I recently purchased a antigua spa used. Spa worked great and heated fine. We drained the spa and brought it home ,filled it up and now no heat. It will give an overheat code. Do i possible have an air pocket within the heater ? i have purged the pump.
Hello, how can I help you today? when you first start it up, does the pump run and pump any water?
yes the pump runs and wwater comes out. no heat though.
how long does it take before you get the overheat code come up?
ok, is it possible that you've got a plumbing valve that may have closed down on you during the move, if that's what has happened it can be restricting the water flow enough to overheat the heating element and trip the high limit sensor. The other thing i'd have you try, is when you start the spa up, gently touch the stainless steel heater housing to see if it's actually getting too hot or whether it's just false tripping and not actually overheating.
i think i have figured it out. I removed the output side thermosensor on the heater element and a LARGE amount of air escaped. After that the circulation began when I turned it on. I started it this morning and the unit had heated the water two degrees in about one half hour. I am going to check it at the end of the day and see where I am at.
ok, an air lock was my first assumption, but when I first asked you had said that the pump was pumping water and when that is the case it normally means there's no air lock, but if you did get air out then the pump was air locked and i'm sure that was the only problem, it happens a lot when spas are drained, might happen again in the future just for reference.
yes, air lock was not at pump as i had purged that. It was actually air bound in the heater. The jets did in fact run the whole time, however there was no circulation with the pumps shut off.
that's strange, and the pumps that were running, they are the same one that is pushing water through the heater, i've never seen a heater maintain an air bubble if a pump was forcing water through it. Just wondering if your jet pump might have been pumping but the circulation pump that pushes water through the heater was air locked.
