Sometimes dishwasher leaks a lot of water & other times none. I was thinking it may be the rubber seals aroudn the door & on the inide of the unit next to the door? The rubber seal along the left inside of the unit finsihes at the bottom of the unit, and at that point there is a 5cm piece of rubber seal which is 'only patially' attached to this & it lies on the flloor of the inside of the unit?
