Product review (5 stars): Simple to install
Like a lot of others, the door latch on my Maytag dishwasher broke, and I ordered this to repair it.  It was very simple to install on my model: First, unplug the dishwasher or turn off the power from your breaker box -- there are live connections to this part, and you'll give yourself a nasty shock otherwise.

Then, open the dishwasher door and remove the ten or so screws along the inside edge, so you can lift up the inside panel from the door frame.  The old latch piece was attached with two of those screws, at least on my model, so after removing them you should be able to just take it right out.

The only tricky part I ran into was disconnecting the wires from the old assembly; they were wedged in tight and I eventually had to use a pair of pliers to pull them loose.  I was worried I might break something, but I was able to get them loose with some firm pressure and wiggling.  Then, just plug those wires into the same part on the new assembly, put it back where it belongs, and screw the door panel back on.

It might just be wishful thinking, but the new latch looks stronger than the original one.  Here's hoping!

I think the people saying that they received a knockoff or that their part was missing the white handle (or only had the white handle) must've received the wrong part by accident.  The part I received had both the white handle and the rest of the assembly.  It was all I needed to fix my broken latch.
