LG Dishwasher Error Code OE
At the end of a drain step the water level was still too high, so the machine stopped rather than carry on with dirty water inside. The usual culprits are a clogged filter, food debris in the sump, or a drain hose that is kinked or blocked where it meets the sink plumbing. Standing water in the bottom of the tub is the giveaway.
Common causes
- Tub filter clogged with food debris
- Drain hose kinked, crushed or frozen
- Blocked air gap or garbage disposal connection at the sink
- Debris jamming the drain pump impeller
- Failed drain pump
What to check, in order
- Remove and rinse the filter in the bottom of the tub under a tap
- Check the drain hose along its whole run for kinks or crushed sections
- If the machine connects to a garbage disposal, make sure the disposal is clear and its drain knockout plug was removed at installation
- Look and feel in the sump (with power off) for glass, bones or labels jamming the pump area, and remove what you find
- If the pump only hums or stays silent when it should drain, have the drain pump tested and replaced if needed
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 OE, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
