I found the button to push for "Test Mode" (Press and hold “Select Cycle” and “Heated Dry” for 3 seconds). When I got it in test mode I heard a clunk like something was reset. It went through a cycle with water and it drained and dried the dishes but the motor noise was really loud. I took off the kick panel and the noise is either coming from the motor or perhaps the pump (impellers) behind the motor. I would guess the pump because motors either work or don't work and before a motor goes back they usually have some electrical smell to them...I could be wrong but I have a place to start looking.
I still like to know what this piece of rubber stuff that has fallen down on the floor underneath the dishwasher. Maybe some type of sound proofing insulation?
