Softener is stuck in regeneration and does not return to service mode (no code shown)

Safety first: Immediately place the unit in bypass to restore water service and prevent water waste. Unplug the softener.

• Check cam position: Remove the valve cover and note the position of the cam/rotor. If it is between positions, the cycle has stalled.
• Manual return to service: If your Watersoft model allows, manually rotate the cam to the service position to restore normal flow.
• Inspect mechanical parts: Look for broken gears, loose linkages, or debris in the valve. Replace damaged components and consider a full piston/seal kit if movement is stiff.
• Test position switch: Use a multimeter to verify the position switch changes state as the cam moves. Replace if faulty.

After repair, run a supervised manual regeneration to ensure the cycle completes and the unit returns to service.
