Took the lever apart and lubed the cam and gaskets. Boy, that thing was jammed in there. It's like the gaskets inside the unit clung on to the lever, so when I was turning the lever I was turning the washers in the unit too. Anyway, after a little frustration loosening everything up, everything is back to normal. Thanks for the help, everyone.
Did you lube the actual valves themselves where they slide around in the body of the group, upper group valve and preinfusion valve. This is quite important for continued free movement and minimising cam/pin wear. One has a square and the other a triangular profile which slides up and down in round holes at the top and bottom of the group. it does require disassembling the group (mainly so you can properly dry the surfaces before using dow 111 on them), but it's not that difficult.

No problem. The point I meant was that the areas to be sure to lube are between the cam and the valves they actuate; where the pins rub on the cam as shown in the video. That should be done two or three times a year, and definitely every time after backflushing with detergent.
