TROUBLESHOOTING TESTS

TEST #1: Main Control
This test checks for incoming and outgoing power
to and from main control. This test assumes that
proper voltage is present at the outlet.
1. Unplug washer or disconnect power.
2. Remove console to access main control.
3. Verify that ALL connectors are inserted
all the way into the main control.
4. Plug in washer or reconnect power.
5. With a voltmeter set to AC, connect black
probe to J7-3 (Neutral) and red probe to J7-1 (L1).
 If 120VAC is present, go to step 6.
 I f 120VAC is not present, check the AC power
cord for continuity (See Figure 9, page 20.)

6. Is the "Diagnostic LED" ON or OFF? (See
Figure 3 below for LED location.)
 ON: (+5VDC present) continue to step 7.
 OFF: (+5VDC missing) proceed to step 8.
7. With a voltmeter set to DC, connect black
probe to J9-3 (Circuit Gnd) and red probe to
J9-8 (+13VDC).
 If +13VDC (and +5VDC) are present, and
UI is unresponsive, go to Test #4: Console
and Indicators, page 16.
 If +13VDC is not present, go to step 8.
8. Check if shifter assembly is affecting the
main control DC supplies.
a. Unplug washer or disconnect power.
b. Remove connector J2 from main control.
c. Plug in washer or reconnect power.
