    Spa Air Blower turns off after 5 Minutes

    I tried 3100 and got up to 8 minutes. Tried again at 2800 and after 22 minutes I turned off. So, ultimately the back pressure is from too much water flow/pressure. But, my VSP is smaller than my previous single speed and that didn't overheat. Thanks ajw22, I consider this a win.
