What's the Brand???
OK, I reviewed my home recorded DVD of the scene...
Here are the characteristics I could discern about the dishwasher:
It has a stainless interior.
It has what looks like a pop out control knob on the right side of the control panel.
Center recessed latch.
White plastic exterior.
The white plastic door exterior has what looks to be a sculpted look, with a big bulge in the middle. I seem to vaguely recall seeing a dishwasher like that at Home Depot about five or more years ago, but can't remember the brand or model. Maybe GE, but I don't find anything like it on-line.
The bulge in the door panel leaves hidden gaps between it and the control panel, which might serve as steam release vents.
The racks look off-white, maybe light grey.
The actual scene has some incongruities: The dishwasher door is origninally partly closed, in the up position, like it was opened slightly to air out. During the scuffle, the door is knocked open and the lower rack mysteriously rolls out onto the door. Never seen that happen with a real dishwasher except maybe in an a major earthquake

... The control knob on the right side of the control panel initially appears to be nearly flush with the panel, but as the door drops the view from the side shows that it's sticking out about an inch. Might be one of those child proof pop-out knobs.
Of course there's also been some commentary as to the stupidity of loading sharp chef's knives pointy side up in a dishwasher, as well as the inadvisability of putting a good knife in the dishwasher in the first place. A good knife should be hand washed - the hot water and harsh detergents of a dishwasher will dull the edge as well as potentially warp the handles so that debris and stuff will collect between the tang and the handle in future.
Others think that Sayid planned the whole thing so he purposefully loaded the DW with sharp knives pointed up.
One thing is for certain: the dishwasher isn't a Frigidaire, because that door would have broken off its hinges when the assailant hit it!
