Possible Causes

Failed real‑time clock circuit on control board, Power interruptions without backup, Defective internal capacitor or backup battery (if equipped)

How to Fix / Troubleshooting

Safety first: Unplug the softener before removing the control board.

  • Step 1 – Confirm power stability: Ensure the softener is plugged into a non‑switched, grounded outlet. Avoid plugging into circuits that are frequently turned off.
  • Step 2 – Reprogram time: Set the current time and regeneration time. Monitor for 24 hours to see if the clock drifts or resets.
  • Step 3 – Inspect control board: Remove the control cover and inspect the board for leaking capacitors or corrosion near the clock circuit.
  • Step 4 – Replace control board: If the timekeeping continues to fail and Err 9 reappears, replace the GE electronic control board. Transfer the overlay and reconnect all harnesses.
  • Note: There are no user‑serviceable parts on the board; component‑level repair is not recommended for homeowners.
