KitchenAid Dishwasher Error Code DOOR OPEN

The DOOR OPEN error means the dishwasher control board is detecting that the door is either unlatched or was opened during an active cycle. The control board monitors the door latch switch continuously, and any open or incomplete latch signal will trigger this error. It can appear at startup if the door is not fully closed before pressing the cycle button, or mid-cycle if the door is pulled open. Closing and firmly latching the door is the first step to resolving it.

No, the dishwasher will not run a cycle while this error is active, which is intentional. Operating a dishwasher with an improperly latched door could result in water leaking onto the floor during the wash or drain cycle. The error is a protective condition, and the dishwasher should not be forced to operate until the door latches correctly.

If the issue is simply debris in the latch area, the fix costs nothing beyond your time. If the door latch assembly needs replacement, parts typically range from $20 to $60 depending on the specific model. Adding professional labor for diagnosis and installation generally brings the total repair cost to somewhere in the range of $100 to $200, though this varies by region and service provider.

Start by firmly pushing the door closed until you hear a distinct click from the latch, then attempt to restart the cycle. Check the latch strike area for any food debris or detergent buildup that might be blocking full engagement and clean it out if needed. If the error continues with the door securely closed, the door latch assembly or its wiring connection should be inspected for wear or damage, and the latch assembly may need to be replaced.

A reset alone will not clear this error if the underlying latch condition has not been resolved. The control board will re-detect the open or unlatched door as soon as a cycle is initiated. You need to ensure the door is physically latching correctly before a reset or restart will allow the cycle to proceed normally.
