Hi there.
I read this: https://www.workshop.bunnings.com.au/t5/Kitchen/How-to-fix-a-kitchen-tap-handle-that-keeps-falling-off/m-p/176077
But I am not sure how to tighten the nut? Looks like I need a new handle?
History and what happened: I had to replace the cartridge (minor leaks) so I have pulled the handle relatively easily (WD40 and little pulling, etc). So, the new cartridge is installed and now the handle is loose obviously. I can't un-tighten or tighten the nut...Looks calcification or something? The nut is not going into the cartridge.
Please help if you can.
