Softener produces salty-tasting water immediately after regeneration

Safety first: Do not drink or cook with water that tastes salty until the issue is resolved.

• Run additional rinse: Manually advance the softener to the rinse stage and allow it to complete a full rinse cycle. Then flush household lines by running taps.
• Check settings: Verify that brine draw and rinse times are set according to Viessmann specifications. Increase rinse time if allowed.
• Inspect valve seals: If salty water persists, internal seals may be leaking. Disassemble the valve head and inspect seals and pistons for wear.
• Replace seal kit: Install a new Viessmann valve seal kit if leakage between brine and service ports is suspected.
