@jammieallen,
Hello,
On checking all parts make sure you have Gasket ,Nozzle and fill plug.....check the hole on the Gasket machetes with the Nozzle and the Venturi Nozzle assembly....very important is to clean Nozzle and one last thing is fill plug is put back in the center of Venturi Nozzle assembly
When starting up W/S first Cycle is Fill and Second Will be Brine Draw and will draw all water out of tank if everything is installed correctly
Water will be Milky and Salty after completely all cycles ....run water after completing all cycles at bath tub until all salt is removed
good luck
