How to Reset an LG Dishwasher

Resetting an LG dishwasher is pretty straightforward. To reset an LG dishwasher, you will have to cut off the electricity that goes to its main board. Unfortunately, LG dishwashers do not come with a dedicated reset button, so you will have to do it the old-fashioned way—i.e., unplug the device and plug it back in.

Here’s what you need to do to reset your LG dishwasher.

Press and hold the power button until the Dishwasher turns off—Before resetting your Dishwasher, ensure the device is turn off. Consult the instruction manual to figure out how to turn the device off, or you can press the start or power button until the lights on the control board turn off. Make sure the device is off before proceeding to the next step.

Unplug the Dishwasher from the wall receptacle or turn off the circuit breaker—After you’re confident that the Dishwasher is turn off, pull it forward and away from the wall to unplug the power cord. If the Dishwasher is hardwire to your home’s electrical system, go to the fuse box and switch off the circuit breaker to the Dishwasher.

Wait for 10 to 30 seconds—When you have cut the power to the Dishwasher, it will take a few moments to clear its memory cache. The manual of most LG dishwashers will advise leaving the device unplugged for 10 seconds when resetting it, but it doesn’t hurt to go slightly longer, just to be safe.

Restore power to the Dishwasher—After 10 to 30 seconds and elapsed, restore power to your Dishwasher by plugging it back into the wall receptacle or turning on the circuit breaker.

Run a test cycle to ensure everything is working—Press and hold the power button until the control board’s lights turn back on. Now, try running a quick wash cycle to ensure it is in working order.

And just like that, you have successfully reset your LG dishwasher! This method works for dishwashers from all brands, too.
