•
Check the line filter connection terminals for
good connections.
•
Check the machine control board terminal
connections AC1-CN7 (Pin 2) White to AC2-
CN5 Black for good connections.
•
Check for stuck buttons on console, pushing
in on board tact switches. Readjust buttons
on inside of console.
•
Replace console control board
.
Leaking
•
Make sure inlet hose connections are not
leaking. Check for rubber gasket damage due
to over-tightening.
•
Check standpipe for leak. Wrap a dry rag
around the standpipe opening. If rag becomes
wet, leak is fault of home plumbing. Be sure
the standpipe is capable of accepting the flow
of water from the washer.
•
Make sure end of drain hose is correctly
inserted and secured to drain standpipe.
•
Check internal hose connections (fill, drain
systems, dispenser hoses & clamps).
•
Check rubber boot. Remove, reposition and
reinstall, if necessary.
•
Check for possible kinked dispenser to outer
tub hose. Hot water pressurization may force
door open.
No Tumble
•
Start normal cycle with an empty machine and
allow a fill to check tumble.
•
Washer does not tumble during most fills or
during presoak.
•
Perform
Board Output Test
.
•
Check for loose connections at machine
control board, pressure switch, motor, tach
harness and motor control.
•
Check motor windings resistance. (Pins 8 & 9
= 3.6 ohms, pins 1 & 10 = 1.1 ohms, Pins 5 &
10 = 1.1 ohms)
•
Check belt.
Will Not Spin
•

previously.
•
Check for loose connections at machine
control board, pressure switch, motor, tach
harness and motor control.
•
Check belt.
No Water Fill
•
Test water fill. Perform
Board Output Test
.
•

water valve, and pressure switch.
•
Check for kinks in inlet hoses.
•
Check for clogged inlet screens.
•
Visually check hot and cold separately for fill.
•
Check for low water pressure. May be
dependent on pressure entering home.
Variations may occur due to usage in the
home at the time machine is used.
•
Check for frozen pipes and hoses.
•
Check resistance of water valve coils. (normal
1.18K ohms; CN3 connector – Cold (BU) –
Bleach (OR) – Hot (RD)
•
Check for loose connections at the pressure
switch or on the machine control board,
connector 5P.
Tub Full of Suds
•
Check for restricted drain system. See
Will
Not Drain and Will Not Spin.
•
Check for loose wire connections at control
board and pump.
•
Perform
Board Output Test
.
•
Use high efficiency or low sudsing detergent
specially formulated for front load washers.
•
Reduce detergent amount for that specific
load size and soil level. Towel loads have a
minimal amount of soil present and typically
