Display shows E09 and the softener reports low inlet pressure or fails to regenerate properly.

Safety: Turn off power to the softener. Use caution when opening plumbing connections; relieve pressure first.

Steps to troubleshoot E09 (Low Inlet Pressure):

• 1. Measure water pressure: Attach a pressure gauge to a nearby hose bib or faucet. Confirm that static pressure meets SpringWell's minimum requirement (typically 20–25 psi or higher).
• 2. Check valves: Ensure the SpringWell bypass is fully in service position and that the main shutoff valve is fully open.
• 3. Clean inlet screen: Shut off water and relieve pressure. Remove the inlet fitting or screen from the SpringWell control valve and rinse away sediment or debris. Reinstall securely.
• 4. Inspect well system (if applicable): If you are on a well, verify that the pressure switch, pump, and pressure tank are functioning correctly. Low system pressure must be corrected before the softener can operate reliably.
• 5. Reset error: Restore water and power, then clear the error via the control panel. If E09 returns despite adequate pressure and a clean inlet, the pressure sensing circuit in the SpringWell control head may be faulty and require replacement.
