Display shows “Service” or “Call for Service” and softener may not operate normally.

Safety first: Disconnect power before opening the control head.

• Step 1 – Check for additional codes: Many GE models allow viewing detailed error codes in a diagnostic menu. Enter diagnostics per the manual and note any specific codes (Err 1–Err 10, etc.).
• Step 2 – Power cycle: Unplug the unit for 5 minutes, then restore power. If “Service” clears and does not return, monitor operation.
• Step 3 – Inspect obvious issues: Verify the drive motor, turbine, and brine system are functioning (no unusual noises, no leaks, brine level changes during regen).
• Step 4 – Address underlying codes: Use the specific error entries in this guide to correct the root cause. Clearing the fault usually removes the “Service” message.
• Step 5 – Replace control board if persistent: If no specific code is present and the message returns after reset, the electronic control board may be failing and should be replaced.

Note: If you cannot access diagnostics or are unsure of the codes, contacting GE support with the model and serial number is recommended.
