Hi below is the meaning of the error code and corrective actions needed. To open the door manually take the panel out from under the door and reach up to the door lock mechanism. On the door lock there is a tab, pull the tab and this will release the door. If you have any questions please feel free to ask. Mike

Hello,

The usually reason the door remains locked once the cycle is over is because the filter screen on the drain pump is blocked so not all the water could drain out...the door lock is tied into the pump and until the pump tells the control board that the wate r is out the door will not unlock. This tip i wrote will show ya how to take apart the washer to clean the filter on the pump.

Hi, "F21" is a Long Drain error code. This indicates that you have an obstruction in the drainage system. More than likely you probably have a clog in the drain pump. This LINK explains.

Included is a follow-on link that explains how to check the drain pump to clean. You may also have to remove the inlet hose that runs from the bottom of the wash tub to the inlet side of the drain pump. Debris can commonly clog in this area as well causing the drain cycle to fail.

NOTE: If these preliminary measures do not correct your problem, you may have to replace the drain pump. It does not take much to damage the pump impeller or motor. Since the error code is generated if the drain cycle exceeds 8 minutes, if the pump is damaged and can't pump at the required volume, the error code will continue to appear until the pump is replaced.
If you need to open the door but it remains locked, you can first attempt to unplug the washer for at least 30 minutes in an attempt to reset the Central Control Unit (CCU). If the door remains locked, you can use the manual release to unlock and open the door. The LINK explains how.
NOTE: The Maytag Epic is manufactured by Whirlpool, so these procedures will apply to your washer.

you would need to go into the fault codes and read them. the tech sheet should be under the lid or in the kick panel
