Hello,
I have a '07 Altamar that I am having a problem with. Recently we started getting FLO notices on our control panel and the hot tub not holding temperature. Did a bit of reading online and the owners manual and popped out our filter which was due for replacement to see if it was causing problems. Popped the filter out and ran it for two days and FLO messages went away and temperature held.
So it was time to do our semi-annual water change anyways drained hot tub and added new filter. When I went to power the hot tub back up I only get this on the control panel " - - - -" and nothing else. Tried cycling the power a few times no change. The manual was no help as it says call service technician. Any suggestions on if I need to bleed the system of air ?? It is under warranty but, I hate calling someone out for something I can troubleshoot in 20 minutes.
Thanks!
