Salt in the brine tank forms a hard crust or bridge above the water level.

Safety: Wear gloves and eye protection when working with salt and brine.

• Check for bridge: Gently push a broom handle or plastic rod down into the salt. If you feel a hollow space under a hard layer, a salt bridge is present.
• Break the bridge: Carefully break up the crust without damaging the brine tank. Do not use sharp metal tools that could puncture the tank.
• Remove clumps: Scoop out large, solidified salt pieces and discard them. Refill with high-quality tablet salt recommended by Grünbeck.
• Prevent recurrence: Do not overfill the tank; leave space above the salt. Keep the installation area dry and well-ventilated.
