May be a simple solution. Salt may be bridged. Do not poke or shake. Pour 3 gallons of water over the salt in the salt brine tank. Pour onto one spot. If this is your problem, the water level in the tank will now disolve the salt and be able to regenerate or recharge the system. SUGGEST> do not add salt until tank is almost empty and then only fill 1/2 of tank. Good Luck
