Issue
A. Unit fails to initiate a
regeneration cycle.
B. FILTER BLEEDS TASTE
AND ODOR OR SEDIMENT
C. Low water pressure.
D. Filter media in drain line.
E. Valve continuously cycles. 1. Defective position sensor PCB.
F. Flow to drain continuously.
Trouble Shooting
Possible Cause
1. No power supply.
2. Defective circuit board.
3. Power failure.
1. By‐pass valve open.
2. Electrical service to unit has been
interrupted
3. Defective or stripped media bed
4. Quality of water has worsened
5. Filter capacity too small
6. Filter not backwashing enough
7. Leak between valve and central tube.
8. Internal valve leak.
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.
1. Air in water system.
2. Incorrect drain line flow control (DLFC)
button.
1. Valve settings incorrect.
2. Foreign material in control valve.
3. Internal leak.
Possible Solution
Check electrical service, fuse, etc.
Replace faulty parts.
Reset time of day.
Close by‐pass valve.
Assure permanent electrical service (check
fuse, plug or switch)
Replace media
Have water sample analyzed to determine
any change
Replace with larger unit or add another
filter
Be sure control is not clogged or drain
line restricted. Be sure water pressure
has not dropped and that pump has
sufficient capacity.
Check if central tube is cracked or o‐ring is
damaged. Replace faulty parts.
Replace valve seals, spacer, and piston
assembly.
Clean pipes.
Clean control and add resin cleaner to clean
bed. Increase regeneration frequency.
Remove piston and clean control valve.
Check well system for proper air eliminator
control.
Check for proper flow rate.
Replace faulty parts.
Check valve settings.
Clean control.
Replace seals, spacers, and piston assembly.
