I had the pump running on high today with the heater going and all was fine. A few hours later I went to go swimming again and noticed that the water had cooled off and nothing was coming out of the returns. I checked the pump and sure enough it was not running. The main is fine as I am getting power to my swg. When I turn the main off/on nothing happens. The motor portion felt hot but since its not something I normally touch I don't know if that's normal or not. I don't know how old the pump is but we've been here four years. There is no timer, just a high/low switch. The pump doesn't work with either setting.
Could a dry pump cause this? After having a pool liner leak repaired two weeks I noticed a lot of air in the pump. It turned out to be an air leak near the skimmer valve which I had fixed last week. In the meantime however, I found the pump having difficulty maintaining prime. A few times the flow of water stopped and I had hot air coming out when I opened the lid.
Assuming that it's not an electrical issue, which I will have checked tomorrow, would I need to replace the motor or the whole pump?
