I was trying to get my brother's Jacuzzi working as its been left unused for several years. I just fixed a leak when I replaced his front pump housing which had a crack. We filled it and turned it on and are getting OH codes and FLO codes. His model is a 2005 J-375. The temperature kept rising and the unit shut off (breaker tripped). We also saw a leak at the heater element end and re-attached the hose to it (not sure if air getting in caused any problem). One pump stopped working as well.
Any ideas?
