What's the exact model number?
Are you sure there's nothing getting trapped under the back edle if the cover along or near the hinge line?
One spares supplier called Ranxsoms [delete the "x"]

They publish exploded diagrams of many models of white goods. You may strike lucky and see if there are any hinge screws you could slacken that would allow you to slightly raise the rear edge of the lid
