the blower motor attached to the the 4 jets in the lower part of the spa will not blow for more than a couple of minutes before overheating. first thought it was the blower itself and changed it out for the blower for the upper jets and that one did the same thing. i then took the jets out and ran pump in spa mode with the blower on for an hour without a problem. I was hoping to clear an obstruction with the jets out but when i reinstalled the jets the blower cut off again. i have my inteleflo vsf pump set at 35 gpm, anything higher than that and the blower motor will blow off the pipe. So i am pretty sure there is some kind of obstruction in the air line. Looking for a suggestion on how to clear the obstruction from the air line. the blower motor is approx 40 feet from the spa. the pool is only 1 year old and the blower used to work. i am having trouble getting the plumber to come out so i am trying to solve the problem myself.
