Accompanying symptoms may include unusual noises during operation and the inability to drain water effectively.

Common Symptoms:

  • Dishwasher displays C7 on the control panel
  • Cycle may end early or skip heating/drying functions
  • Dishwasher unable to properly regulate water temperature

Possible Causes

  • Faulty or open/shorted temperature sensor (thermistor) (high)
  • Loose or corroded wiring/connectors between thermistor and control board (medium)
  • Control board input circuit for temperature sensor is defective (medium)

  1. Turn off power at the breaker.
  2. Access the sump area or sensor location where the thermistor is mounted.
  3. Inspect the wiring harness and connector for corrosion, damage, or loose pins.
  4. Use a multimeter to test thermistor resistance against manufacturer specifications at room temperature.
  5. Check continuity of wiring from the thermistor to the control board.
  6. Replace the thermistor if out of specification.
  7. If wiring and sensor are good but error persists, test or replace the control board’s sensor input circuit.

Parts needed: Temperature sensor (thermistor), Wiring harness/connector, Control board
