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 regenerant.
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. Regenerant tank overflow.
A. Regenerant valve (1) being held open.
B. Uncontrolled regenerant refill flow rate
!
C. Valve (3 or 4) not closed during regenerant
draw causing refill.
D. Air leak in regenerant 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 regenerant 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
regenerant draw to clean controller (after so
doing, position control to “purge” to remove
regenerant from tank).
C. Replace controller.
4. Intermittent or irregular
regenerant 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 regenerant 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 regenerant line after
regeneration.
A. Drain valve (5 or 6) or regenerant 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.
