I have an old Grohe bath faucet. The hot water side will not open all the way. Not sure if it is a washer issue or what. Each side has a hexagonal insert (at least I think), with GROHE labeled on each. I assume I am to pop it out which would expose the screw beneath. I can't seem to even get an eyeglasses screw driver to slide between the seam.
How do I remove the handle? I am including a picture.
Thank you all.
