For Service Technician Use Only
DANGER
Electrical Shock Hazard
Only authorized technicians should perform
diagnostic voltage measurements.
After performing voltage measurements,
disconnect power before servicing.
Failure to follow these instructions can result in
death or electrical shock.
Dispenser Circuit
This test will check the wiring to the dispenser and the
dispenser solenoid or wax motor itself. The following items
are part of the dispenser circuit.
■ Harness/Connecon
■ Dispenser Solenoid/Wax Motor
■ Control Board
Test Procedure
1. Check for obstrucons or mechanical binding prevenng
the dispenser lid from opening. Repair or replace as
necessary.
2. Are all the loads controlled by TRIACS not working?
¾ YES – check for open door switch, TRIAC fuse, or pilot
relay.
¾ NO – just the Fill Valve. Go to step 3.
3. Unplug dishwasher or disconnect power.
Strip Circuit – Dispenser
4. Remove outer door panel to access control board.
5. Unplug connector P9 from control board.
6. Check the dispenser solenoid or wax motor (depending
on model) and harness—using an ohmmeter, measure the
resistance between P9-1 and P9-3.
Solenoid:
¾ If the resistance is between 280-340 ohms, the
solenoid valve and harness are good. Go to step 7.
¾ If outside the range, replace the dispenser solenoid.
¾ If an open circuit is detected, check connecons and
harness connuity between control and dispenser. If
good, replace the dispenser solenoid.
Wax Motor:
¾ If the resistance is between 1.4-2.8k ohms, the wax
motor and harness are good. Go to step 7.
¾ If outside the range, replace the dispenser wax motor.
¾ If an open circuit is detected, check connecons and
harness connuity between control and dispenser. If
good, replace the dispenser wax motor.
7. Reconnect P9 to control board.
8. Plug in dishwasher or reconnect power.
9. Check for AC voltage from the Control. Start the
Diagnosc Cycle and at the proper interval measure for AC
out of the control between P9-1 to P9-3 using a voltmeter
set to AC.
IMPORTANT: The Dispenser Solenoid or Wax Motor must
be connected to the control board to measure voltage
accurately!!!
¾ If no AC voltage is measured, replace the control board
and retest.
¾ If 120V AC is measured and dispenser motor is
energized, go to step 10.
10. Perform Diagnosc Cycle to verify repair.
11. Unplug dishwasher or disconnect power.
12. Reassemble all parts and panels.
13. Plug in dishwasher or reconnect power.
