Thanks for all y'all help. I have the mpv working again and I started I new thread in the just getting started section where it is more relevant. THANKS
I was afraid we would have to cut pipes to change it out. That's a relief! ...
This is the first I've heard about going only one direction with the valve. I don't understand what is affected by this? You're lifting the 'manifold' off the gasket so it's not that, is there a seal in the cover that it affects maybe?
on my pool, I did have to cut pipes, and I dreaded it, but once I got started it wasn't so bad. I've replaced the multiport valve twice now, I discovered the hard way WHY you don't EVER lift the valve handle while the pump is running. I found instructions for working with PVC pipe but I never found the specific pool plumbing help I wanted, so I just did it, and it worked out okay. The hardest part was choosing the order of things so I didn't get in my own way with other parts.
This was my first thought when reading about your problem, that you may have had the little "walls" the spider gasket fits into, break like mine did. That required the lower valve body to be replaced, which required pipe cutting.
I see from both your threads now that you got it fixed, what did it end up being? Sounds like you were able to just replace the valve selector and top cover set? Hopefully got some new screws too. Another thing I was considering is that your selector shaft might be sticking in the cover.

When I first heard of it, I thought, "Well, I'm not sure I understand the DEFINITIVE reason but it does make sense to seat and then re-seat the valve by sliding it consistently one way.This is the first I've heard about going only one direction with the valve.

Sorry, you're right, that was written in a hurry. What I was trying to say was that the 'spindle' or shaft that goes down through the center of the valve top, with the selector handle on top and the 'diverter' or whatever it's called, on the bottom, that might have some friction preventing the spring from putting full force down on the spider gasket. You might need to lubricate that shaft.I'm not sure what part the " selector shaft" is, are you talking about the outer handle?./.
