Welcome to our forum.
Sounds like you've got an air lock. What model Sundance? Some have two speed pump no. 1, others have just one speed pumps. If you have a model with a two speed pump, your air lock could be in that pump or the circ pump. If you have one of the 880 models with the high flow circ pumps it most likely is the circ pump. Don't have any experience with that type, but with the other..if you lift off the diverter valve handle and loosen the valve itself (unscrew) just a little, any trapped air should escape. Also, try running without filter to free up.
Hey Tony. I've got a Bahia. It has a 1 speed and a 2 speed pump w/ozone and a circ pump I believe. (new owner w/out manual???)I'll try the diverter. I found a manual put online by an owner of a different model (portofino) Sundance and it says something very similar.Thanks...I'll give it a whirl. Will update soon.
UPDATE: Tony, couldn't figure out exactly how to loosen the diverter (not even sure which one it is) but found a SWEETWATER MANUAL online and it suggested to put hose in covered end of where filter fits and turn on for 30 seconds. Also started without filter in. It BURPED my tub! A big air bubble came out, restarted tub and no FL1 error! So, do I shut power down and reinstall the filter and run overnight to heat?
Expect that to be a possible issue whenever you drain and refill. Get an owners manual, if you can't locate one on Sundance's website (they have a lot available, so look again) get one from your dealer. They should have delivered you one with the spa. To do the diverter valve trick, simply lift up on the handle and it will come off relatively easily, Then just unscrew the part right underneath the handle, it's threaded to hold the valve in place. Make sure the pumps are off if you do remove that cover, or you'll have your own "Old Faithful" display.
Maybe your diverter's are different for that spa than for my Optima. When I lift off the control, I see the square thing that the cover sits on, but it's surrounded by this big plastic round cover that has some grip ridges on it. Grabbing that cover and unscrewing it will allow you to see or remove the diverter valve. I checked Sundance's website by clicking on customer care, then owners manual, and there were probably 60 or so PDF links. The North America section had manuals going back at least 10 years. Maybe your access isn't set up correctly. You'd need Adobe Acrobat to open the manuals, but I'd think even if you didn't have it on your pc you'd still see the links. But I might be wrong there. Do you have Adobe Acrobat on your pc?If not, it's a safe, free download.
Did you fill the tub running the hose through the filter compartment? My tub does has a bleeder valve near the top of the lines to bleed air off, I don't know how common that is.
Yep....did fill it through the filter. Honestly, the suggestion of putting the hose with a rag around the end to the OPPOSITE END of the filter housing where you're supposed to fill it (screened end) worked perfect. It was just like burping the tub..a big bubble of air came out within 10 seconds and then nothing for the remaining 20. Started up the tub and no problems. I'll look for the bleeder valves...I thought I saw something like that under the hood.
Brewman...I SWEAR I tried that exact same thing several times at my pc at home and I had my wife try on her laptop too and not a single .pdf came up, NOT ONE!!! Then I come to work and do it, BAM! No problem. Thanks for pushing the issue. Now I have A MANUAL!! Could be dangerous!
I tried yesterday also and there were no pdf files. They must have been working on the site at that time.
