Display shows LO SALT or LOW SALT even when salt is present in the brine tank

Safety: Wear gloves when handling salt and brine. Unplug the unit if you will be working near wiring or sensors in the brine tank.

Steps:

• Check for salt bridge: Use a broom handle or similar tool to gently push down into the salt. If you feel a hard crust with empty space underneath, break up the bridge so salt can fall into the water.
• Inspect brine level: Ensure there is several inches of water at the bottom of the brine tank. If the tank is completely dry, the brine refill may not be working.
• Clean brine well: Remove the brine well cover and float assembly. Clean out any sludge or salt buildup that could interfere with sensors or the float.
• Check salt sensor (if present): Some Whirlpool Pro Series models use a salt level probe or optical sensor. Inspect the sensor for salt crust and clean with warm water. Ensure the wiring is intact.

Resolution: If LO SALT persists despite adequate salt and a clean brine tank, replace the salt level sensor or brine float assembly as applicable to your model.
