I purchased a used Leisure Bay hot tub (2001 Smart Series Model1900-s) and wired it up and noticed that the pressure switch assembly had rusted to where it was causing a leak, so I cut cut it off and ordered a new assembly. When it came in I installed it and turned it back on and hit the jets button and heard it attempt to run for a second then it died and would not cut back on. Further investigation let me to a blown 20 amp fuse, I bought some more and replaced the fuse and it came back on but I didn't press any buttons this time and just let it run and it ran for about 30 seconds and you could hear air bubbling from a jet and then it died again because it blew the fuse again. Does anyone know the reason why it would keep blowing a fuse? Does anyone have any suggestions on troubleshooting to figure out why it's doing this Any knowledgeable advice will be very helpful.
