Gaggia Classic, weak pump? (solved)

by admin on October 6, 2010

Yesterday my Gaggia Classic began to sound different as I made my espresso shots. The sound you hear uccurs when the espresso is made ristretto style, meaning the pump gets to work a little bit harder, but coffee normally begins to pour within 5 seconds.

This happened to my one after a descale and back-flush and I thought I’d burnt out the pump. I was getting ready to send it for a service and suddenly it started going strong again! Pretty relieved – hope it lasts…

If you read the comments, you can see that the problem is fixed, and how it was made OK again.

hmm in case it’s still not working properly, I recently had that problem. I just let the machine run for abt an hour. Obviously I refilled water in between but that seemed to have fixed the problem.

The problem started just after a descale. However, after I remade the process a few times it went back to normal.

The newer machines are equied with a weak pump, the older ones are much much better.

This happened on my extra starbux barista machine, keep priming the machine and it should stop after the 9-10th priming

Would you care to comment on my video (user hshortt) as it appears even worse on the newer Gaggia machines Thanks a lot.

Thanks for your reply. The stranges thing just happened to me a few days ago. The pump started to sound strong again, even though I choked it with blind-filter.

Hope it continues to live :)

I have the same machine and I can choke it without the pump giving up or pulsing.
Think you should have the pump checked out.

I’m puzzled as well. The machine itself is quite new. It begun when the machine was about 8 months old or something. I’m not sure I follow what you mean about the grinder. The pump sounds that wiered when I make espresso ristretto style, not when I make ordinary espresso. I’ve had no problems before doing ristretto.

I’m puzzled by the pulsating sound from the pump. The extraction looks like it’s happening consistantly, though. Is this new or has the machine been like this before the grinder?

This has nothing to do with the grinder. The Minimoka M203 is quite new.

Ofcourse the pump will not need to work as hard if the grind is sett coarser, but you can’t get rid of the fact that the pump really should be able to manage that fine grind I’m using in the video.

Seems to me that you should check your grind. If you can’t fix the problem with that adjustment, then it may be time for a new burr set.
