Symptom Probable Cause Suggested Remedy
Door will
not open
Door Rod Check to see that door rod from solenoid to lock ass’y is
long enough to allow lock ass’y to disengage. If not, adjust
rod.
Door Lock Sole-
noid
Check that door lock solenoid is not stuck closed. If stuck,
replace solenoid.
No hot
water in
detergent
dispenser
Water Valve Coil Check coil continuity at terminals and replace if no continu-
ity. 120 V power only on for 20 second in wash bath.
Water Inlet Check water inlet screens for blockage and clean screens if
necessary.
Water Check to insure that water is turned on and operating.
P-20 Wire Harness Check black & white harness.
Symptom Probable Cause Suggested Remedy
Hot water
does not
enter tub in
wash
Water Valve Coil Check coil continuity at terminals and replace if no continu-
ity. Check for 120 V power from main relay PCB
Water Inlet Check water inlet screens for blockage and clean if neces-
sary screens
Water Check to insure that water is turned on and operating.
Blk or Wht wire at
main controller
Check black or white wires at Molex plug on PCB at main
controller and at relay PCB.
Pressure Switch Check pressure switch continuity between terminals . If no
continuity, check pressure switch hose for obstruction. If
hose okay, change pressure switch.
No cold
water to tub
in wash
Water Valve Coil Check coil continuity at terminals and replace if no continu-
ity.
Water Inlet
Screens
Check water inlet screens for blockage and clean if neces-
sary.
Water Check to insure that water is turned on and operating.
Blk or whit wire
at controller and
main relay PCB
Check black or white wires at Molex plug on PCB at main
controller and at relay PCB.
Pressure Switch Check pressure switch continuity between terminal contacts.
If no continuity, check pressure switch hose for obstruction.
If hose okay, change pressure switch.
Water
comes in
but level
does not
rise
Drain Valve (open) Check these areas • Drain valve blockage • Drain valve mo-
tor and gear train. If power but drain valve does not close,
replace valve. • Power to the drain valve. If no power to
drain valve, check (brn/yel) circuit for power.
Blk or whit wire at
controller
Check black and white wires at molex plug on main PCB
controller and at main relay PCB
Water does

ment.
Water Valve Coil Check coil continuity at terminals and replace if no continu-
ity.
Water Inlet

Check water inlet screens for blockage and clean if neces-
sary.
Water Check to insure that water is turned on and operating.
Symptom Probable Cause Suggested Remedy
Water does

compart-
ment.
Pressure Switch Check pressure switch continuity between terminals. If no
continuity, check pressure switch hose for obstruction. If
hose okay, change pressure switch.
Water level
too high
Pressure Switch Check for blockage in pressure switch hose. Check for
pressure switch opening circuit across terminals . Replace
switch if contacts do not open.
Water
drains
slowly
Drain System Check hoses and drain valve for blockage. Clean of inad-
equate size. if necessary. Check building drains for blockage
Machine
does not
turn
VFD Check VFD by removing inspection panel and record any
numbers or letters displayed. If no display turn power o to
machine at breaker for 2 minutes and turn poiwer back on
to reset. If still no display replace VFD
Machine
tumbles in
one direc-
tion
VFD Remove inspection cover at rear and record in only numbers
or letters displayed. See fault code section for more info.
VFD Inspect yellow enable wires from main relay PCB and at VFD
Excessive
vibration
Mounting System Check these areas: • Strength of mounting structure, con-
crete or base. • Mounting bolts may be loose and need
tightening.
Drive Belt Worn drive belt can cause vibration and noise.
Loading Note: Small loads contribute to out of balance loading and
increase vibration.
Machine
does not
spin
Pressure Switch Check pressure switch for continuity across terminals #21 &
#22 indicating pressure switch has reset to the empty posi-
tion. If no continuity, change pressure switch.
Machine
starts and
does not
operate
VFD Check yellow enable wires from relay PCB P13 & motor
P14to VFD advances through cycle are connected. Check
fault code on VFD before removing power from the drive.
Check orange P-15 wire for signal from door switches.
Machine
does not
stop
Main PCB Main PCB controls time cycle at end of cycle
Braking Resistors Check braking resistors for continuity. Verify ohms resis-
tance by Molex.
Water leak-
age around
loading door
Door Adjustment Door may need adjustment due to abuse or wear. Check
tightness around perimeter using a dollar bill. Adjust left
to right tightness by shims at door lock or hinge side. It is
important to center gasket to tub opening before tighten-
ing door to hinge bolts. Chalk may be used on tub front
to show point of contact with tub. If gasket is deformed,
worn, or damaged, replace. Refer to parts section for door
gasket expander kit.
