Jacuzzi heater and piping is all brand new, works fine all the time, this time i tried to use it, it worked fine, the water got too low i think in the spa so it just stopped filtering all together but the heater and filtering system was still on and working, just not getting to the spa. i filled it back up, flipped on the switch to get the water filtering and have the heated water going into it, but now i turn the switch on the system is working (heater unit and piping), but the water isnt getting to the spa at all, but it still sucks the water in from the spa (when the the switch is on). how do i get it to work like a spa again? all that happened was that the water level was too low then it basically shut off the water supply to the spa, but the heater unit and water switch was still on. thanks in advance.
