Possible Causes

Open or shorted NTC sensor, Corroded NTC connector, Damaged wiring harness, Control board sensing circuit fault

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before accessing internal components.

  • Reset and test: After a 10-minute power-off reset, run a short program and see if the error reappears.
  • Check connections: Access the base and locate the NTC sensor (often integrated into the heater or sump). Ensure the plug is firmly seated and free of corrosion or moisture.
  • Inspect harness: Look for pinched or damaged wires between the NTC and the main control board.

If the wiring and connector are intact, the NTC temperature sensor is likely defective and should be replaced. If a new sensor does not resolve the issue, the main control board may be at fault and requires professional diagnosis.
