Toggles...
I have that same Maytag design, and no way would it clean as well as yours. Those standing Pyrex casseroles and baking pan would have to lean in my machine. I have a similar cutting board, loaded just as yours, that emerged with tomato seeds stuck to the top. I use Heavy Wash with Hi-Temp option and Heated Dry, trying all brands of detergents.
I now have yibbles adhering to the door where it meets the right-hand side of the upper rack. And a sludge residue accumulates under the door as well. All dishes are scraped, and run daily. I check to ensure there is plenty of hot water in the tub, and both arms move freely.
The Maytag is about 3 years old. It replaced a Kitchen-Aid that was also 3 years old when the pump failed. This Maytag in no way compares with the far-superior tower-design Maytag I had in another house about 8 years ago. I think the next machine will be a BOL with a knob, and i'll just wash the dishes before loading like my Mother did.
