Possible Causes

Open or shorted NTC sensor, loose NTC connector, damaged wiring harness, moisture in sensor connection

How to Fix / Troubleshooting

Safety: Disconnect power before accessing internal components.

Steps:

  • Locate NTC sensor: On many Gaggenau dishwashers, the NTC is mounted in the sump or integrated with the heater/heat pump assembly.
  • Inspect connector: Check for corrosion or loose fit at the NTC plug. Clean and reseat.
  • Measure resistance: At room temperature, measure the NTC resistance and compare to the service chart. A reading of 0 Ω (short) or infinite (open) indicates a bad sensor.
  • Check harness: Follow the wiring from the NTC to the control module and look for damage or pinched sections.
  • Replace NTC sensor: If faulty, replace the NTC with the correct Gaggenau part. Ensure the sealing grommet is properly seated to prevent leaks.
