Possible Causes
Faulty hall sensor on wash motor, Wiring issue to sensor, Faulty heater sensor, Main PCB misreading sensor
How to Fix / Troubleshooting
Safety first: Disconnect power at the breaker.
- Identify HS meaning: Check your model's service documentation; on many LG dishwashers HS refers to a hall sensor on the circulation motor.
- Inspect motor sensor connector: Access the underside of the dishwasher and locate the wash motor. Check the small sensor connector (hall sensor) for loose fit or corrosion. Reseat firmly.
- Check wiring harness: Follow the harness from the motor to the main PCB, looking for damage or pinched wires.
If HS persists, the circulation motor assembly (with hall sensor) or the main control board may need replacement. This repair is typically best handled by a technician.
