So, I moved into a house in January and it came with an inground pool and spa. One Hayward Northstar for the main pump and another one for the spa. It also had a polaris pump booster that has been determined to not work.
Anyway, the pool wasn't opened in a few years so we had it drained and cleaned. All equipment worked fine except the booster. Last weekend I manually vacuumed the pool and at the end I noticed that the pump was running loudly and the sand filter pressure was very low.
Looking around, I determined that this was likely due to a clogged impeller on the pump. So, yesterday I went about the task of cleaning out the impeller. When I got home from work, the pump was running as expected (although sluggishly) and I turned off the power using the manual switch on my intermatic timer. Then I turned the power off at the outside breaker. I took the back motor off of the pump and there was indeed a lot of debris in the impeller so I removed that.
Afterward, I put the pump back together, re-primed, turned the power on at the breaker, and then attempted to turn the pump on manually from the timer. Nothing happened. Not even a hum. I checked the main breaker in our house and the gfci outlet out by or breaker box and nothing was tripped. My girlfriend and I looked at every GFCI outlet in our house and none of those were tripped. We did reset the breaker to our pool both indoors and outside, however to be sure.
I used my multimeter to check the power on the breakers and they appeared to all be working. (They all registered ~120 volts). The secondary pump will still turn on, but the main one won't. I checked the intermatic timer and the timer is no longer moving either.
Tonight, I plan on using the multimeter on the wiring beneath the insulation in the timer but other than that I'm kind of at a loss.
Oh yeah, I also checked under the motor housing on the pump and everything appeared to be ok. A little debris here and there but it was pretty dry and there wasn't any corrosion that I could see. I didn't check to see if the capacitor had blown.
