• Control Valve Fault
Problem
Cause
Correction
1. Softener fails
to regenerate.
A. Electrical service to unit has been
interrupted.
B. Regeneration cycles set incorrect.
C. Controller is defective.
D. Motor fails to work.
A. Assure permanent electrical service (Check fuse, plug, pull
chain or switch).

C. Replace controller.
D. Replace motor.
2. Regeneration
t i m e i s n o t
correct.
A. Time of Day not set correctly.
B. Power failure more than 3 days.
Check program and reset time of day.
3. S o f t e n e r
supplies hard
water.
A. Bypass valve is open or leaking.
B. No salt in brine tank.
C. Injector plugged.
D. Insuffi cient water fl owing into brine
tank.
E. Leak at O-ring on riser pipe.
F. Internal valve leak.
G. Regeneration cycles not correct.
H. Shortage of resin.
I. Bad quality of feed water or turbine
blocked.
A. Close or repair bypass valve.
B. Add salt to brine tank and maintain salt level above water level.
C. Change or clean injector.
D. Check brine tank refi ll time.
E. Make sure riser pipe is not cracked. Check O-ring and tube pilot.
F. Change valve body.
G. Set correct regeneration cycles in the program.
H. Add resin to mineral tank and check whether resin leaks.
I. Reduce the inlet turbidity, clean or replace turbine.
4. Softener fails
to draw brine.
A. Line pressure is too low.
B. Brine line is plugged.
C. Brine line is leaking.
D. Injector is plugged.
E. Internal valve leak.
F. Drain line is plugged.
G. Brine valve is faulted.
A. Increase line pressure.
B. Clean brine line.
C. Replace brine line.
D. Clean or replace injector.
E. Replace valve body.
F. Clean drain line fl ow control.
G. Check the motor of brine valve.
5. Unit used too
much salt.
A. Improper salt setting.
B. Excessive water in brine tank.
A. Check salt usage and salt setting.
B. See problem No.6.
6. E x c e s s i v e
water in brine
tank.
A. Refi ll time too long.
B. Too much water after brine.
C. Foreign material in brine valve and
plugged drain line fl ow control.
D. No safety brine valve installed but
power failure while brining.
E. Safety brine valve breakdown.
A. Reset correct refi lling time.
B. Check the injector and make sure no stuff in the brine pipe.

salt tank.
E. Repair or replace safety brine valve.
7. Pressure lost
or rust in pipe
line
A. Iron in the water supply pipe.

C. Fouled resin bed.
D. Too much iron in the raw water.
A. Clean the water supply pipe.
B. Clean valve and add resin cleaning chemical, increase frequency
of regeneration.
C. Check backwash, brine draw and brine tank refi ll. Increase
frequency of regeneration and backwash time.
D. Iron removal equipment is required to install before softening.
8. Loss of resin
through drain
line.
A. Air in water system.
B. Bottom strainer broken.
C. Improperly sized drain line control.
A. Assure that well system has proper air eliminator control.
B. Replace strainer.
