Hi PF team,
My water is looking great. I probably have a leak somewhere but can't find it in the liner. I test FC and pH daily and often have to add acid to keep pH right.
So, here's my new problem. My pump is on a timer. I've noticed a few times recently that pump is turning itself off before end time on the timer. Sounds like the pump is overheating, maybe? Other thoughts? Is it time to call my pool guy?
Thanks.

What do you mean, "turning itself off"? Is the breaker tripping? Is the pump turning off, and then after 10 - 15 minutes back on?

The latter behavior would be typical of a pump turning off on an overheat safety.

The pump turns off before end time per the timer. It has not turned back on but I don't know how long it's been off. I've just noticed that it is off "early" so to speak. It is not tripping the breaker, and I have been able to turn it back on as soon as I've realized it's off. Hope that makes sense.

I can't tell anything from that description. Can you turn the timer off, and leave the pump running? If there's a problem with the pump, it will shut itself off at some point. But, if the problem is with the timer, the pump will run uninterrupted.

sorry I'll try again....for example, timer is set to turn pump off at 5pm but at 3 pm I notice that pump is already off. Are you suggesting that I remove "off" clip on timer and see if pump runs indefinitely?

Yes, or remove the timer from the circuit completely. He is trying to rule out the timer being the problem. If the timer is not in the circuit and the pump still shuts off, the problem is most likely with the pump. If the timer is not in the circuit and the pump does not shut off, the problem is most likely with the timer.

The problem is the timer. My husband said that he tried to move or did move the pointer (which directions on the timer say NOT to do) when trying to set timer. We have a T104R timer. Suggestions on fixing this?
Thanks.
