Sorry it took so long for me to update, been busy enjoying my spa. You were totally right, I had the motor wired backwards. I fixed it, triple checked everything, filled it up and fired it up and it came on for about 10 seconds then died. I had already made up my mind to call someone if I had any more trouble, so I took a cursory glance and called a pro. He came a few days later, double checked all my work up to that point and found everything satisfactory, then started trouble shooting. Come to find out that it was...a blown fuse. So basically, with your help, I got it 99% done, the had to lean on pro for the last 1%. Anyway, it's up and running now. Thanks for your help!

Thanks Dr. Spa, I'll double check the motor wiring. Since it was me that did the work, it's certainly possible (likely even) that I screwed something up. I'll feel pretty silly, but I sure hope you're right. I'll let you know what I find. I didn't actually check the GFCI yet. I think I'll operate on the assumption that it's correct and check the motor wiring first.

Sorry Dr. Spa, I should have included that initially. It's a Freeflow Passport, circa 2005. I don't believe it has a pressure switch, I believe that one (or both) of the temperature sensors (thermistors?) are also flow sensors. Maybe they measure the temperature differential on either side of the heater and deduce the flow? I did replace the GFCI plug head, but it seems like if I had accidentally reversed the polarity incoming to the power supply, the damage would be alot worse. I'll double check the GFCI wiring tonight and let you know if I find anything.

Hi There! I moved into a house that had a spa in it already. It was working when I viewed the house, then it sat idle for 6 weeks or so before I could close the deal and move in. When I moved in I found that the motor was extremely corroded, so I replaced it. Filled the tub and started it but the heat wouldn't come on. Replaced the heat sensors, one on each side of the heater, and now the heat will come on, but only when the pump is on high speed. Further, the jets button is supposed to cycle the pump through off, low, high, off. Now it will only go low, high, low, high, never off. I let it run on high overnight, even though it's supposed to automatically shut the jets off after 15 minutes it ran all night. As far as I can tell everything is connected properly on the control board, but no luck. I set it to 8 hour filtration cycle, so it's not on continuous filtration. I also tried removing the filter to no avail. The heating only on high seems like a flow problem, but since the sensors are brand new and removing the filter had no effect, I can't figure it out. The not turning off must be related, but I have no idea how. Help!
