Removing "strange" screws integrated dishwasher

[MasterMark]

Hey all,

just moved into a flat with an old integrated Bosch dishwasher. Has a pump problem, so trying to take it out to see if I can fix.

But the door seems to be held by some very odd (at least to me) screws. They look like hex, but allen keys don't work. On closer look, seems like the insides are curved. Photo attached with a drawing to explain what I mean! I have no idea how to unscrew them. Anyone with any ideas?!

Thanks!

They are star or torx bit screw heads.


Best to get a set like this it will cover most of the odd screw head types.

Awesome, footprints, thank you. After you posted I found another screwdriver set which has the right screw heads which my other set didn't.

Problem solved, thanks!
