Neptune Washer Access

I'm going to try and find more info on the "UI" Code.

sounds like the locker servo is having an issue there and may need replacement contact Maytag for a replacement part

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.

The washer detects that the door is open when
starting a cycle or the door is not locking.

Close the door tightly and restart the cycle.

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.

od means the lid has not been opened for the last 3 completed cycles. here's the manual http://www.servicematters.com/maytag_library/docs/16022808.pdf

check to make sure the door is locking when it should. If the door isn't locking or sensing that its locked the washer will not go into high speed spin.

If you have changed the door lock assbly,the next thing it could be is the need for a motor conversion kit. this is something you need to place a service call on. The approx cost for part #12002039 is 240.00US

does the washer actually go into high speed spin? if not the wax motor in the door lock may be no good. that would prevent the door from locking and the indicator on the display would not light.
