Grünbeck Brine Tank Overfill

The brine tank overfills with water, or the water level is unusually high.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck brine refill valve, Defective brine float assembly, Incorrect refill time setting, Siphoning from the drain back into the brine tank

Safety: Disconnect power and close the 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.
