TEST #8: Drum LED
This test is performed if the drum LED does
not light.
1. Unplug dryer or disconnect power.
2. Remove the console to access ACU
and user interface (UI).
3. Verify that the drum LED connector J20
(see wiring diagrams, pages 25 and 26)
is securely connected to the UI.
4. Check harness and inline connections
between the drum LED and UI.
 If the harness and connections are good,
go to step 5.
 If not, repair or replace as needed.
5. Unplug the drum LED connector J20
(see wiring diagrams, pages 25 and 26)
from the UI.
6. With a multimeter set to milliamps, connect
multimeter to UI connector J20, pins 1 and
3. Plug in dryer or reconnect power. Open
the door. Measure the current across UI
connector J20, pins 1 and 3. If the drum LED
driver is working properly, there should be a
measurement of 150 mA.
 If the current is present, unplug dryer or
disconnect power and replace the drum LED.
 If the current is not present, unplug dryer
or disconnect power and replace the UI.
7. Reassemble all parts and panels.
TEST #9: Water Valve
(on some models)
Activate Service Test Mode (see page 6).
Skip to Step 8 in Service Test Mode Chart (see
page 8). Verify that water is being sprayed into
the drum. See figure 12.
NOTE: Refer to strip circuit on page 24 to
diagnose water valve.
If water leaks from the dryer/too much water
being sprayed into the drum:
1. Inside the drum, unscrew the water nozzle.
2. Inspect nozzle opening for residue buildup;
clean and replace it.
If no water is sprayed in the drum:
1. Verify that water is connected and turned on.
2. Unplug dryer or disconnect power.
3. Remove console to access the machine
electronics.
DO NOT REMOVE OR DESTROY
4. Verify that the red wire coming from the
water valve is connected to the ACU, P8-1.
Refer to wiring diagrams on pages 25 and 26.
Water Valve Assembly
Figure 12 - Water System Components.
5. Check Water Valve & Harness—using an
ohmmeter, measure the resistance between
the ACU P8-1 (red wire) and P9-2 (black wire).
 If the resistance is 1300 Ω (±5%), go to
step 6; if not, replace the water valve.
 If an open circuit is detected, go to step 7.
6. Inside the drum, unscrew and replace the
water nozzle using a 7/16" wrench or socket.
Retest water valve.
 If water does not dispense, go to step 7.
7. Access the water valve by removing the
back panel.
 Check that the hose and wires are connected
to the water valve assembly (see figure 12).
 Check that the water valve assembly hose
is connected to the nozzle.
8. If everything is connected and the water
still does not dispense:
 Unplug dryer or disconnect power.
 Replace the valve assembly and retest.
9. If the preceding steps did not correct
the problem, replace the ACU.
