I have had endless problems with dishwashers, noisy, faulty, leaking, and unreliable. This time I was going to research them fully, spend the money and get one that works.  The reviews all seemed to favor the Bosch - so I have one installed now.  The first time it was turned on I thought it wasn't working, it was - it was just so quiet !! This still surprises me now.  It cleans well, has a good capacity, and the tech that installed it (who used to come and fix all our other dishwashers) was keen to look at it.  He doesn't see many Bosch machines, apparently, they don't fail much so he doesn't see them!!
