This pump is about 3 years old. It was working well until about a month ago and then started cutting off after about ten minutes of use. I figured something was causing it to overheat. It would turn back on after 10 minutes. I played around with the pump and it started to run longer. But then it started cutting off after 10 minutes again. Then a week ago it just started to hum and the impellor stopped turning as stated above. Its not an issue of working sometimes as it works every time with the lower voltage capacitor.
