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 "WIRING DIAGRAM" on page 33 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.

Cause
Reset and Recovery
Motor Stall
Motor Run-On
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.
Optical Sensor
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.
Flow meter error
Continuous Flow
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.
Over current
Motor over current
detected
Motor drew too much current
Attempt to perform a manual regeneration. If error continues, call technical
support.
Flow meter error
No flow detected
No flow has been detected for 7
days.
Error will clear when a flow pulse is detected. Check to ensure meter cable is
properly installed and meter spins freely. Clear meter of debris if necessary. If error
continues, call technical support.
No regeneration for
100 days
The valve has not regenerated in
more than 100 days.
Inititate a regeneration.
Service Interval
Service Interval timer has expired. From within Master Settings, navigate to the Assistance/Mainten. Interval screen
and set a new Service Interval time.
Memory Corruption
Error
Internal memory inconsistent or
corrupted
1. Cycle power to XTR2 controller
2. Drain supercap and cycle power to XTR2 controller.
3. If error continues, call technical support.
No Salt Detect
(international
version only)
When chlorine generator is on
but does not read salt from the
chlorine generator.
Error will clear if salt is added to the brine tank and a manual regeneration is
performed.
Emergency Regen
Occured
Over 105% of the total capacity
(e.g., volume plus reserve) has
been depleted
Error will clear when regeneration occurs. When the Emergency Regen is
enabled, the Emegency Regen Occured error alert will display to let the user know
an Emergency Regen occured. Repeated Emergency Regens may indicate an
undersized system.
