Diverter Motor - KitchenAid KUDE20FB*0 Technical Education

TESTING
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.

Diverter Motor

This test will check the wiring to the diverter motor and the
diverter motor itself. The following items are part of the
diverter motor circuit.
■ Harness/Connection
■ Diverter Motor
■ Diverter Position Switch (see test on following page)
■ Control Board
Test Procedure
1. Check for operation in Diagnostic Cycle. Listen for cam
clicking as it rotates—or inspect shaft with mirror to see
if rotating during diverter interval. If diverter is rotating,
the likely problem is with the diverter sensor (see test
procedure on following page). Verify that diverter disk is
properly installed on shaft.
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 diverter valve. Go to step 3.

3. Unplug dishwasher or disconnect power.
4. Remove outer door panel to access control board.
5. Unplug connector P7 from control board.
6. Check the diverter motor—using an ohmmeter, measure
the resistance between P7-4 and P7-6.
¾ If the resistance is between 1300-1600 ohms, the
diverter motor and harness are good. Go to step 7.
¾ If outside the range, replace the diverter assembly.
¾ If an open circuit is detected, check connections and
harness continuity between control and diverter
assembly. If good, replace the diverter assembly.
7. Reconnect P7 to control board.
8. Plug in dishwasher or reconnect power.
9. Check for AC voltage from the Control. Start the
Diagnostic Cycle and at the proper interval measure for AC
out of the control between P7-4 to P7-6 using a voltmeter
set to AC.
IMPORTANT: The Diverter 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 diverter is rotating, go to
step 10.
10. Perform Diagnostic Cycle to verify repair.
¾ If diverter error still exists, perform diverter sensor test
procedure on following page.
11. Unplug dishwasher or disconnect power.
12. Reassemble all parts and panels.
13. Plug in dishwasher or reconnect power.
