Service and Disassembly Procedures
!WARNING
To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit and discharge capacitor through a 10,000 ohm resistor before attempting to service, unless test procedures require power to be connected. Ensure all ground wires are connected before certifying unit as repaired and/or operational.
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.
2.Turn off water supply to the Dishwasher.
3.Remove Support and Toe Panels. (See paragraph Front Support and Toe Panel removal).
4.Remove wires from Valve Solenoid.
5.Remove 2 1/4" screws securing Water Valve to Water Valve Bracket.
6.Disconnect injector hose at valve outlet.
