If the dishwasher is leaking onto the floor from the front edge but the cycle works ok the bottom door seal is leaking and needs replacing. Not a diy project as the door needs to be removed to fit it. If the machine has an internal leak it will trigger the anti flood system and continually drain and not fill (doesn't sound like that is the problem from what you say) Other poss drain hose is split after it leaves the dishwasher and is running forward under the machine. Despite age I would think it worth repairing as neff integrated dishwashers are £500 + Cheers
