After having my wife complain for several weeks I "MacGyvered" a piece of copper wire to fix it. Months of ongoing complaining later and upon the threat that she was going to hire someone, I found the part on Appliancepartspros.com. It took longer to order than it did to repair. The broken part was the "left" one but I ordered the "right" side at the same time since they were cheap and figured the other would break at some point also.
Popped the old one out looking at the one that was working, and put the new one on. Works great. I wish I'd done it months sooner and not been yelled at for how long it was taking (not that my wire repair didn't actually work pretty well).
One upside to the quarantine situation then is that I got the dishwasher fixed.
