Salt forms a hard crust (salt bridge) in the Cillit brine tank and water level stays low underneath

Safety: Wear gloves and avoid striking the tank hard, which can crack plastic.

• Identify bridge: Tap the top of the salt bed with a plastic tool. If it sounds hollow, a bridge is present.
• Break the bridge: Gently push a broom handle or plastic rod down through the salt to break the crust, allowing salt to fall into the water below.
• Remove caked salt: Scoop out heavily caked salt and discard. Refill with fresh Cillit‑approved tablet salt.
• Prevent recurrence: Keep the salt level between one‑third and two‑thirds full, and store salt in a dry place.
