Diverter Sensor/Position Switch - KitchenAid KUDE20FB*0 Technical Education

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 Sensor/Position Switch

This test will check the wiring to the diverter sensor/position
switch and the diverter assembly itself. The following items are
part of the diverter sensor/switch circuit.
■ Harness/Connection
■ Diverter Motor (see test on previous page)
■ Diverter Sensor/Position Switch
■ Control Board
Test Procedure
1. Check the operation of the diverter motor in the Service
Diagnostic Cycle. You should be able to "hear" the cam
clicking as it rotates through the following wash zones.
¾ Interval 20, the diverter motor is activated and water is
'diverted' to upper spray arm.
¾ Interval 11, the diverter motor is activated and water is
'diverted' to the Turbo Zone (some models only).
¾ Interval 10, the diverter motor is activated and water is
'diverted' to lower spray arm.

2. If the diverter is diverting the flow of water to the wash
zones, the diverter motor is working–continue to step 3.
If not, perform the diverter motor test procedure on the
preceding page.
3. Unplug dishwasher or disconnect power.
4. Remove access panel and outer door panel.
5. Visually check that the diverter position switch connector
and P11 connector on the control are securely installed.
¾ If visual check passes, go to step 6.
¾ If any of the connectors are not inserted properly,
reconnect and retest diverter position switch.
6. Check continuity of harness between diverter position
switch and P11 on control.
¾ If continuity test is good, continue to step 7.
¾ If continuity test fails, repair or replace harness as
needed.
7. To test diverter switch, unplug connector P11 from control
board and connect an ohmmeter across pins 3 and 4 (on
the connector removed, not the control board).
8. Plug in dishwasher or reconnect power.
9. Run the service diagnostic cycle as stated in Step 1, and
during Intervals 20, 11, and 10, you should observe the
diverter position switch closing momentarily and then
reopening as it reaches each potential position.
¾ If the switch is functioning normally (approximately 3
ohms or less when closed), proceed to step 10.
¾ If switch does not open or close properly, or resistance
is much greater 3 ohms when closed, then replace
diverter assembly and retest.
10. If all the previous tests pass, replace the control board.
11. Perform Diagnostic Cycle to verify repair.
12. Reassemble all parts and panels.
13. Plug in dishwasher or reconnect power.
