Hi

A Door Lock Error occurs if the door cannot be locked. It will try to lock it six times before displaying the error code. It has happened because Door lock mechanism is broken or removed from door. It may also happen due to Door switch/lock unit failure. To resolve the issue follow these steps---
1. Unplug washer or disconnect power.
2. Check door switch/lock unit.
3. Check the wire harness connections to the door switch/lock unit and Central Control Unit (CCU).
Hope this helps...Please post back if you need more information.

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.
