While the pump is shut off. Don't ask me how I know that.
Funny thing,,,,I just shut off the Spa for like the 3rd time within 4 days for about 10 mins....Took both filters off and took the Nature2 out of the filter and turned the spa on and it works now.........Its was 76 degress and now its 92 degress.....No More Flo Light Blinking on and offStrange that it starts to work after about 5 days of not warming up......Glad its working and saving $90 for service fee........JT
Johnny, a very common cause for for that flo message if you have not recently refilled is a clogged filter. if you pulled the filters and turned power on with the filters out and the flo went away, it is likely the circ pump filter was clogged. unfortunately your dealer and jacuzzi should have asked you to take your filter out and see if the flow goes away. first thing i ask when someone has a flow message, saves me and the consumer time and hassle if it takes care of the problem. I always ask the customer to take out the filter even if they say they are new or i just cleaned them. I had to learn the hard way by many wasted trips to a customers house to find out the filter was clogged. not saying that was the reason your's stopped but generally if you have flo and pull the filter out and the flo goes away, it's the filter. and as to the service charge this is more than likely straight from your dealer, as Jacuzzi's warranty cover's part's and labor. we do not charge a travel charge but every dealer is different. shame on him for not disclosing whether he charges for travel at time of the sale.
I recently bought replacement filters off ebay for half the price of the factory Jacuzzi filters, and exactly the right fit. The only difference is the filters don't open in the center, which would be a problem if I used the N2 system in the traditional manner.
