3
None of the LEDs light up
3
One or more Status LEDs are flashing
3
Turning rotary switch does not toggle LED
None of the LEDs light up:
1.
Unplug washer or disconnect power.
2. Access the main control and visually check that ALL
connectors are inserted all the way into their respective
headers.
3.
Visually check that the main control assembly is properly
inserted in the console.
4.
If both visual checks pass, follow procedure under TEST #1,
“Main Control” on page 12 to verify supply voltages.
5.
To verify repair, activate the Service Diagnostic Mode, and
then perform UI Test Mode on page 4.
One or more Status LEDs are flashing:
If one or more of the status LEDs are flashing (on and off in
0.5 second intervals), refer to the following notes to identify the
switch(es) in question. Reference the wiring diagram on page 20
when performing the following procedures.

TEST #5: Temperature Thermistor
This test checks valves, main control, temperature thermistor,
and wiring.
1.
Check the cold valve by performing Cold Valve test under
Manual Overview Test Mode on page 9.

If cold water is being dispensed, proceed to step 2.
 If hot water is being dispensed, verify proper hose
connection.
2.
Check the hot valve by performing Hot Valve test
under Manual Overview Test Mode on page 9.

If hot water is being dispensed, proceed to step 3.
 If cold water is being dispensed, ensure that household
hot water is present.
3.
Unplug washer or disconnect power.
4. Remove console to access main control.
5. Remove connector J3 from the main control. With an
ohmmeter, measure the resistance of the temperature
thermistor between pins J3-9 and J3-10. V
erify that the
approximate resistance, shown in the following table,
is within ambient temperature range.
