Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the softener before touching any internal electronics. Do not attempt board-level solder repairs unless you are qualified.
Steps to diagnose:
- 1. Power reset: Unplug the transformer for 5–10 minutes, then plug back in. If the valve immediately moves or the error reappears, suspect a stuck relay or driver.
- 2. Inspect for corrosion: Remove the control board and inspect both sides for white or green corrosion, burnt spots, or insect damage. If present, the board should be replaced.
- 3. Check motor/coil wiring: Verify that the drive motor and any valve coils are wired to the correct terminals and that no wires are shorted together.
- 4. Replace control board: If the error persists and wiring is correct, replace the EcoWater main control board. Transfer any jumpers or programming as specified in the service manual.
Because this fault involves electronic switching components, most homeowners will need an EcoWater dealer or technician to complete diagnosis and replacement.
