My Maytag dishwasher has been leaving a lot of residue behind. I ran it with dishwasher cleaner a few times already, then i inspected the spray arms and they were clogged. I removed the lower sprayer and I think I cleaned it out but I can’t remove the upper arm and there are pieces of plastic in the holes. (like saran wrap or something) I have been trying to get the pieces out but can’t. I want to take the upper arm off and can’t figure out how…HELP!
