Error Codes
Control Valve Error Code Diagnosis
Under normal operating conditions, when your control valve is in the “in service” position, the
display should alternate between the current time of day and the number of days remaining
(for filters and time clock softeners) or gallons remaining (for metered softeners) until the next
regeneration.
This is the “home display.” If the valve is currently going through a regeneration cycle, the
display will show the cycle step on the left side of the display and the number of minutes
remaining in that step on the right side of the display.
If any other information is being displayed, then the valve is informing you of an issue. There
are five error codes which could indicate an issue with the control valve. When an error is
being displayed, the valve will be in a stopped position, and the buttons will not respond to
being pressed.
Even if the cause of the error code is corrected, the error code will not clear until the power
supply has been disconnected and reconnected (this will be referred to as “cycling” the power).
All error codes are displayed as the letters “Err” followed by a flashing number 2-6:
There are five (5) error codes that could indicate a possible problem with the control valve:
Error 2 -
Valve is searching for homing slot. Allow valve to continue running. If the homing slot
is found, the valve will return to the home display, otherwise, another error code will appear.
Error 3
- No encoder slots are being seen. This occurs when the motor is running, but the
encoder is not seeing any of the slots in the encoder wheel. This can happen if the encoder has
been disconnected, but most commonly occurs when debris in the valve body has stopped the
piston, causing the encoder wheel to be unable to turn.
1. Check encoder connection. If the encoder is plugged in and snapped into place, skip to step #2 below.
If encoder is disconnected, reconnect it and cycle power to clear the error.
2. Disconnect powerhead from valve body, cycle power to clear the error code. Manually cycle the
powerhead through the regeneration cycle steps to verify that the motor can cycle properly while the
powerhead is disconnected from the valve body. If the error 3 does not reappear, skip to step #3 below.
If the error 3 does reappear, order a board & motor kit to replace the circuit board & motor.
3. Remove piston and seals from the valve body and inspect valve body for debris. Replace the seal &
spacer kit. Inspect piston and replace piston if Teflon coating is worn.
