I have my Hamilton 780 tub set on the winter cycle, (F3 and C6). I’ve noticed that for the last week that not everytime, but at least once a day, i go check my tub and the waterfall is not running which tells me that 24hr circulation is not working.
THe weird thing is that if i turn the temp up one degree,from 100 to 101, it will turn back on, but if i turn it back down, to 100, it will shut back off. Is that normal?
