Help - Rainsoft Water Softener

[westindies]

Hello everyone,

My rainsoft water softener, model AMB744 is not using the salt in the brine tank and the motor seems to be running non-stop. I removed most of the salt from the brine tank and I can see the brine solution in the tank, but it's not moving.

Any suggestions on how to trouble shoot the system? I've attached a couple of pics on the system.

Thanks for your response.
