My older model had cheap plastic type rivets around the window. Of course they broke and water leaked out the window. I took the door apart and put in a new gasket the siliconed the heck out of it!
Put dishwasher on a counter or floor and put a nice thick phonebook under neath the opened door for support. Carefully replace window with gasket and a bead of silicone. Put enough weight on top to press it down and seal it. Leave for 24-48 hrs. I've replaced the window 3 times and this fix has lasted 2 years now. total cost about $10 and a little effort. make sure you use heat tolerant silicone.

If you don't mind rigging it. I took the door apart, drilled out the little plastic stand-offs on the clear plastic window, and put some cabinet knob screws with flat rubber washers all the way around the window. I took the door apart and basically replaced the plastic standoffs around the window with the knob screws. Once I tightened them all down (kind of a pain in the ****, I think there were about 20+ screws and nuts) with the gasket on the window in place, there were no leaks. I also put some silicone caulk around the outside of the window (for good measure). It looks kind of rigged, but it worked and it only cost me about $10.00 in materials and about 2 hours in time. I'm not sure how long it will last, but it looks pretty sturdy (almost sturdier than it did new).
