Display shows E13 and the unit reports a valve position error.

Safety: Bypass the softener and unplug it before working on the valve head.

Steps to troubleshoot E13 (Valve Position Error):

• 1. Observe valve movement: Remove the control cover and initiate a manual regeneration. Watch the cam/rotor and note if it stops mid-cycle or hunts for position.
• 2. Check encoder connection: Locate the position sensor or encoder on the drive assembly. Ensure its wiring harness is firmly connected to the control board.
• 3. Inspect for mechanical damage: Look for cracked cams, stripped gears, or loose set screws that could cause misalignment between the motor and valve.
• 4. Realign or replace encoder: If the encoder is misaligned, adjust it per SpringWell instructions. If damaged, replace the SpringWell valve position encoder or drive assembly.
• 5. Replace control head if needed: If mechanical parts and encoder are good but E13 persists, the control board may not be reading the signal correctly and the SpringWell control head should be replaced.
