I completely stripped one of the T6 screws. If you did too, they are M2 screws. An M2x6mm with a couple washers works fine.
When reassembling, it’s probably a smart move to reconnect this cable before putting the display-holding T8 screws in.
Note that a common failure point in this kind of appliance is the thermal fuse, seen in the above photo as the electronics-looking thing in the photo above, connected to the blue wire. If the coffee pot will not heat at all, check this fuse with a multimeter to see if it’s blown. It could save you the frustration of a replacement heating element that does not solve the problem.
