compartment.
Water Valve Coil Check coil continuity at terminals and replace if no 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.
Pressure Switch
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.
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.
