Happy New Year, plumbers!

We've had our "new" Whirlpool dishwasher (Model GU3600XTSB1) for 2 years. Our old dishwasher required cleaning of filters and disposal blades from time-to-time.

I'd like to check the condition of those parts in our new dishwasher, but have been having trouble finding a service manual for it.

Any ideas on where to look? I already have the User's Manual, Installation Instructions, and a Parts List from the Whirlpool web-site in-hand.

I can probably dismantle it from the Parts List, but it would be great to know what kinds of service are even possible, before I start taking it apart.

Looking forward to your replies, as always,
