Using our dishwasher's model number, I did a search on the AppliancePartsPros.com website and found the part with no problem (yay!). Discovered the 'How to video' on the same page as the part I was purchasing and watched it before the replacement part came.
I am a 75 year old woman. I replaced the broken part in no time with no problem following the 'how to video'. Thank you!.
