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.
1. By-pass valve open.
Close by-pass valve.
2. Out of salt.
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.
C. Salt use is high.
1. Refill time is too high.
Check refill time setting.
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.
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.
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.
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.
