I have a 33k gallon pool with a Hayward S244T 300 lb sand filter and a Hayward 1 HP Super Pump (Model: C48K2N143B1). I've been having problems with the pump recently.
It started a slight hesitation when turned on, like the pump was trying to turn over but met resistance. This only happened for a split second and it was fine after that. It had been doing this for a while but it was slight so I didn't pay much attention to it. More recently, I had a problem with an air leak (which I'm assuming is related) where air would be let into the system only when the solar panels were on. Because of this, the pressure was around 11 PSI rather than the normal 20 PSI with the solar panels on and a lot of air bubbles were coming out of the jets, continuously. I read on either this forum or another pool forum that it occurred only with the solar panels on because of the difference in back pressure and that air was being let in somewhere in or around the pump, rather than through the solar panels like I thought. In the past few days, I figured out that if I turned the pump on with the solar panels on, I could hear the air going through the pump like it has been. But, if I turned the pump off for ~2 seconds and turned it back on, it would function normally with the pressure around 20 PSI as it should be. However, the pump struggling to turn over on start up was getting worse. Yesterday, when I turned the pump on, the buzzing resistance sound stayed for at least 4 seconds before finally turning over and moving water as it typically would. This morning, it did the same thing, but this time, it buzzed and wouldn't turn over for probably 6 seconds, and then stopped completely. I shut the fuse switch off and went down into the basement. The fuse box for the pool/related things has 8 breakers. Breakers 4 and 7 were tripped. I shut them off, and I turned 4 on, and when I flipped 7 back on, they both tripped again. I flipped them off and back on again, and they stayed on this time. However, the pool pump is still not doing anything when turned on and the breakers are staying on. Has the pump died? Is there anything I could check or repair to potentially fix it? I can't put a number on the age of the pump but it is at least a few years old.
Thanks in advance,
