Thermistor

The Thermistor is located inside the turbidity sensor.
The thermistor monitors water temperature in the

tub. If the thermistor opens or shorts it will cause an
error (see Consumer Error Mode). If it fails in open or
shorted, the control will default to the longest time
algorithm.

circulation time that the control is programmed for.
Use Diagnostic Fault Code Display Mode to look for

Turbidity Sensor Faults.

To check the thermistor, access the Main Control

(see To Access Main Control Board section), check
resistance on connector J711, pin 7, YR to pin 10,
WG. The sensor may also be removed and the two
outside terminals may be checked. Use the table to
the left to calculate the correct resistance reading.

Turbidity Sensor Removal

To remove the sensor, empty the sump of water.

Disconnect the wire harness, turn the sensor
counter-clockwise and pull from the sump. To
reinstall, push in and turn clockwise.
