Thermostats
Two types of thermostats are used in the Dishwasher. A
Thermistor and a Limit Thermostat.
The Thermistor is used to sense water temperature when
certain cycles or options are selected (Refer to Cycles &
Options section). The Thermistor is part of the sensor
mounted in the Tub.
The other thermostat is a Limit Thermostat and is used as
a protective device to sense overheating of the Heating
Element. It is located behind the Front Support and Toe
Panel. The limit is mounted to the tub bottom. This
thermostat has ¼" terminals and has a normally CLOSED
position.
NOTE: Refer to section labeled Technical Data for
specifications on thermostat.
Removal
1. Disconnect power to the machine.
2. Remove Front Support and Toe Panel. (See paragraph
Front Support and Toe Panel removal).
3. Press down on spring clip to release from Tub and
rotate till clip unlocks.
4. Remove wires from thermostat.
NOTE: When reinstalling, proper location and wiring of
thermostat(s) is critical.
Water Valve
The valve is located behind the Support and Toe Panel,
mounted to the left side of the Tub Support. Inlet water
supply to the valve is directly below the valve.
NOTE: Turn off water supply to the Dishwasher before
servicing this component.
The valve is designed to operate at water pressures of 15 -
120 psi.
NOTE: Low water pressure will affect the ability of the
Water Valve to properly fill Tub in the required
amount of time.
Incoming water temperature should be a minimum of 120
degrees F. However, a higher water temperature will
enhance washing and drying results.
Removal
1. Disconnect power to the machine.

Front Support and Toe Panel removal).
4. Remove wires from Valve Solenoid.
