One of the steam wands on my old 2 Gp Brasilia Portofino commercial espresso machine is no longer functioning. Mine is the version with the ceramic discs. Here is a link on sponsor Coffee Parts Web page https://www.coffeeparts.com.au/brasi...t-water-valves.
When you open the valve the steam comes out of the end of of what is described as a Pin part No 400107 rather than out of the wand. What I believe may have happened is that the steam tip got clogged and when the valve was opened in the past so sort of pressure relief part inside this part No 400107 gave way. I found what looks like it may be this pressure relief part inside the machine when I inspected. Coffee parts have Pin part No 400107 available for sale at a reasonable price.
Have 2 questions to help me repair this.
1. Do the plastic knobs just slide off with a bit of help. I would not like to break it by forcing it off.
2. Can I repair part 400107 or should I just order a replacement?
