FOR SERVICE TECHNICIAN'S USE ONLY
7. Resistance should be 12–20 Ω when the
pump is at room temperature.
 If the reading is infinite (open), go to step 8.
 If the reading is correct, go to step 12.
8. Remove the front panel to access drain
pump. Verify that pump, pump filter, drain
hose, and air trap are free from obstructions.
9. Visually check the electrical connections
at the drain pump.
 If visual check passes, go to step 10.
 If connections are loose, reconnect the
electrical connections and repeat step 2.
10. With an ohmmeter, check harness for
continuity between the drain pump and ACU.
 If there is continuity, go to step 11.
 If there is no continuity, replace the lower
machine harness and repeat step 2.
11. With an ohmmeter, measure the resistance
across the two pump terminals. Resistance
should be approximately 16 Ω.
 If the reading is infinite (open), replace the
drain pump assembly.
 If the reading is correct, go to step 12.
12. If the preceding steps did not correct the
drain problem, replace the ACU.
 Unplug washer or disconnect power.
 Replace the ACU.
 Reassemble all parts and panels.
 Perform the "Quick Diagnostic Test"
on page 6 to verify repair.
Water Temperature Controls
3 Heating Element – Test #9
3 Temperature Sensor – Test #10
TEST #9: Heating Element
(on some models)
This test checks the heating element, wiring,
and ACU.
1. Unplug washer or disconnect power.
2. Remove top panel to access machine
electronics.
3. Disconnect connector J15 from the ACU.
Refer to ACU diagram on page 13.
DO NOT REMOVE OR DESTROY
4. Using an ohmmeter, measure the resistance
across pins 1 and 2 of connector J15.
 If the resistance is 7-30 Ω, the heating
element and wiring are good; go to step 8.
 If the resistance is open, go to step 5.
5. Remove back panel to access the heating
element.
6. Disconnect the wire connectors from the
heating element. See Figure 8.
7. Using an ohmmeter, measure the
resistance across the two heating element
terminals.
 If the resistance is 7-30 Ω, the heating
element is good; replace the lower main
harness.
 If the resistance is open, replace the
heating element.
8. If the preceding steps did not correct the
heating element problem, replace the ACU.
 Unplug washer or disconnect power.
 Replace the ACU.
 Reassemble all parts and panels.
 Perform the "Quick Diagnostic Test"
on page 6 to verify repair.
