Display shows E10 and unit indicates high salt usage or salt alarm; brine tank empties too quickly.

Safety first: Unplug the unit and place it in bypass before working on the brine system.

• Check programming: Verify hardness, capacity, and salt dose settings against the Crystal Quest manual. Reduce salt dose if set excessively high for your resin volume.
• Inspect brine valve: Remove and inspect the brine valve/check valve assembly. Ensure it closes fully and that the check ball or plunger is not held open by debris.
• Check for continuous draw: With the unit in service, observe the brine line. There should be no continuous flow. If there is, the valve is leaking internally and must be rebuilt with a Crystal Quest brine valve kit.
• Verify injector size: Confirm the injector color/size matches the resin tank size per Crystal Quest specifications. Replace with the correct Crystal Quest injector if oversized.
