TROUBLESHOOTING
Problem
Cause
Correction
Valve constantly
regenerates
Error in programming has caused
a regeneration loop condition in the
control.
Disconnect the motor from the control circuit board (see "WIRING DIAGRAM" on
page 30 for location on circuit board). A Motor Stall error will occur, allowing
access to Master Settings. Navigate to the Valve screen and check Regen Type
settings. Ensure that the value for Capacity is larger than the value for Hardness,
and save settings.
If the error continues to occur, unplug the unit, put it into bypass and contact
technical support.
Error Alerts
NOTE: An Error Alert appears on the Home screen if an error
condition is detected. Press the Error Alert button
to view the error message.
NOTE: Most error alerts are cleared at regeneration. If the
error persists following a regeneration attempt the
appropriate reset and recovery procedure below or
contact technical support.

Reset and Recovery
Motor Stall
No changes
detected in the
optical sensor for 6
seconds
No state changes in the optical
sensor are detected for six
seconds.
Unplug the unit and plug back in. Allow the control to attempt to find position again.
Verify the optical sensor is in place with the wires connected to the circuit board.
Verify the motor and drive train components are in good condition and assembled
properly. Check the valve and verify that the piston travels freely. Replace/
reassemble the various components as necessary.
Plug the unit back in and observe its behavior. If the error reoccurs, unplug the unit,
put it into bypass and contact technical support.
Motor Run-On
Undesired change
detected in the
optical sensor
An undesired optical sensor state
change occurred.
Non-critical error. Extra optical sensor pulse detected. Press the Regeneration
button to advance motor to clear error.
Plumbing Leak
The flow meter has reported
continuous flow for more than 24
hours.
Error will clear when flow to meter drops below 0.5 GPM or 1 LPM. If continuous
flow is expected, turn plumbing leak detection off in Master Settings.
Valve Position
Valve took over a
minute to find cycle
step
Valve has failed to find position in
one minute.
Unplug the unit and plug it back in. If error continues, call technical support. Check
the valve and verify that the piston travels freely. Replace/reassemble the various
components as necessary.
Reset Error
Probable
Mechanical Failure
The valve has reset at least five
times in a short amount of time.
Attempt to perform a manual regeneration. If error continues, call technical
support.
