Diplomat ADP8322 steam from one side at top door?

Hi All,

As above the door doesnt seem to be fitting tight flush on the left side and that is where steam seeps out, I've changed the hinges thinking they may have been bent (probably were ok) and the lower seal, the top seal looks in good condition but am stuck as to how to get the door to lock tighter on the left as it is on the right. With these machines there is only a central pull bar that holds the door in place when closed.

Thanks
Smithie
