Troubleshooting
The technology upon which the Autotrol Performa
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 ! after 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.
Valve Troubleshooting
Problem Possible Cause Solution
1. Control will not draw brine. a. Low water pressure.
b. Restricted drain line.
c. Injector plugged !
d. Injector defective !
e. Valve (2 and/or 4) not closed.
a. Set pump to maintain 30 psi at conditioner.
b. Remove restriction.
c. Clean injector and screen.
d. Replace injector.
e. Remove foreign matter from disc and check
disc for closing by pushing in on stem. Replace
if needed.
2. Brine tank overflow. a. Brine valve (1) being held open.
b. Uncontrolled brine refill flow rate !
c. Valve (3 or 4) not closed during brine draw
causing refill.
d. Air leak in brine line.
a. Manually operate valve stem to flush away
obstruction.
b. Remove variable salt controller to clean.
c. Flush out foreign matter by holding disc open
and manually operating valve stem.
d. Check all connections in brine line for leaks.
Refer to instructions.
3. System using more or less salt
than salt control is set for.
a. Inaccurate setting.
b. Foreign matter in controller causing
incorrect flow rates
!
c. Defective controller.
a. Correct setting.
b. 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).
c. Replace controller.
4. Intermittent or irregular brine
draw.
a. Low water pressure.
b. Defective injector !
a. Set pump to maintain 30 psi at conditioner.
b. Replace both injector and injector cap.
5. No conditioned water after
regeneration.
a. Unit did not regenerate.
b. No salt in brine tank.
c. Plugged injector !
a. Check for power.
b. Add salt.
c. Clean injector. Flush with water.
6. Control backwashes at
excessively low or high rate.
a. Incorrect backwash controller used.
b. Foreign matter affecting controller
operation
!
a. Replace with correct size controller.
b. Remove controller and ball. Flush with water.
7. Flowing or dripping water at
drain or brine line after
regeneration.
a. Drain valve (5 or 6) or brine valve (1) held
open by foreign matter or particle.
b. Valve stem return spring on top plate
weak.
a. Manually operate valve stem to flush away
obstruction.
b. Replace spring.
8. Hard water leakage during
service.
a. Improper regeneration.
b. Leaking of bypass valve !
c. O-ring around riser tube
damaged
!
a. Repeat regeneration making certain that the
correct salt dosage is set.
b. Replace O-ring.
c. Replace O-ring.
