Hello all, I am planning to buy a Beko slimline dishwasher (either DE2431 or D2731F) but need to know a very specific measurement.......I have a pipe sticking out of the floor towards the wall so I need to know the depth and height of the rear pipe recess at the bottom of these machines to make sure it will slide back against the wall......this probably doesn't make sense...even the guys at Beko didn't understand me.....Can anyone help???? Please......
