Suggested Remedy
Check VFD by removing inspection panel and record any
numbers or letters displayed. 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
Remove inspection cover at rear and record in only numbers
or letters displayed. See fault code section for more info.
Inspect yellow enable wires from main relay PCB and at
VFD
Check these areas: • Strength of mounting structure, con-
crete or base. • Mounting bolts may be loose and need
tightening.
Worn drive belt can cause vibration and noise.
Note: 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 posi-
tion. If no continuity, change pressure switch.
Check yellow enable wires from relay PCB P13 & motor P14
to 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.
Main PCB controls time cycle at end of cycle
Check braking resistors for continuity. Verify ohms resis-
tance by Molex.
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.
