Bosch Dishwasher Error Code DOOR OPEN

The DOOR OPEN error means the dishwasher's control board did not receive confirmation from the door latch switch that the door was fully secured within the required time after a cycle was started. The machine halts as a safety measure to prevent operating with an unsecured door. This can be caused by user error, a worn latch, a failed switch, or a wiring problem.

No. The dishwasher is designed to prevent operation when it cannot confirm the door is latched. Running the machine with an improperly secured door could result in water leaking onto your floor. Do not attempt to bypass or override this safety feature, and resolve the underlying cause before running a cycle.

If the fix is simply closing the door properly, there is no cost involved. Replacing a door latch assembly or door latch switch typically ranges from $20 to $80 in parts depending on the model, plus labor if you hire a technician. A full service call from a professional appliance repair technician generally runs between $100 and $250 including diagnosis and parts for this type of repair.

Start by firmly pushing the door closed until you hear and feel the latch click. If the error persists, access the Switch submenu in the Service Menu to check whether the control board is registering the door switch state. If the switch reading does not change when you manually operate the latch, the latch assembly or door switch likely needs replacement. Also inspect the door hinge alignment and wiring harness for visible damage.

A reset will clear the error from the display, but the code will return immediately when you attempt to start a new cycle if the underlying problem has not been fixed. The control board checks door status at the start of every cycle, so the fault will reappear until the latch, switch, or wiring issue is resolved.
