H0120400076 Genuine Temperature and Turbidity Sensor for Fisher & Paykel, Haier Dishwashers, Water Clarity Sensor

This is the genuine combined temperature and turbidity sensor H0120400076, used in Fisher & Paykel and Haier dishwashers. One part does two jobs, reading water temperature and how cloudy the wash water is. We don't have a model list on file for it. Compare it with the number on your old sensor, or send your dishwasher's model and serial number through the parts enquiry form and we'll check.

How a turbidity sensor affects dishwasher cleaning

Auto and sensor programs shine light through the wash water to judge how dirty it is, then add or skip rinses and adjust run time to suit. The same sensor reads water temperature so the heater can bring the wash up to the right level. A faulty sensor can make auto cycles far too short or far too long, leave dishes dirty or not hot enough to dry, or bring up heating or sensor error codes. A film of grease or limescale on the sensor can mimic a fault, so clean the filters and sump area first.

Fitting the sensor

Switch off at the wall and turn off the water tap. In most dishwashers this type of sensor sits in the sump or pump area under the tub, so lay the machine on its back or side on towels to reach it. Photograph the plug, swap the sensor, and make sure its seal is seated so it can't leak. Run an auto program to confirm the fault has cleared.

Questions about this part

Do I need a technician to fit this?

A handy home owner can often fit it, but you'll need to get under the dishwasher and deal with water and wiring. If you're not comfortable with that, have a qualified appliance technician do the job.
