Why won't the filterpack door close on my Mars FLAVIA Barista Coffee Maker?

If the filterpack door on your Mars Coffee Maker will not close, it may be due to improper reassembly or insertion of an espresso pack. Remove and replace the filterpack door, and ensure you're not inserting espresso packs (red nozzle) into the filterpack door, as they can only be used in the espresso pack door.
