I'm getting an F29 Error on my WASH MACHINE and I've tried to power down several times, I've checked the incoming water (as I thought it might be version of the F20 error) and everything is ok there. Now we have a new issue of the DOOR being locked and can't get it to open. HELP 2707481285

The Whirlpool Duet F29 error code on that model washer is a door lock assembly failure error code. The door lock assembly will need to be replaced to repair the machine. The door lock assembly you need for that model can be ordered from the link below:

The video below shows how to replace it:

Until you get it repaired if you need to open the door for any reason you can it manually.

To open the door manually:

1. Unplug washer or disconnect power.
2. Remove the lower kick panel.
3. Reach up along the inside of the front and locate the bottom of the door switch/lock unit.
4. Located on the bottom of the door switch/lock unit is a tear-drop shaped tab.
5. Gently pull the tab down about a ¼” or until a click is heard.
6. The door should be opened.

Hope this information helps.
