How do I open the delonghi bar32 machine.

How do I open the delonghi bar32 machine.

My delonghi bar32 espresso machine stopped giving hot water. I think the issue with the heating coil. I've got a new one but now I need to open the top and replace the unit. I see 4 torx T20 screws that I have unscrewed but would like help in getting the thing opened.
