Hi guys, I could really need some help. I recently bought a house and it came with a 2005 jacuzzi j345. I'm trying to get it up and running, and have no idea what's wrong with it. Originally once I powered it up, it just kept blowing the breaker. I had an electrician friend look at it and he had me replace the circulator pump because it was supposedly seized up. It now runs but flashes fl1 code. It will run for maybe an hour then trip the breaker again. All my pumps seem to be working. I have replaced the filters, replaced the flow switch and tried all trouble shooting I could find on this topic. Any ideas?
