any website I could possibly use to find Id appreciate.
I believe the Caffe Trieste is the Model BCO80 machine from DeLonghi. If that’s the case, here’s a direct link to the user manual:
If your machine is not the BCO80, you can go to the DeLonghi website at http://www.delonghi.com . Select the customer service tab on the top of the page, then on the left hand side, click on the "Instruction Manuals" link. That should get you on the path to finding your user’s manual.
