Hi folks. I'm a brand new spa owner. Bought a home that has an indoor spa. I've got little experience with spas. I went to get things set up today, and everything went well except... the heater doesn't work. It's a Hayward C-Spa XI 11. The breakers are on, the pump runs (and appears to have good pressure. The valves are open. The filter is a clean one. Everything else appears to work as it should.
Any ideas or thoughts?
