Troubleshooting
The technology upon which the control valve is based is
well established and proven in service over many years.
However, should a problem or question arise regarding
the operation of the system, the control can very easily be
serviced. For parts mentioned, refer to exploded views in
the Replacement Parts section of this manual.
IMPORTANT: Service procedures that require the water
pressure to be removed from the system are marked with
a “
§” a er the possible cause. To remove water pressure
from the system, put the bypass valve or three-valve
bypass into the bypass position and open the backwash
drain valve (the seventh valve back from the control) with
a screwdriver. Restore system water pressure when the
service work is completed.
The problems outlined below are the most common
occurances of problems. If you are unable to solve your
problem with this manual, contact the manufacturer.
Valve Troubleshooting
Problem Possible Cause Solution
Control will not draw brine. Low water pressure. Set pump to maintain 30 psi at conditioner.
Restricted drain line. Remove restriction.
Injector plugged§ Lean injector and screen.
Injector defective§ Replace injector.
Valve (2 and/or 4) not closed. Remove foreign matter from disc and check
disc for closing by pushing in on stem. Replace
if needed.
Brine tank overflow. Brine valve (1) being held open. Manually operate valve stem to flush away
obstruction.
Uncontrolled brine refill flow rate§ Remove variable salt controller to clean.
Valve (3 or 4) not closed during brine draw
causing refill.
Flush out foreign matter by holding disc open
and manually operating valve stem.
Air leak in brine line. Check all connections in brine line for leaks.
Refer to instructions.
System using more or less salt than salt control
is set for.
Inaccurate setting. Correct setting.
Foreign matter in controller causing incorrect
flow rates§
Remove variable salt controller and flush out
foreign matter. Manually position control to
brine draw to clean controller (after so doing,
position control to “purge” to remove brine
from tank).
Defective controller. Replace controller.
Intermittent or irregular brine draw. Low water pressure. Set pump to maintain 30 psi at conditioner.
Defective injector§ Replace both injector and injector cap.
No conditioned water after regeneration. Unit did not regenerate. Check for power.
No salt in brine tank. Add salt.
Plugged injector§ Clean injector. Flush with water.
Control backwashes at excessively low or high
rate.
Incorrect backwash controller used. Replace with correct size controller.
Foreign matter affecting controller operation§ Remove controller and ball. Flush with water.
Flowing or dripping water at drain or brine line
after regeneration.
Drain valve (5 or 6) or brine valve (1) held open
by foreign matter or particle.
Manually operate valve stem to flush away
obstruction.
Valve stem return spring on top plate weak. Replace spring.
Hard water leakage during service. Improper regeneration. Repeat regeneration making certain that the
correct salt dosage is set.
Leaking of bypass valve§ Replace O-ring.
O-ring around riser tube
damaged§
Replace O-ring.
