this is an ntc fault the temp reading is out of calibration it keeps the door locked to avoid burns from scalding hot water it is fitted inside the wash heater.

from a previous discussion:

Wait at least three minutes after the end of the cycle before attempting to unlock your Whirlpool washer. The door will not unlock until the motor speed equals 0 and 180 seconds have elapsed since the motor control unit received the "Stop" command. If the water in the washer is warmer than 122 degrees Fahrenheit or the water level is set higher than Wool, Delicate or Hand Wash, the washer must drain before the door latch will unlock 2 Hold down the "Control Lock" button on your Whirlpool washer for three seconds at the end of the washing cycle. Listen, and when you hear the unlatching sound, the door should open.3 If your Whirlpool washer did not unlock at the end of Step 1, press and hold the "End of Cycle" button for five seconds to manually reset your washing machine.4 Unplug your Whirlpool washer and leave it unplugged for 45 minutes. After 45 minutes, plug your washer back in. The washer's programming should be reset and the door should open.5 Manually unlock the door of your Whirlpool washing machine. Make sure to unplug the appliance before completing the manual unlock. Use a screwdriver to remove the metal strip, called the toe panel, at the bottom of the washing machine. Once you've removed the toe panel, reach up inside the front panel of the washer and feel around for the door latch. Locate the tear-drop shaped tab at the bottom of the door latch and pull it gently. When you hear a click, the door should open.

Sound like the control board is bad

If the machine didnt finish the cycle due to the pump being clogged the door will remained locked also if the lock mechanism went bad, the machine will stay locked. Remove the top of the machine by taking the screws from the top back out. Once removed look down the right hand side and you'll see the lock mechanism, usually with a plastic tab you pull to manually release the lock.

1. Your Maytag Neptune washing machine displays error codes, also called "help codes," to identify specific problems with your washer. Once you close your Maytag Neptune's door, the machine locks the door, goes through the selected wash cycles and unlocks the door when the laundry is finished. Error codes appear when there are problems with the door, the inflow and drainage of water and the motor.
Do
2. Your Maytag Neptune washer displays the "do" help code when the washing machine is trying to start a cycle, but the door is open or not locked properly. If this message is displayed, close the door securely and restart the washing cycle.
FL
3. The "FL" code indicates that the washing machine was unable to lock the door after you closed it. Open and close the door tightly, then restart the washing cycle.
Sd
4. The "Sd" code indicates that you have added too much detergent to the washing machine and your laundry has too many suds. The machine will stop displaying this code if it has successfully run the suds recovery cycle, which removes the excess suds from the wash load. If the code remains, reduce the amount of detergent in the load. Use less detergent for similar loads of laundry in the future.
PF
5. The "PF" code indicates that a power failure has occurred. Restart the wash cycle. If the code still appears, check that the washing machine is still plugged in to the electrical outlet.
Nd
6. The "nd" code indicates that your Maytag Neptune is not draining as it should. Check that the drain hose isn't kinked and that the stand pipe isn't clogged. If you find either of these problems, fix them before restarting the washing cycle.
LO
7. The "LO" code appears when the washing machine has finished the selected wash cycle, but cannot unlock the door. Verify that the door is closed properly, push the "Off" button, and wait two minutes. The door should unlock and the error code will disappear. If the error code remains, unplug the washing machine, wait two minutes and plug it back into the electrical outlet.
Lr
8. The "Lr" code indicates that the washing machine's motor is not running as it should. Have your Maytag Neptune washing machine serviced by a certified Maytag repair professional.
   

I would have to assume you damaged your door lock assy. You can remove the bottom access panel and there will be a tab you can pull to manually unlock the unit hanging down from the door lock assy. This may work, if this does not work then you will have to replace the door lock assy. The unit will not clear unless the door is unlocked. You could also try to unplug the unit for 10 mins or so to see if it will manually unlock itself.

Hope this helps _MJ_

did you try unplugging it and plugging it back in to see if you can get it to reset? Would it buzz when you try to drain it? Does the door latch lock when it goes into the wash cycle? Usually the door latch locks when it goes into the wash cycle and stays locked. So it filled up, the door latch should lock, then should go into wash cycle. Then you said few minutes later it stops. How did you get the door open? reason i ask is Usually i would see the clothes get stuck inside the washer because the door latch is still locked when it stops. Was the door unlocked when it stoped. If so maybe something going on with the communication from the board to the door latch maybe. Did you try operatin the drain?

Clean out your filter after ref. to user's manual. Try some WD40 on the door mechanism (on machine), lock & unlock door 5 or 6 times while machine is off.
