Issue
A.
Unit fails to initiate a regeneration
cycle.
B.
Water is hard.
C.
Salt use is high.
D.
Low water pressure.
E.
Resin in drain line.
F.
Too much water in brine tank.
G.
Unit fails to draw brine.
32
H.
Valve continuously cycles.
I.
Flow to drain continuously.
J.
Valve makes beeping sound.
Possible Cause
1. No power supply.
2. Defective circuit board.
3. Power failure.
4. Defective meter.
1. By-pass valve open.
2. Out of salt or salt level below water level.
3. Plugged injector / screen.
4. Flow of water blocked to brine tank.
5. Hard water in hot water tank.
6. Leak between valve and central tube.
7. Internal valve leak.
8. Reserve capacity setting too low.
9. Not enough capacity.
1. Refill time is too high.
2. Defective flow control.
1. Iron or scale build up in line feeding unit.
2. Iron build up inside valve or tank.
3. Inlet of control plugged due to foreign
material.
4. Deteriorated resin. (Maybe caused from high
chlorine or chloramines.)
1. Air in water system.
2. Incorrect drain line flow control (DLFC) button.
1. Plugged injector or screen.
2. Valve not regenerating.
3. Foreign material in brine valve.
4. Unit not drawing brine.
1. Drain line flow control is plugged.
2. Injector or screen is plugged.
3. Inlet pressure too low.
4. Internal valve leak.
5. Safety valve closed.
6. Vacuum leak in brine line.
7. Drain line has kink in it or is blocked.
1. Defective position sensor PCB.
1. Valve settings incorrect.
2. Foreign material in control valve.
3. Internal leak.
4. Piston is stuck in position. Motor may have failed or
gears have jammed or disengaged.
1. The piston has not advanced to the next cycle
position properly.
Possible Solution
Check electrical service, fuse, etc.
Replace faulty parts.
Reset time of day.
Replace turbine meter.
Close by-pass valve.
Add salt to tank.
Clean parts.
Check brine tank refill rate.
Repeat flushing of hot water tank required.
Check if central tube is cracked or o-ring is damaged.
Replace faulty parts.
Replace valve seals, spacer, and piston assembly.
