There is star screws (Torx) on the top however when you get into the machine there are strange head screws that seem to need a special tool. Any suggestions on what the head of the screw is and where to get hold of the tool that undoes them?

Thanks Peccavi, I started out trying to describe the screw head and thought it was more confusing. I was hoping that someone would know the Jura machines and recognise what I was talking about. The head is hat shaped. It is 6mm dia (brim to brim). The 'crown' is oval 3mm x 2.5mm and stands up about 2mm high.

You don't describe what "strange head" means and give no clue.

Security drivers may be bought from DIY and tool stores.

There's a table of screw head types on this Wikipedia article...
