Possible Causes

Open or shorted NTC sensor, Loose NTC connector, Damaged wiring between NTC and PCB, PCB analog input fault

How to Fix / Troubleshooting

Safety first: Unplug the washer.

Locate the NTC sensor:

  • Access the heater area at the bottom of the tub from the rear or front lower panel.
  • The NTC is usually clipped into the heater bracket or inserted into the tub wall.

Test the NTC:

  • Disconnect the NTC connector.
  • Measure resistance at room temperature; typical values are 15–25 kΩ. Warm the sensor slightly with your hand; resistance should decrease smoothly.
  • If reading is infinite, near zero, or unstable, replace the NTC sensor.

Check wiring:

  • Inspect the harness from NTC to PCB for cuts or corrosion and reseat connectors.

Reassemble and run a hot wash. If D12 persists with a new NTC and good wiring, the PCB input circuit is likely defective.
