LG Dishwasher Error Code dE
The machine will not start because, as far as its door switch is concerned, the door is not properly shut. Most of the time something simple is in the way — a rack pushed back crooked or a pan handle stopping the door the last few millimetres. Push the door firmly and check for obstructions before blaming the latch.
Common causes
- Door not pushed fully closed
- Rack or tall item protruding and holding the door off its seal
- Worn, broken or misaligned door latch
- Failed door switch
What to check, in order
- Open the door, slide both racks in fully, and check nothing sticks out past the tub opening
- Close the door with a firm push until the latch clicks, and try starting again
- Look at the latch on the door and the catch on the frame for cracks, bent parts or trapped debris, and clean what you find
- If the latch looks sound but the code stays, the door switch needs testing — a technician's job
Clear the code and test
- Fix what the checks above found first — a filter cleaned, a hose straightened, the spray arms freed. Clearing the code without fixing the cause only brings it back.
- Close the door, plug the dishwasher back in (or restore its breaker) and make sure the water tap is open.
- Run the shortest programme and stay nearby for the first minutes, watching for leaks and listening for the drain pump.
- If the programme finishes with no code, the fault is cleared. If the code returns, write down the code and when it appeared before calling a technician — it speeds up the diagnosis.
When to call a professional
Most cases are solved by the checks above. Book a technician if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code dE, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
