LG Dishwasher Error Code dE

The dE code on an LG dishwasher stands for a door open warning. It means the dishwasher detected that the door was open or unlatched during an active wash cycle and stopped operation as a result. The appliance monitors the door latch switch continuously while running, and any loss of the closed-door signal will trigger this code.

A reset can clear the dE code temporarily, but it will return if the underlying cause has not been addressed. To reset, press the Power button to turn the unit off, wait about 10 seconds, and power it back on. If the door latch or switch is defective, the code will reappear as soon as a new cycle is started.

If the fix is simply repositioning a rack or closing the door properly, the cost is nothing. Replacing a door latch switch or latch assembly typically costs between $20 and $80 for the part, with professional labor adding $75 to $150 depending on your location. Door hinge adjustments or gasket replacements generally fall in a similar part cost range.

Start by firmly closing the door until you hear an audible click, then attempt to restart the cycle. Check that no dishes, racks, or utensils are blocking the door from closing fully. If the error returns, inspect the door gasket for damage and the latch mechanism for wear or debris. A persistently faulty door latch switch will need to be replaced to resolve the code.

The dE code is a protective shutoff, meaning the dishwasher has already stopped the cycle to prevent water from spraying out of an open door. Do not attempt to force or bypass the cycle while the door is not fully secured. Address the door latch issue before running another cycle to avoid potential water damage inside the cabinet.
