Suggested Remedy
Check coil continuity at terminals and replace if no continuity.
Check for 120 V power from main relay PCB
Check water inlet screens for blockage and clean if necessary
screens
Check to insure that water is turned on and operating.
Check black or white wires at Molex plug on PCB at main control-
ler and at relay PCB.
Check pressure switch continuity between terminals . If no con-
tinuity, check pressure switch hose for obstruction. If hose okay,
change pressure switch.
Check coil continuity at terminals and replace if no continuity.
Check water inlet screens for blockage and clean if necessary.
Check to insure that water is turned on and operating.
Check black or white wires at Molex plug on PCB at main control-

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.
