Door Lock The power supply failed during a wash cycle, when power was restored and the cycle completed the door locked light remained on as did the final spin light. After a further two spin cycles the door remained locked. Turning the machine off did not work either. What can i do?

Sounds like door lock if failing. If you push against door while its buzzing and noise level changes. I recommend replacing door lock assembly

Because of the high spin speeds of front load washers, the doors are equipped with a latch and lock mechanism to prevent the door from being opened during the washers operation. These locks will often be actuated by a solenoid or wax motor to ensure they remain latched during the wash cycle. This model uses a two stage lock that latches the door when the load starts, and then when it is time to spin, the second lock engages to ensure the door is properly secured prior to beginning the spin. When this second lock engages, it also closes a set of switch contacts (the auxiliary door switch) telling the control board the door is closed and locked. If for some reason this switch is not closed, the washer will tumble during what would normally be the spin cycle until the entire cycle is complete.

Is your door lock light on when machine is in use? I am having the same issue as you and I believe it is because my door is not locking during use.

Please see the following Whirlpool / Maytag service manual for Neptune washers.
https://secured.whirlpool.com/Service/SrvTechAdm.nsf/2cd44500d572193285256a45004fd9d6/dc59d905140253e18525729c005765f4/$FILE/Maytag_Neptune_Washer.pdf

On page 3-1 the manual explains that if the washer shuts off during the spin cycle, the problem points to a weak spring in the door lock mechanism.

"Shuts OFF In The Middle Of The Spin Cycle:
During the spin cycle, the machine control
monitors the door lock mechanism to ensure
the door is locked. This is done through the
door lock enable switch. During "lock mode,"
the shaft of the door lock mechanism is
pressed forward by the door lock wax motor,
and the shaft presses in the button of the door
lock enable switch. If the machine control
board sees the switch OPEN during the spin
cycle, the machine control board will automatically
shut the washer OFF. This is caused
by a weak spring in the door lock wax motor.
Replace the complete door lock mechanism.

If Pause/Cancel does not work:

1. Unplug the washer or disconnect the power for one minute.
2. Plug in the washer or reconnect the power.
3. Re-select the cycle and press Start.

NOTE: If the error remains on the display, and all of the other conditions above have been checked, call for service.

You probably have a bad door latch or door interlock. Both, if defective will cause the symptoms you describe. The door must remain closed and lock before a wash cycle will begin, and for it to complete properly.
