How do I disassemble my Kenwood Cafe Retro coffee machine?

The pump on my Kenwood Cafe Retro machine is not working. I’m trying to check if it’s just a loose wire or if I need a new pump but am struggling to access the internals of the machine. I have removed all the screws that hold the housing in place and just need to remove the screws that hold the steam valve lever arm in place. You can see the tips of these small screws inside the housing in the image below (arrowed).
