I was paranoid about trying to fix it myself. Thankfully my son-in-law said he would help. He got on his computer and found AppliancePartsPros.com. He emailed me the web site and after watching the repair video I ordered the parts. It did look fairly straightforward.
This morning I set up my IPad with the repair video and proceeded to do the unthinkable. I fixed our dishwasher in about 20 minutes following the step-by step instructions! As my son-in-law said it was easy peasy.
