My thought was that the intent of the panel was to have the DW blend in with the rest of the cabs and matching the hardware and locations helped further the illusion. But it depends on the look of your panel.

In my previous kitchen, I had what looked like a drawer on the top with what looked like a door on the bottom, both glued/screwed to very thin luan which was in turn attached to the DW. So I put the same drawer hardware on top (no problem opening DW) and the same door hardware on the bottom (nonfunctional but that's a different thread...).

I went with a larger appliance pull and I am glad I did. My door is VERY heavy. You may want to check the weight of the panel before you select the pull.

I have a regular 3" pull. It works perfectly. Keep in mind that no matter how long it is it is still held in with 2 screws. As long as it is comfortable in your hands you will be fine...

I have cup pulls on my drawers, but I went with a handle pull for the dishwasher and trash pull out. I don't think I could have fit a cup pull on the narrower top molding of the DW panel. I think it depends on your door style. Also, I used knobs on my top drawers because the raised panel of the top drawers did not have enough height to put the cup pull. I am happy with the final look and function.

Knobs and cup pulls:

I have no problem with the cup pull on my dw and trash pull out. I like that it matches the rest of the hardware.

same cup pulls for drawers and DW. 5 years old, no problems!
