Simple fix. I used the test codes which are on the paperwork attached to the dishwasher to identify the darin pump was not working. Just hummed like it was stuck. Took out the DW and opened the old pump to see if something was stuck in the impaellor. Nothing there. Turning the impeller by hand was difficult. Ordered the pump drain assy and paid standard shipping. SHowed up in 2-3 days. Put in the new pump and everything is good. Very simple remove and replace. Took less than 20 minutes once I had the new part.
I did not need the flapper valve because the pump assy had a new one in it.
Thanks for the great service
