Do I understand correctly that you did the installation completely by yourself?
Yep. What CFB said. This is about my sixth dishwasher so I'm feeling pretty [-]cocky[/-] proficient.
We don't have a receptacle in the hole, but the builder's electrician helpfully installed a wall switch under the sink. So you just turn off the switch (or the circuit breaker), unscrew the wires from the old, and screw them onto the new. It also helps to ensure that the wire (laying on the ground) doesn't entangle itself in the new dishwasher's wheels when you roll it under the counter, but I don't care to discuss how I learned that.
Our water supply line is hard-piped copper to a compression fitting, but I've also used braided-steel hoses. Ironically the only water-supply leak I've ever had was a braided-steel hose that I hadn't gotten around to replacing at its 10th anniversary. It was 10 years four months old.
Most manufacturers include spring clamps for the drain hose connections, but I prefer to really tighten down a hose clamp.
What did you do with the old one?
"Ask us about our low low shipping fees!"
To qualify for the Maytag "fireball recall" $75 check you have to sign a "Proof of Destruction" affadavit with the model & serial number of the old one. (The recall part is an electrical connection in the door that gets soaked with rinse aid and catches fire. We never use rinse aid.) I'd feel bad if that model/serial turned up in the forensics of some Craigslist buyer's home fire, but I'm toying with offering cheap dishwasher replacement parts over Craigslist. Otherwise we'll ditch it in bulk pickup, where JG will probably pull it out of the landfill and set his own kitchen on fire.
What is the advantage of stainless steel interior? Around here everything seems to rust, even stainless.
Then it's not stainless!
Believe it or not, stainless is more resistant to chemical attack (dishwasher detergent is basically full-strength lye) and it can be made quieter with less flex (water leakage) than a plastic tub. (The entire pressure vessel and primary piping loop of naval nuclear reactors is cast or forged from DT304 stainless steel, although Naval Reactors uses a heavier gauge than KitchenAid.) The trick is to make it without galvanic corrosion from connectors, which is the most common source of "rust". It's expensive to do correctly.
Stainless dishwasher tubs are also recommended in Rex Cauldwell's "Plumbing a House", which is as close to the plumber's Bible as I've ever seen.
