Just bought a second hand Hotpoint Aquarius DF62 dishwasher about 2 1/2 yrs old but the drain pipe at the back is smaller than the standard size and will not fit onto the waste nozzle under my sink and I have no stanpipe fitting capability. Hotpoint claim that they have never changed the size of their outflow pipe but it's not the same as the new machines. They also have no converter kit. Can anyone out there give me some clues as to how I can get my waste pipe connected? Help!! Relying on you guys!!
