LG Dishwasher Codes

LG dishwashers are known for their reliability, efficiency, and advanced technology. Like all appliances, however, LG dishwashers can sometimes encounter issues that need to be addressed. In these cases, LG dishwashers are designed to display error codes to help users diagnose and troubleshoot the problem.

Here’s a guide to all the LG dishwasher codes you may encounter, what they mean, and what you can do to fix them:

1. OE – Drain Error: The OE error code on LG dishwashers indicates that there is a problem with the dishwasher’s drainage system. It can be caused by a clogged or blocked drain hose, a defective drain pump, or a problem with the dishwasher’s control board. To resolve this issue, you can check the drain hose and pump for any obstructions, clean the filters, and reset the dishwasher. If the problem persists, you may need to call a professional technician.
2. LE – Motor Error: The LE error code on LG dishwashers indicates a problem with the dishwasher’s motor. This can be caused by a damaged or defective motor, a problem with the wiring or connections, or a fault in the dishwasher’s control board. To troubleshoot this issue, you can try resetting the dishwasher, checking the motor wiring and connections, and testing the motor for continuity. If none of these steps resolve the issue, you may need to call a professional technician.
3. HE – Heating Error: The HE error code on LG dishwashers indicates a problem with the dishwasher’s heating system. This can be caused by a faulty heating element, a defective temperature sensor, or a problem with the control board.

If the problem persists, you may need to call a professional technician.
4. FE – Water Inlet Error: The FE error code on LG dishwashers indicates a problem with the dishwasher’s water inlet system.
