Last night went out to check the equipment, and the infloor motor wasn't running, but was exceptionally hot.
This morning I took it apart, hoping it was a clogged impeller. Though there was a small amount of debris, the impeller bolt was entirely loose. Strange. I thought that could have been the cause of the motor not running.
I cleaned the debris, tightened the bolt, and...nothing.
Checked the capacitor, and while I'm not sure if it's bad, all the leads were fine. I also know that a blown cap is a sign of a bigger problem anyhow, so I tend to not view a replacement as a "fix" that lasts more than a few days.
The motor is a little over two years old.
I have my pool guy coming to look at it, but these motors generally last me longer than two years, and I tend to hear the windings crapping out.
Is it possible the loose impeller bolt caused something else to malfunction inside? I replaced the shaft seal about 3 months ago, and everything looked fine at the time.
