OK, so digital cookies don't taste too good...sorry.
I got the screen out. I had to pull the let side plate and found that the plate had been sealed with grey gasket sealer. The sealer also had "glued" the suction screen to that plate. It appears as though the screen is designed to be spring fit between the left and right plates and is meant to be removed from the right side. I will replace the plates with sheet gasket material and not the liquid stuff. Should work fine.
The ggo news is that the screen was clean so the guy before me really did do maintanence as he said. Hope all continues to go well.
Thanks to all for your help once again.
Peter
