Maintaining the Conductivity Sensor
The operation of the Conductivity Sensor may degrade if it becomes
contaminated with soil from glassware that has not been rinsed prior to being
placed into the washer or if it becomes coated with minerals from the water
supplied to the washer. If cleaning the sensor fails to correct the problem, the
sensor must be replaced. If the interior of the washer is discolored and appears to
be coated with a film, there is a good possibility that the conductivity sensor is
also coated. Follow the directions for removing film or spots from the washer
interior described previously in this chapter.
To clean the conductivity sensor:
If the soil from unrinsed glassware has coated the sensor, the sensor may be
cleaned using a solvent compatible with the soil. Remove the sump filter screw
as described previously in this chapter. Using a swab moistened with solvent,
remove the soil from metal parts inside the tubular portion.
To replace the conductivity sensor:
1.
Turn off the electrical power to the washer. Turn off the circuit breaker that
services the washer.
2.
Remove the cabinet back panel.
3.
Unplug the sensor from the harness.
4.
Unscrew the sensor from the sump housing.
5.
Reverse this procedure when installing a new sensor.
