LG Dishwasher Repair – Bowerston, OH (LDs5540st)

A customer in Bowerston called about their LG dishwasher displaying an HE error code and not heating the water properly. The dishwasher display flashes HE and the dishes don’t get hot. Our initial repair attempt involved replacing the heating element and thermistor sensor, but the issue persisted and required additional troubleshooting.

The Problem

The dishwasher display flashes HE and the dishes don’t get hot. This HE error code on LG dishwashers typically indicates a heating system malfunction, preventing the unit from reaching proper wash temperatures.

Diagnosis

Our technician diagnosed the issue as a faulty heating element and thermistor sensor. These components work together to heat the wash water and monitor temperature throughout the cycle.

The Repair

• Parts replaced: Heat element and thermistor sensor
• Work performed: Replaced the heat element / Thermistor sensor
• Result: The repair was unsuccessful. I mailed a refund check for the part

Is It Worth Repairing?

LG dishwashers are generally reliable appliances, but heating system problems can sometimes involve multiple components or control board issues. When a straightforward part replacement doesn’t resolve the problem, it may indicate a more complex electrical issue that could make the repair less cost-effective than replacement.

Maintenance Tips for LG Dishwashers

• Run hot water at your kitchen sink before starting the dishwasher to ensure proper inlet temperature
• Clean the dishwasher filter monthly to prevent debris from affecting heating elements
• Use rinse aid to improve drying performance and reduce spots on dishes
