Steps:
- Unplug the dishwasher from the mains before any work begins.
- Never touch internal wiring with the appliance connected.
- Compare wash water temperature with program settings; unexpected cold cycles indicate a faulty sensor.
- Symptoms are almost identical to a failed heating element, so rule that out first.
- Look for the sensor near the heater on the tub floor in roughly ninety percent of models.
- If it is not on the tub floor, inspect the door panel because some machines place the sensor there.
- Most sensors are found underneath the tub, near the heating element, or inside the door. If you're unsure, check the device page of your specific model for diagrams.
- Unscrew or unclip the lower decorative plate to expose the sensor mounting area.
- Determine whether the part is a bimetal thermostat, an NTC probe, or a combined design used in some models.
- Expect an NTC probe to cost around fifteen euros depending on the spare‑parts supplier.
- Release the sensor clip and pull the sensor straight out of the housing.
- Keep the rubber gasket on the sensor for reference or reuse.
- Press the rubber gasket fully into the tub opening to prevent leaks.
- Push the new sensor into place until it locks flush with the gasket.
- Tighten the sensor retaining ring or fasteners evenly without over‑torquing.
- Reconnect the two sensor wires; polarity is irrelevant on NTC probes.
- For thermostat types match the colored dot or markings recorded during removal to keep correct orientation.
- Reattach the decorative plate and its fasteners to restore the dishwasher’s appearance.
- Restore power, run a short wash cycle, and confirm the appliance reaches the correct temperatures.
- Monitor for leaks around the sensor sealing area during the first cycle.
- If the machine still misbehaves, consult a qualified technician.
