Door Unlock Non-Fatal Error

Er dU

If the door fails to unlock 20 seconds after the drum has stopped spinning with a solenoid type door lock and all other outputs have been turned off, the control will show error. To clear this error the door must unlock or open. Removing power for 3 minutes will automatically allow door lock to unlock. Make sure to press on door and then pull to unlock the door as pressure on door lock/ latch will prevent door from unlocking. Possible causes of this issue are broken shocks or clothes load causing pressure on door and door latch/lock preventing it from unlocking. If it still fails to unlock, check door lock and latch for damage. Also check door lock wire harness for damage or disconnection.
