I Googled this error and saw this error a lot. Finally took the chance to order this part and see if I could fix it myself - someone who has never worked on appliances or done home repairs prior to this year. One of the sites had 10 simple steps to replace the part, but said it was a 1-2 hour job - thinking this would mean 4-5 for me. 30 minutes and done. Ran the dishwasher last night like a charm. It is sad that a 2 year old Samsung dishwasher needs replacement parts already, but happy to say that I fixed it myself.
