This week we had a crazy amount of rain. The area of my yard where the pool equipment is was flooded due to heavy rain in a short period. I heard the pump trying to come on and then going off about 10 seconds later. I turned off the breaker and let it rest until the area was more dry and then pump was able to turn on and function properly for a few hours until it cycled off (although it sounded odd).
A day later (and much drier) the pump comes on but turns off after about 10 seconds of humming. It sounds like the motor is really straining and slows down as it starts to prime. See video:
The squeeks at the end of the video are actually birds chirping and not the pump. =)
I opened the basket and checked the impeller for any obstructions but it was clear.
Any idea what is going on? Anything else to check before looking for someone to service it?
Pool is 10k gallon, sand filter, chlorine.
Pump: Hayward Tristar 1.5 HP, 220V.
