How to Fix / Troubleshooting
Safety: Unplug the unit and place it in bypass. Prepare for possible brine spillage.
- 1. Lower brine level: Manually remove excess brine using a bucket or siphon until the float is below the alarm level.
- 2. Free the float: Remove the brine well cover and ensure the float rod moves freely. Clean off salt buildup and verify the air check is not jammed.
- 3. Check brine drain: Inspect the brine drain hose for obstructions or improper routing. Correct any issues.
- 4. Verify refill settings: Confirm that the brine refill time in the control is set to factory specifications. Reduce if it has been increased excessively.
- 5. Replace high-level switch: If equipped with an electrical high-level switch and Err19 persists, replace the brine tank high-level switch.
