I have a Ladylux Cafe Faucet 33 758 and the cartridge is leaking. Grohe sent a replacement cartridge so I have what I need in terms of parts, however, I am having trouble removing the handle which is required to allow for replacement of the cartridge. I have unscrewed the screw that holds the handle in place, however, I am unable to remove the handle. Help! Is there something additional that needs to be removed...like the casing or an additional screw in the handle? I'm stuck!
