Never had an issue with this DW in the past. 4 weeks ago it went dead, did the research and replaced the thermal fuse and associated wiring harness. Used a volt meter to confirm fuse was indeed blown and shorting across the fuse terminals energized the DW. So replaced and all was good until two weeks ago, same situation...no power and fuse was open just like first time.

I researched forums and found two possible issues....1) not replacing the entire wire harness (I did replace the entire harness) and 2) loose spade connectors to the heating element that drew excess current causing wires/connectors to melt. Well I looked over the entire harness and found 1) no loose spade type connectors and no evidence of over heating wires.

When the fuse blows about an inch of water is left in the bottom of the DW.

There was mention of running a diagnostic cycle for the DW....I can't find any details on HOW to do this.

What are the next steps suggestions to run down causes to this fuse to keep blowing? Thanks!!
