Check coil continuity at terminals and replace if no continuity.
Check water inlet screens for blockage and clean if necessary.
Check to ensure that water is turned on and operating.
Check pressure switch continuity between terminal contacts. If no
continuity, check pressure switch hose for obstruction. If the hose is
okay then change pressure switch.
Check for blockage in pressure switch hose. Check for pressure
switch opening circuit across terminals. Replace switch if contacts
do not open.
Check hoses and drain valve for blockage. Check to make sure
building drain is of adequate size. Check building drains for
blockage.
Check VFD by removing top panel. If no display turn power off to
machine at breaker for 2 minutes and turn power back on to reset.
If still no display replace VFD.
See DISPLAYED WASHER FAULTS section for more info.
Inspect yellow enable wires from main relay PCB and at VFD
Check these areas:
• Strength of mounting structure, concrete or base.
• Mounting bolts may be loose and need tightening.
Worn drive belt can cause vibration and noise.
Small loads contribute to out of balance loading and increase
vibration.
Check pressure switch for continuity across terminals #21 & #22
indicating pressure switch has reset to the empty position. If no
continuity, change pressure switch.
Check yellow enable wires from PCB relay board connection P13 &
P14 to the VFD. Check connection of orange wire at P15 from door
switches.
Main PCB controls time of the cycle and the end of cycle.
Check braking resistors for continuity. Verify ohms resistance at
braking resistors with wires removed.
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 tightening 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.
Machine accepts coins, When machines starts the buzzer will sound
and then the machine stops. The display will then show "OPEN
DOOR". Replace stop button.
