Brine tank fills with water but salt does not dissolve properly (salt bridge)

Safety first: Disconnect power. Do not use sharp metal tools that could puncture the tank.

• Check for bridge: Gently push a broom handle or plastic rod down into the salt. If you feel a hollow space under a hard crust, a salt bridge is present.
• Break the bridge: Carefully break up the crust by moving the rod up and down, allowing the salt to fall into the water below.
• Remove sludge: If there is a thick layer of insoluble residue at the bottom, scoop it out and clean the tank.
• Refill correctly: Refill with high-purity tablet salt recommended by BWT, keeping the level between the minimum and maximum marks.
• Improve conditions: Reduce humidity around the tank if possible to prevent future bridging.
