Whirlpool Dishwasher repair. My wife says I have a couple of days to get this thing working :)
Dishwasher making noise in wash cycle. Checked for "junk" in the sump area while it was still installed. Removed a piece of glass but the noise is still there in wash cycle. Moved dishwasher to garage to determine what I can disassemble.
Found a great manual which closely matches my model.

My approach at the moment is to remove the motor and other parts to inspect for broken parts or junk. I'm on page 20 of the manual above. Instructions indicate removal of a bolt that holds the trip shield in place and apparently also serves to lock the motor in place and prevent it from twisting (which is a step in motor removal). My problem is that although I can see the head of the bolt, I cannot get to it.

Here are the instructions:
1. Remove the bolt securing the wash motor and drip shield in place on the pump assembly. (Fig. 3-18)
2. Once the bolt and drip shield are removed, turn the wash motor until it stops (approximately ¼ turn).
3. Pull the motor straight back from the sump assembly. Some effort may be necessary to dislodge the motor. The volute will remain attached to the motor.

Has anyone done this? Tips?
Thanks, Ed
