When power is removed, the pivot arm spring forces
the pin to the bottom of the slot. A leaf spring pushes
the rinse aid injector pump arm to the left so that the pin
returns to the original starting position.

To test the dispenser:
1. Select Light Wash on selector switch and turn timer
to detent for Light Wash. Close and latch door.
2. Attach voltmeter to wax motor actuator. After timer
advances through drain and fill, it should read 120
volts as power is applied to actuator. Detergent
dispenser cup cover should open within 30
seconds.
3. Make sure pivot arm raises completely for pin to
move from back to front of rinse aid injector pump
arm. After power is removed, pivot arm should
return to bottom by slot in front of rinse aid injector
pump arm.
This test can be done with power from the dishwasher
or by using a test cord and connecting the wax motor
actuator to a 120 VAC power source. Remember to
remove power when the actuator is fully extended.
WATER FILL VALVE
The water valve is timer controlled and solenoid
operated. The flow of water is controlled by a rubber
flow washer capable of maintaining a flow rate of .83
gallons per minute with incoming water pressure of 20
to 120 P.S.I.
To Test the Water Valve:
1. Disconnect dishwasher from power supply.
2. Remove screws securing bottom service panel and
remove panel.
3. Remove electrical leads from valve and check
solenoid with an ohmmeter. See the Product
Specifications for your model for the correct reading.
4. To check for operation, connect a separate 120VAC
cord to valve and connect a ground to frame. Apply
power for a few seconds and then remove power.
The water flow should stop within 2 seconds. If not,
replace valve.
No Water in the Tub:
1. Be sure main water supply and electrical power is
turned on.
2. Check float assembly for free movement up and
down.
3. Remove service panel.
4. Advance timer to fill position and latch door. Start
dishwasher.
5. Check voltage to fill valve solenoid.
6. If voltage is present, disconnect power and measure
resistance of solenoid coil. The resistance on this
coil should be between 998 and 1188 ohms. If
solenoid coil proves to be bad, replace valve.
7. If solenoid checks good, turn off water supply and
electrical power to dishwasher. Remove water line
from valve and check screen for debris. Clean
screen and reassemble.
8. If there is no power to solenoid, check float switch,
timer , door switch, or appropriate wiring harness.
