Possible Causes
Failed Hisense NTC temperature sensor, Loose or corroded NTC connector, Damaged wiring harness to NTC, Control board analog input fault
How to Fix / Troubleshooting
Safety first: Turn off power at the breaker before accessing the base or sump.
- 1. Locate the NTC sensor: The Hisense NTC is typically mounted in the sump or on the side of the tub base, often near the heater.
- 2. Inspect connector: Disconnect the NTC plug and check for corrosion, moisture, or loose pins. Dry and reconnect firmly.
- 3. Test sensor resistance: With a multimeter, measure the NTC resistance at room temperature. Compare to Hisense service specifications (commonly in the tens of kΩ). A reading of 0 Ω (short) or infinite (open) indicates a bad sensor.
- 4. Check wiring: Trace the harness from the NTC to the control board for cuts or pinched sections.
- 5. Replace NTC if defective: Remove the retaining clip or nut, swap in a new Hisense NTC sensor, and ensure a watertight seal.
- 6. If error persists: A faulty control board input may be misreading the sensor and will require board replacement by a professional.
