounds like the wash/agitate cycle completes and you enter into the spin cycle of the selected wash cycle is that correct. When the wash cycle fails does the Cycle Status LED indicate that the washer is in the Spin cycle?

With a empty wash basket no wash load in the basket and you start a Spin Only cycle will the Spin Only cycle complete?

If the washer will start the cycle do you hear and loud Spin Only cycle noise such as metal against metal grinding noise?

With the washer off and no clothes in the wash basket can you open the lid then Spin the wash basket as fast as you can in the CCW direction the only direction. The wash basket should spin CCW several rotations and coast down to a smooth stop dose it?

I’m checking for Outer Tub increased bearing resistance…..Rich

I would start by removing the front cover of the machine follow all safety warnings in the Service Manual.

Follow the first few steps in my Clutch Fix post to remove the front cover.

Then let me know if during the water fill cycle the machine rotates the wash basket CCW in a slow spin during the water fill cycle before the machine stops and we will go from there. Give me all the detail you see with the front cover off I need to know if the wash basket is rotating CCW during the washer fill cycle.

You can lift the washer top up a slight amount to observe the slow CCW spin of the wash basket. I’m checking that the outer tub bearings are not seized……Rich

Hello n8mtsn,

I would pull the 120VAC power cord to the washer for 10 seconds then power back up.
See if you can get into service mode. To enter Service Mode press and hold he Enviro Plus and Spin Only keys for three seconds or until the control beeps and the display reads “00”. If you can’t get into Service Mode I feel you have a Control Board issue/failure.

If you can get into Service Mode then go to page 15 of the SM and we want to try a Quick Service Cycle test. Follow the instructions to enter the Quick Service Cycle test and let us know the results. If the test will run it will take about 10 minutes.

The motor is known to have bad windings. Do a search for "Neptune Washer will not start" Also just inside the control panel where the start/stop sw is should be a paper folded with the diagnostics test and schematic. It is tucked under the pressure sw attached to the back. If not there then search "Maytag Neptune motor phase test" There is also a Service Manual FREE at Goetlieh's site.
