I have a lot of steam escaping from the triangular flange that connects the grouphead to the boiler. I'm *assuming* there's a gasket in there, but I don't know how to order it. I already bought the wrong part from Espresso Parts based on a guess. Maybe there's an exploded view somewhere with the part number or name?

I think that it is this one: https://www.espressocare.com/products/i ... er-thicker

Parts diagrams, etc., can also be found at espressocare.com

Perfect. Thanks.
