Stopped working after 1.5 hrs of use
I really liked this thing, did a good job and everything worked well as advertised.  I set mine at 108 degrees for 30 min for a foot injury.  After 3 sessions of this it stopped working.  I suspect that the moisture from the hot water gets into the electronics which are located inside the tub where the water is. I had let it dry out after cleaning and wiping all the water from the inside thinking that the electronics might dry up and begin to work again. I was wrong.  Dead as a doornail.  So I opened it up to take a look at the electronics. I found no evidence of moisture on the control board at all. However I did find an IC circuit that was fried (see Photo) it also smelled like it had melted. So theres that.
