I'm slightly further along the same path as you with my whirlpool oven!! I've got my new hinges, managed to get the old ones out ,but can't work out how to get the new ones in.
There is a video on the bosh website that's really helpful in showing how to remove the door;

If you have any luck with further instructions, could you post them here & I'll do likewise?
Cheers, Mandy
