Brine tank overfills with water or water level is unusually high

Safety: Disconnect power and close inlet valve. Be prepared for brine spillage; wear gloves and eye protection.

• Check float assembly: Inspect the brine float and safety shutoff in the brine well. Ensure it moves freely and is not jammed by salt bridges or debris.
• Inspect refill valve: If water continues to enter the brine tank when the unit is idle, the internal refill valve may be leaking. This requires valve head service.
• Verify settings: Confirm that the brine refill time is set according to Grünbeck specifications.
• Check drain connection: Ensure the drain hose has an air gap and is not submerged in standing water, which could cause back-siphoning.
