About LG dishwasher error codes

LG Electronics is a South Korean manufacturer and one of the best-selling appliance brands in the US. LG appliances show short letter-and-number codes on the main control panel, and many recent models can also report them to the LG ThinQ app.

Of the 16 codes on this page, 5 usually have a simple fix you can do yourself, and 7 usually need a technician. Each guide tells you which is which, so you don't pay for a service call you don't need, and you don't attempt a repair that isn't safe.

Before you start

• Write down your model number. It's on a sticker, usually inside the door or lid, on the frame, or on the back or side panel. Parts and some code meanings depend on it.
• Try a reset. Unplug the dishwasher or switch off its breaker for 10 minutes. This clears many one-off glitches without tools.
• Clean the filter at the bottom of the tub. A clogged filter is behind many drain and wash codes.
