I have been getting FLO error on my jacuzzi J-370.
1.) I first pulled the 2 month old filters off. Pump turns on and i get full waterfall. still get FLO error
2.) I pumped hose water into filter inlet. still get FLO error
3.) I jumpered the flow switch. within 30 seconds I can hear water boiling at inlet to flow switch. I get OH error and then it shuts off.
Where do I look next?
