Bosch WFB 2005 - how to remove front panel?

The power switch on my washing machine does not engage the power. This is a fault with the white plastic switch in front of the electrical switch, and I guess, a missing spring.

How do I remove the front panel? There is a screw behind the detergent drawer and a tab at each side. Where are the remaining tabs? I presume they're inside, but I cannot find them.

Thanks.
