Whirlpool Adp 4502 Dishwasher

We have used a Whirlpool top laod washing machine since 1992 and have given it heavy use three times per week with no troubles, We then bought an LG Dishwasher and one month out of guarantee the top tray rusted through (was replaced free of charge) now two years later it sounds like a Jumbo Jet starting up. Must get a new pump. So the wife and I went off and bought the Whirlpool ADP 4502/5/S 12 place setting and have only put through three washes but I can already testify that it is S I L E N T and it really C L E A N S and just to be sure I have captured and measured the water at the waste pipe. Not even 19 litre per load!! Very good Whirlpool!!
