Possible Causes
Defective auxiliary valve on water softener, Broken valve coil, Wiring fault to auxiliary valve, Control board output failure
How to Fix / Troubleshooting
Safety first: Disconnect power and close the water tap before accessing side components.
- 1. Access auxiliary valve: Remove the side panel to locate the auxiliary / regeneration valve on the water softener block.
- 2. Test coil: Disconnect the valve connector and measure coil resistance. An open circuit indicates a failed valve that must be replaced.
- 3. Inspect wiring: Check the harness from the valve to the control board for damage or loose connections.
- 4. Replace valve or softener: If the valve is integrated and not serviceable separately, replace the complete water softener assembly.
