Check to ensure that water is turned on and opera ng.
Check black or white wires at Molex plug on PCB at main
controller and at relay PCB.
Check pressure switch con nuity between terminals. If no
con nuity, check pressure switch hose for obstruc on. If hose
okay, change pressure switch.
Check coil con nuity at terminals and replace if no con nuity.
Check water inlet screens for blockage and clean if necessary.
Check to ensure that water is turned on and opera ng.
Check black or white wires at Molex plug on PCB at main
controller and at relay PCB.
Check pressure switch con nuity between terminal contacts. If
no con nuity, check pressure switch hose for obstruc on. If hose
okay, change pressure switch.
Check these areas:
• Drain valve blockage
• Drain valve motor 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.
Check black and white wires at molex plug on main PCB
controller and at main relay PCB
Check coil con nuity at terminals and replace if no con nuity.
Check water inlet screens for blockage and clean if necessary.
Check to ensure that water is turned on and opera ng.
Check pressure switch con nuity between terminals. If no
con nuity, check pressure switch hose for obstruc on. If hose
okay, 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 if inadequate
size. If necessary check building drains for blockage.
Check VFD by removing inspec on panel and record any
numbers or le ers displayed. If no display turn power off to
machine at breaker for 2 minutes and turn power back on to
reset. If s ll no display, replace VFD.
Remove inspec on cover at rear and record in only numbers or
le ers displayed. See fault code sec on for more info.
Inspect yellow enable wires from main relay PCB and at VFD.
Check these areas: • Strength of moun ng structure, concrete or
base. • Moun ng bolts may be loose and need ghtening.
