Environmental issues for the Junior: Since the single group M20/1 Junior are a residential espresso machine, It's usually in a kitchen, Galley, or restaurant. High heat, cooking oils, and liquids (syrup, soup, coffee, milk, etc.). Many smaller items are left on top of the machine's cup rack. I have overhauled machines that had caked syrups, Liquid sugar, milk, chocolate, etc. covering all internal parts of the Junior. Lots of small parts; small stirring spoons, rock candy stirrers, toothpicks, paper clips (notes), old post cards (last sales items). I've mentioned the typical life span for a junior is 3-5 years. Abused machines less than 2. During the time of any serious repair, a review report is offered to the owner, though in most cases it's a choice of a serious overhaul or a new (upgrade to a 2 group) unit which is a better choice as a restaurant should be improved after 3-5 years of operation. Most overhauls are done by Factory representatives working in a locality and performing it for rental customers.

Is that espresso machine corroded because it was keep near a place blowing with sea breeze?
