2. Defective circuit board.
Replace faulty parts.
3. Power failure.
Reset time of day.
1. By-pass valve open.
Close by-pass valve.
2. Electrical service to unit has been
interrupted
Assure permanent electrical service (check
fuse, plug or switch)
3. Defective or stripped media bed
Replace media
4. Quality of water has worsened
Have water sample analyzed to determine
any change
5. Filter capacity too small
Replace with larger unit or add another
filter
6. Filter not backwashing enough
Be sure control is not clogged or drain
line restricted. Be sure water pressure
has not dropped and that pump has
sufficient capacity.
7. Leak between valve and central tube.
Check if central tube is cracked or o-ring is
damaged. Replace faulty parts.
8. Internal valve leak.
Replace valve seals, spacer, and piston
assembly.
1. Iron or scale build up in line feeding unit.

Check well system for proper air eliminator
control.
2. Incorrect drain line flow control (DLFC)
button.
Check for proper flow rate.
E. 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.
