Our new dishwasher arrives this evening. The one that came with the house no longer fills (yes, I've checked the fill valve float and other things), so off it goes. I can't say I'm unhappy -- the thing doesn't clean as well as it should and I have no idea how old it is.

As a side note, I think it was a home-installed job. When we had it checked by the plumbers before we moved in they found that it wasn't hooked through to the garbage disposal and one of the inlets was sealed off with a Pepsi cap and black electrician's tape!
