When you say is it isn't filling..
Safe to say the lid is making no difference.
snipped loads
Never had a fluidmaster apart..but I think the upper black cup thing
should come off and there will be a diaphram washer and a plastic
reducer there.Just check those.


I had to change one of these this week, as it was leaking, and to
compound it, the overflow was leaking, so the bathroom floor was soaked.
Anyway, i tried to take it apart to see what type of washer it had, and
I just couldnt prise the top off.
I gave up and went to a plumbers merchant who said they hadnt seen one
the same as that before (just the same as in the pic,) but sold me a
generic replacement, which JUST fitted in the available space, though
the OP's cistern looks to have a smaller syphon than the one I had to
squeeze it past.
Cost around £12, and once fitted worked well.
Screwfix do one very similar:
