Hot tub troubleshooting?

Question

Our hot tub won't heat up past 72. We push the temp button but nothing happens. Everything else about the hot tub works.

Any suggestions on what to check so we don't have to pay someone to come out??

Answer 1

It's the hot tub that's helping you stay happily in love! LOL

The hot tub has a built-in heating element, it's either that, or the control for it that is on the fritz.  If your handy with an electrical meter you can access the wiring and try to trouble-shoot it yourself.   If there is any warranty left though, you may void it if you mess with it yourself.

I'd wait for the repair person.

Answer 2

check reset on your high limit
