Troubleshooting Common Error Codes On Your LG Dishwasher

If your LG dishwasher is showing an error code, it can feel a bit unsettling. After all, these codes often pop up when something's gone wrong with your appliance. But don't worry — many issues are relatively simple to fix with a little guidance. In this article, we'll walk through some of the most common error codes that might appear on your LG dishwasher's display and how you can troubleshoot them yourself before calling in a professional.

For instance, the "IE" error code usually indicates a problem with water intake. This could be a sign your dishwasher is too old, but it could also mean that the water valve is blocked, or that there's an issue with the water supply itself. If you encounter this, start by ensuring the dishwasher's water inlet valve isn't clogged. Check the hose for any kinks or bends that may be restricting water flow, and verify that the water supply to your home is turned on properly.

Another frequent error code is "OE", which signals an issue with drainage. This typically happens when the dishwasher has trouble draining the water at the end of a cycle. The cause could be a clogged filter or a blocked drain hose. To fix a dishwasher that isn't draining, check the filter in the bottom of the dishwasher for any debris or food particles. If the filter is clean, the next step is to inspect the drain hose for blockages. If both the filter and hose are clear and the error persists, you may need to inspect the pump itself for potential issues.

If your dishwasher is showing the "HE" error code, it indicates that there is an issue with the heater. This could be caused either by the inability to heat the water or the overheating of the water. To fix this problem, you should turn off the dishwasher and then turn off the circuit breaker for the dishwasher. Give it at least 10 seconds before turning it back on again. If the code doesn't go away, you'll need to call the service team.

The error code "AE," which may also display as "E1," likely means a leak inside the dishwasher. The leak triggers the dishwasher's float switch, which activates the flood protection device. To repair the leak, you must first locate it. Inspect the door gasket, spray arms, water valve, hose, water fill line, drain pump, and drain hose to try to pinpoint the leak. Scrub out any buildup that may be affecting seals, and if that doesn't help, contact the repair team, as they may have to replace the hose on your dishwasher. 

Lastly, the "LE" error code often signals a motor problem or a failure in the motor's communication with the control board. In such cases, a reset of the dishwasher may help. However, if the problem persists after a reset, you might be dealing with a more serious issue that requires professional attention. Sometimes, the control board or the motor might need to be replaced to resolve the issue completely.
