Trouble Shooting
Issue Possible Cause Possible Solution
1. No power supply. Check electrical service, fuse, etc.
2. Defective circuit board. Replace faulty parts.
3. Power failure. Reset time of day.
4. Defective meter. Replace turbine meter.
1. By-pass valve open. Close by-pass valve.
2. Out of salt or salt level below water level. Add salt to tank.
3. Plugged injector / screen. Clean parts.
4. Flow of water blocked to brine tank. Check brine tank refill rate.
5. Hard water in hot water tank. Repeat flushing of hot water tank required.
6. Leak between valve and central tube. Check if central tube is cracked or o-ring is
damaged. Replace faulty parts.
7. Internal valve leak. Replace valve seals, spacer, and piston
assembly.
8. Reserve capacity setting too low. Increase reserve capacity.
9. Not enough capacity. Increase salt dosage.
1. Refill time is too high. Check refill time setting.
2. Defective flow control. Replace.
1. Iron or scale build up in line feeding unit. Clean pipes.
2. Iron build up inside valve or tank. Clean control and add resin cleaner to clean
bed. Increase regeneration frequency.
3. Inlet of control plugged due to foreign
material. Remove piston and clean control valve.
4. Deteriorated resin. (Maybe caused from
high chlorine or chloramines.) Re-bed unit. Consider adding carbon pre-
treatment.
1. Air in water system. Check well system for proper air eliminator
control.
2. Incorrect drain line flow control (DLFC)
button. Check for proper flow rate.
1. Plugged injector or screen. Clean parts.
2. Valve not regenerating. Replace circuit board, motor, or control.
3. Foreign material in brine valve. Clean parts.
4. Unit not drawing brine. Check for vacuum leak in brine line
connections.
1. Drain line flow control is plugged. Clean parts.
2. Injector or screen is plugged. Clean parts.
3. Inlet pressure too low. Increase pressure to 25 PSI.
4. Internal valve leak. Replace seals, spacers, and piston assembly.
5. Safety valve closed. Check for leak in brine line connections.
Replace safety float assembly.
6. Vacuum leak in brine line. Check for leak in brine line connections.
Tighten all connections.
7. Drain line has kink in it or is blocked. Check drain line.
H. Valve continuously
cycles. 1. Defective position sensor PCB. Replace faulty parts.
1. Valve settings incorrect. Check valve settings.
2. Foreign material in control valve. Clean control.
3. Internal leak. Replace seals, spacers, and piston assembly.
4. Piston is stuck in position. Motor may have
failed or gears have jammed or disengaged. Check for power to motor. Check for loose
wire. Check for jammed gears or gears
disengaged. Replace faulty parts.
J. Valve makes beeping
sound. 1. The piston has not advanced to the next
cycle position properly. Check for power to motor. Check for loose
wire. Check for jammed gears or gears
disengaged.
I. Flow to drain
continuously.
G. Unit fails to draw brine.
A. Unit fails to initiate a
regeneration cycle.
B. Water is hard.
E. Resin in drain line.
C. Salt use is high.
D. Low water pressure.
F. Too much water in brine
tank.
