Fisher & Paykel bottom door seal & Classique wall oven door hinges

F&P dishwasher - Apparently this model is obsolete now, so cannot get parts?! And as the seal is pressed into the door in the factory, apparently I need to replace the door. So I guess I'm looking for a second hand door if anyone has one? (brushed silver) I also have a Classique oven door that doesn't close tightly anymore and apparently need new hinges (not a seal). I have had an appliance repair service man around to advise this, but all they can suggest is that a need to buy a new dishwasher.. And the oven will cost me$250 for the hinges. I'm sure there must be second hand parts available somewhere. The dishwasher is approx 10 years old and runs like a dream. Open to suggestions as to what to do with the oven. Possibly cheaper to replace with second hand oven?
