Began by looking for parts on the internet. With in minutes I found and opened the appliancepartspros.com website. I entered my diswasher's brand name and model number and was pleasantly surprised that the parts needed were all available. Totally unexpected were the "how to" Utube videos showing how to remove the old parts and install the new ones. Watched the video's and ordered the necessary parts confident that I could install them.
The parts arrived much sooner than I anticipated (must have been shipped that same day they were ordered)?
As instructed, I turned off the water supply, and unplugged from the electrical supply, and began the intallation per the videos. In less that forty five minutes had completed the installion!
