Follow-up to my prior question about loud noise during wash cycle. To cover my bases, and because it was more cost effective overall, I ended up ordering an entire sump assembly (3485ED1002B) Due to the work revolved in dissasembling the unit to replace the entire sump assembly as a whole, I ended up removing all of the parts from the new sump assembly except for the heater element, and installing them in the existing sump housing. So the dishwasher has a new drain pump, wash motor, diverter motor w/switch and soil sensor. I used all of the cover pieces from the new sump assembly that you access from inside the dishwasher, as well as the grinding blade. The only parts of the original sump assembly are the base housing and heater assembly.
The noise during the wash cycle is now 50% quieter then it was before replacing these parts but it's still 50% louder then it was originally.
I know it's definitely wash motor noise, but I'm not sure if diverter motor noise could also be in play (not sure when the diverter motor runs)
My dishwasher was purchased in late 2006 so I know I now have revised parts. Are these newer parts louder than original parts? Is there something else that I have not replaced that could be causing the wash cycle noise to be louder than originally?
The diverter motor will be operate throughout the wash cycle and switches from upper to lower spray arms on the unit. It is very plausible that the diverter motor could be defective and need to replace.
