I think I had a bubble. Every once in a while it gets hot when it shouldn't and I'm pretty sure that's why. Possible my pump is going bad. Those are the only two things left, I think.
@@RichardGonzalez-oo7dr Good question. It's been sitting and I just got it back out to work on it again. I did get a new thermal switch and I'm going to try that this week.
