Short answerLG uses short letter codes — OE for drain, IE for inlet, dE for door — and the same code often appears on washers and dishwashers. Newer LG washers may show a number instead (OE = E03 / E21). Find your code below, try LG's fix, and check the listed part only if it keeps coming back.
How to reset an LG appliance
- Washer / dryer: power off and unplug (or trip the breaker), hold START/PAUSE for 5 seconds, restore power and restart.
- Refrigerator: unplug about 5 minutes. For defrost or ice codes, remove the food and leave the doors open at least 12 hours.
- Range: press CLEAR/OFF, or switch the breaker off and on.
- Smart Diagnosis: in the ThinQ app, open the appliance → ⋮ → Smart Diagnosis.
