Welcome to our forum.
Well, like I said, after tightening the 220 cable coming into the box,,,,it won't start up. Just makes a small "click" noise when I push the jet button, and does nothing. From the very first, I suspected a pump going bad, and have had my hand on that pump numerous times when trying to get it working. Not even once, have I felt vibration or humming coming from the pump itself. The ONLY place I did feel (and see) vibration,,,,,and this has been numerous times, was on the main panel box (that includes the aluminum case itself, as well as the the wires and main circuit board). Right now, it's doing nothing.Are you sure there isn't something else I can try?
Ok,,,,,have a lot of stuff going on,,,,,,just got back to hot tub. I took a pair of thin "channel locks", and was able to get them between the motor and the pump housing. The shaft turned freely, and I could feel a little "play" as I turned it one way, then the other. I feel that the motor is turning freely, BUT, I was going to pull the pump anyway, as you suggested. Looked like about a 10 minute job to me too! I closed off my valves, and was getting ready to loosen the bolts where it mounts to the board holding it, the blower, and the main control box. I was wondering if they were screws, or had nuts on the under side when I thought about that big fuse in the control box again. I stopped everything, got my meter, and checked the fuse in the holder. No continuity,,,,so I pulled the fuse and checked it, and again, no continuity. Sometime after I had tightened those 220 wires going into the box, something blew that fuse. It is Memorial Day, and almost 6pm, so I am going to wait until tomorrow and get another fuse, and see what it does then. Right now I have power on the top side controls, and the spa light, even with the bad fuse,,,,,,but the motor won't come on, just hearing the clicking. Hopefully, when I replace the fuse, the motor will come on again.
