water softener mod #625.348471/91 has tub half full of water.

Start with cleaning the nozzle and Venturi. This should not require any tools, and can be disassembled and assembled by hand. Take note on how things fit before you remove them. Wash the components in water. Use some vinegar. Make sure there is no deposits, salt, rust, calcium or debris.

Then check the float in the salt well in the tank. The float should be able to move up and down, and the hose should be able to inject water in the tank and suck it again.

Then shut the water supply, drain the house (open the lowest lying faucet in the house), then disassemble the cam gear and rotor from the valve head. Check all the seals and gaskets and that there is no wear on the smooth side of the rotor.

Run the diagnostics as per the manual, and make sure that the cam gear moves well. If the motor is skipping and making a clicking sound and failing to move the cam gear, then replace it.

Replacing all the gaskets, the rotor, the cam gear and the motor should solve most problems, and only cost 74$ Cdn. That is provided that the nozzle/venturi are clean, and that there is no obstruction to the float assembly.

Check for the formation of a salt bridge, specially in humid environment. Tap the side of the tank and see if there is a hollow sound at some spot under a solid sound. Use a broom stick to break it.

Once every six months, get a water softener cleaner (basically a sulphite powder that removes iron deposit. You can buy it at Canadian Tire or other hardware stores. It is more expensive at Sears, so avoid buying it there.

Every year or 18 months, try to remove all the salt from the tank and wash it. You can use warm water, and a wet/dry vacuum to remove it.
