Salt forms a hard crust or bridge in the brine tank, with a hollow space underneath.

Safety first: Wear gloves and avoid excessive force that could crack the brine tank.

• Locate the bridge: Gently push a plastic or wooden rod down through the salt. If you feel a hollow space before reaching water, a bridge is present.
• Break the bridge: Carefully tap and poke to break the crust so salt falls into the water below. Do not use metal tools that could puncture the tank.
• Remove clumps: Scoop out large, solidified chunks and discard. Refill with fresh, dry tablet or block salt recommended by Kinetico UK.
• Prevent recurrence: Keep the salt level between the minimum and maximum marks and store salt in a dry place.

Warning: Do not pour hot water into the brine tank to dissolve bridges; rapid temperature changes can deform the tank.
