Control Valve Trouble Shooting
Problem Possible Cause Solution
Control Valve fails to draw
brine
Injector is plugged Remove Injector and clean or replace
Faulty Brine Piston Replace Brine Piston
Brine line tubing connection leak Inspect Tubing and Fittings for air leak
Drain line restriction or debris can cause
excess back pressure on Injector
Inspect drain line and clean to correct
restriction
Drain line too long or elevated too high Shorten length and or height
Low water pressure
Check incoming water pressure. Water
pressure must remain at minimum of 40
psi
Water running to drain
Power outage during regeneration
Upon power being restored Control Valve
will finish the remaining regeneration time.
Reset time of day.
Damaged Seal and Spacer Stack
Assembly
Replace Seal and Spacer Stack Assembly
Piston assembly failure Replace Piston Assembly
Drive Cap Assembly not tightened in
properly
Re-tighten the Drive Cap Assembly
Err - 1001 = Control unable to
sense motor movement
Motor not inserted full to engage pinion,
motor wires broken or disconnected
Disconnect power, make sure motor is
fully engaged, check for broken wires,
make sure two pin connector on motor is
connected to the two pin connection on the
Circuit Board labeled MOTOR. Press
NEXT and REGEN buttons at the same
time for 3 seconds to resynchronize
software with piston.
Circuit Board not properly snapped into
drive bracket
Properly snap Circuit Board into drive
bracket and then Press NEXT and REGEN
buttons at the same time for 3 seconds to
resynchronize software with piston.
Missing reduction gears Replace missing gears
Err - 1002 = Control valve
motor ran too short and was
unable to find the next cycle
position and stalled
Foreign material is lodged in control valve
Open up Control Valve and pull out piston
assembly and Seal and Spacer Stack
Assembly for inspection. Press NEXT and
REGEN buttons at the same time for 3
seconds to resynchronize software with
piston.
Mechanical binding
Check Piston and Seal and Spacer Stack
Assembly, check Reduction Gears, check
Drive Bracket and Main Drive Gear
Interface. Press NEXT and REGEN
buttons at the same time for 3 seconds to
resynchronize software with piston.
Main Drive Gear too tight
Loosen Main Drive Gear. Press NEXT and
REGEN buttons at the same time for 3
seconds to resynchronize software with
piston.
Improper voltage being delivered to Circuit
Board
Verify that proper voltage is being
supplied. Press NEXT and REGEN
