How to replace broken steam valve? Water only comes out of steam wand
We recently moved and our Starbucks Barista (SIN006) got jostled and the plastic 'mushroom' knob for the steam valve broke off. I can use a pliers to turn the knob but even when fully clockwise, hot water (but not steam) shoots out of the steam wand. I took the top off and I do not see any obvious damage. The little contact switch seems in good shape (I figure that must control whether water goes to the brew head or the steam wand, no?)
1. Am I right to assume that the problem -is- the steam valve assembly?
2. I loosened the nut that seems to secure the steam valve assembly to the brew head, but the steam valve assembly does not want to slide off. How do I remove it? Do I just need to force it or is there some other thing holding it in place?
Thanks in advance!
Is this a good question?
