140000401012 Genuine Turbidity and Temperature Sensor for Electrolux Dishwashers, Dishwasher Water Clarity Sensor

Electrolux part 140000401012 is a combined temperature and turbidity sensor. In a dishwasher, the turbidity side measures how cloudy the wash water is, while the temperature side reports the water heat to the control board. This is the genuine part. Models aren't on our records, so confirm 140000401012 on your parts list or the old sensor before ordering.

Sensor faults on an Electrolux dishwasher

Auto and sensor programs rely on the turbidity reading to decide how long to wash and how many rinses to run. Cloudy water means more cleaning, clear water means the job is done. The temperature reading tells the board when the water is hot enough. A faulty sensor can make auto programs run far too long or finish early, leave dishes dirty, stop the heating working properly, or bring up a sensor fault code. Scale or a film of grease over the sensor window can cause similar symptoms, so clean it first. If the fault persists, the sensor is the likely culprit.

Fitting the sensor

Switch the dishwasher off at the wall and turn off the tap. The sensor usually mounts in the sump or a hose near the pump, so access is from underneath. Unplug the connector, then twist or unclip the sensor out, catching any water. Check the seal is in place on the new sensor, fit it firmly, reconnect the plug and run an auto program to test.

Questions about this part

What is a turbidity sensor?

It's an optical sensor that shines light through the wash water and measures how much gets through. Dirty water blocks more light, which tells the dishwasher to keep washing or add extra rinses.
