Hi,
My wife and I just purchased a Maax Spa 103 California Cooperage Spa. It has worked amazingly all week we've had it and we've loved it. This morning when we came out it said Pr on the screen which I read in the manual meant "Priming Mode". The Jets are all pulsating high/low/high/low nonstop and non of the buttons make it stop for more than a few seconds. I let it run for a long time, then I unplugged it for a couple hours. When I plug it back in it immediately begins pulsating Jets and says Pr on the screen again. The filter is all clean, it has plenty of water in it. We tried running the hose into the filter hole as some websites suggested to run water through it, and nothing seems to take it out of priming mode so we can use it normally. Any ideas on what to do? Thank you!!!
