Is there a manual for a Hoover D7190 Super Crystaljet dishwasher?

We inherited one from a friend, and it worked mostly, till the bottom edge of the door suddenly started to leak. I need to know (a) if there is some cleaning procedure we've neglected, (b) how to get a replacement door seal if that's what it takes, (c) if we're using it properly. Most of this would be covered by a manual. Hoover's website is incomprehensible, and Google has let me down. Does anyone know how I can get hold of this thing?
