Can you post the full model number please. It should be on a sticker on the inside of the fridge behind the salad box.
Thanks for that. Ive found it now. Its actually badged up Neff rather then Bosch, Still the same company but they use different parts list.
On this they use spring loaded door hinges. You will find these are the fault here. That will be why its not closing correctly. You need to replace the door hinges on this and you will find this will cure the fault.
Now they come as a set of 3 so replace all of them and the part number is 00268699 if you need it.
If you need anymore info just get back to me.
Door seals dont cause a door to stay closed. This is done by the hinges as the seal just sits close up the cabinet when the hinges are fully closed.
This is going to be hinges as its not uncommon for them to fail like this. Ive replaced loads of them in the past for this kind of fault as they are spring loaded hinges.
