Water Valve Coil Check coil continuity at terminals and replace if no
continuity. 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 wire harness.
Hot water
does not
enter tub in
wash
Water Valve Coil Check coil continuity at terminals and replace if no
continuity. Check for 120 V power from main relay PCB.
Water Inlet Check water inlet screens for blockage and clean if
necessary.
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

wash
Water Valve Coil Check coil continuity at terminals and replace if no
continuity.
Water Inlet
Screens

continuity.
Water Inlet
Screens
Check water inlet screens for blockage and clean if
necessary.
Water Check to ensure that water is turned on and operating.

softener
compartment
Pressure Switch Check pressure switch continuity between terminals. If
no continuity, check pressure switch hose for obstruction.

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. Check if
inadequate size. If necessary check building drains for
blockage.
