I have a Kitchenaid Superba dishwasher, and I can't find the manual.
It seems they don't offer manual PDF's on their website.

I was cleaning out the inside of the dishwasher because our dishes
have been coming out with lots of food particles on them.

I can see some large pieces of food down under the grating at the
bottom of the dishwasher. The spray arm is attached to the grating
cover.

Anyone know how to take this apart so I can clean out the bottom?
