Melted plastic

This one's a story, folks. Jill ran the dishwasher yesterday, and it wasn't draining. She asked if I could help. We took out the dishes and I took apart the moving parts inside. They were loaded with gunk, which I cleaned out. I put them back in and ran it.

I hadn't noticed that I did not put the rotating sprayer or filter on properly. Jill said she smelled burning plastic. She turned off the dishwasher and opened it. The water was draining, but the sprayer and filter were melting on the heating element. They had big chunks melted out.

I went online and ordered replacements. Ouch. For now, dishes will be done by hand.
