I have a Gaggia Coffee Deluxe that I bought on Craigslist a while back. The flow was very low, so I descaled it. At some point during the descaling process, the flow stopped almost completely. Steam works fine. When I try to pull a shot, it makes a very faint sound and there is little to no suction.
I took the group head and boiler apart and cleaned them, that didn't help. I suspect the culprit may be the pump. It's an Invensys CP3A (see picture). At this point I could use some help:
- How do I make sure the pump is the problem? - Is it possible to take apart this pump and/or clean it? - If it's broken, what can I replace it with?
Hello. A member of the Yahoo Gaggia group saw this thread and thinks the hole under your group head is plugged. Head over to http://groups.yahoo.com/group/Gaggia/ , join, post your question and they'll help you out. The pump should be ok.
