Problem: The wash heater is overheating. The temperature sensor detected heat above safe limits. This is either a bad sensor or a stuck heater relay.
How to Fix HC1 Error
- UNPLUG washer from electrical power. Wait 20 minutes for components to cool completely.
- Remove lower front access panel to expose heater assembly mounted on tub front.
- Disconnect electrical wires from heater terminals. Label wires for correct reconnection.
- Test heater element resistance with multimeter: set to resistance mode. Proper reading is 20-40Ω.
- If multimeter displays OL (infinite resistance), element has open circuit and must be replaced.
- Remove mounting bolts securing heater to tub (typically 2-3 bolts). Note gasket position.
- Extract old heater assembly. Clean tub mounting surface thoroughly with isopropyl alcohol.
- Install new heater assembly using OEM part DC97-14470A with new gasket. Torque mounting bolts to 15 ft-lbs in crisscross pattern.
- Reconnect wires securely. Reassemble access panel. Run sanitize cycle while monitoring for leaks and proper heating.
