Filter Cleaning - Unable to close the lid

[rkrgk]

Thanks Ben.
I had attached the picture with my previous reply(but for some reason, it looks as though you were not able to see it). And the manual you mentioned is the one that I referred to when taking apart the filter grid and putting back together. From the picture you posted, it is similar except that the pressure gauge is sort of protruding on top and the top lid is a bit more taller in my filter. Let me try to attach the picture again.
