My Quickmill Anita started blowing steam. Turns out it was the safety valve letting off pressure. Marcus guided me through determining the cause of the problem (a bad pressure stat) and how to get to it and replace it. I was a bit intimidated, but it turned out to be easy as 1-2-3. Great service! The part itself? Whoc cares -- it works again. 5 Stars for Marcus and Chris' Coffee!
