If your LG dishwasher displays an error code, it’s designed to alert you to a specific issue such as drainage problems, water supply faults, heating errors, or sensor issues. Understanding these codes can help you decide whether a simple reset is enough or if professional service is required.
Common LG Dishwasher Error Codes
OE – Drain error
The OE error means the dishwasher is not draining water properly at the end of a cycle.

This code indicates that the dishwasher is not filling with water as expected.
What you can try: Ensure the water tap is fully open and that household water pressure is normal.
When to call service: Ongoing filling issues may require a technician.
HE – Heating error
The HE error appears when the dishwasher cannot heat the water correctly.
What you can try: Turn the appliance off at the power for several minutes, then restart.
When to call service: Persistent heating errors usually indicate an internal component issue.

How to Clear an LG Dishwasher Error Code
