Troubleshooting Guide
Problem
Cause
Solution
1. Unit fails to regenerate.
a. Faulty electrical circuit.
b. Defective clock motor.
c. Low inlet pressure.
d. Drain line restricted.
e. All skipper tabs in the "out" position.
f. The brine injector is plugged.
g. Main diaphragm is torn.
h. Timer knob out of alignment with
Time Gear.
i.
Defective solenoid coil.
a. Verify electrical service (fuse, circuit
breaker, light switch, pull chain, power
cord).
b. Replace the clock motor.
c. Verify that the service inlet pressure is
a minimum of 20 psi.
d. Insure the drain line is free of kinks.

g. Replace diaphragm.
h. Realign the Knob and Gear.
i.
Test and replace the solenoid coil.
2. Hard water to service.
a. The bypass valve is open or faulty.
b. No salt in storage tank.
c. Not enough water in the storage tank.
d. Unit fails to draw brine.
e. Excessive water usage.
f. Unit not regenerating.
g. Loss of resin.
h. Change in raw water hardness.
i.
Leak at the distributor tube.
a. Close bypass valve.
b. Add salt.
c. Verify that the safety float is properly
set.
d. See symptom/cause # 6.
e. Check regeneration frequency.
f. See symptom/cause # 1.
g. See symptom/cause # 4.
h. Test water hardness.
i.
Verify that the distributor tube is seated
correctly and is not cracked.
3. Excessive salt usage.
a. Excessive water in storage tank.
b. Regeneration is taking place too
frequently.
c. Faulty safety float.

6. Control fails to draw
brine.
a. Brine injector plugged.
b. Filter screen plugged
c. Loose brine line connection.
d. Drain line is restricted
e. Low inlet pressure.
f. Main diaphragm is torn.
g. Solenoid plunger stuck open.
a. Clean and replace injector.
b. Clean and replace screen.
c. Verify that all the brine line connections
are tight.
d. Insure that the drain line is not kinked
or plugged.
e. Verify that the service inlet pressure is
a minimum of 20 psi.
f. Replace diaphragm.
g. Clean or replace the solenoid plunger
assembly.
7. Continuous flow to
drain.
a. Drain plunger stuck open.
b. Clock motor stalled.
a. Clean or replace the drain plunger
assembly.
b. Replace the clock motor.
8. Loss of water pressure.
a. Iron build up in mineral tank.
b. Lower distributor basket crushed.
c. Resin has lost mechanical strength.
a. Increase salt dosage or regenerate
more frequently.
