TROUBLESHOOTING TESTS

TEST #1: Main Control
This test checks for incoming and outgoing supplies to and
from the 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).

 I f 120VAC is present, go to step 6.
 I f 120VAC is not present, check the AC power cord
for continuity (See Figure 9).
6. Is the "Diagnostic LED" ON or OFF? (See Figure 3 below
for LED location.)
 O N: (+5VDC present) continue to step 7.
 O FF: (+5VDC missing) proceed to step 8.
7. With a voltmeter set to DC, connect black probe to J2-3
(Circuit Gnd) and red probe to J2-4 (+13VDC).
 If +13VDC is present, main control supplies are good.
 If +13VDC is not present, go to step 8.
