Hi, all,

I've just bought a Gaggia Classic and noticed that when I'm making espresso (i.e. have the Brew Switch turned on and water running through the filter basket) after a few seconds there is a water drip forming in one spot on the outside of the Brewing Head.

It's only a few drops of water falling during a 25 second extraction, and I can position the espresso cup to avoid it, but I'm wondering if this is going to get worse and if I should return the Gaggia for a replacement unit.

I bought from Amazon and have a 30-day return policy.

Less importantly I also note that the drip tray doesn't sit flush with the Gaggia metal frame. It wobbles a little if I rock it, even when I ensure the two little feet on the bottom are slotted into the metal frame. Not a huge deal, but I wondered if all Gaggia's are like this or if the plastic on this one is a little warped.

Any help in deciding whether to have this unit replaced would be appreciated.

best,
Jake

On the tray, dont slide it all the way back, there is spot where it sits about 1/8 of an inch off the water container. Is the drip coming off the portafilter, or from the overflow in the back left corner?

Thanks for the reply, steamer.

Re the tray, even with the tray moved a little forward from the water container, it's still not sitting flush. It can be rocked a little. I wonder if that's normal or if the plastic is warped a little.

Re the water drip, as I look at the circular brewing head while brewing, a drop of water appears on the rim of the brewing head, then drops. It seems like it must be a slight seep from the portafilter. Should I be seeing this on a brand new machine and is it going to become a worse problem?

Welcome to the forums and congrats on the new machine!  

The tray sounds normal.  My GC also has a tray that does the same.  As long as the feet on the bottom of the tray are sitting in the metal slots on the machine's body, you're good.  I can wobble mine pretty easily.  If you're saying the tray somehow slides out from the body of the machine unintentionally, there could be a problem.

I have a relatively new GC and I've never had the dripping from the group head as you described.  With excessive pressure or a old and dried out grouphead gasket (makes the seal with the rim of your portafilter basket, and sits inside the grouphead) water can drip, but you'll see it run down the side of your PF.  It sounds like your dripping is coming from the superior portion of the group, where it is bolted to the machine's body.  If you told me you bought this machine second hand I would ask about the gaskets, descaling history, pressure adjustment etc etc but you have a new machine.  I hate buying something new and not getting it in the proper condition.  I would 100% just send it back to Amazon and get yourself a new one...let them deal with Gaggia.  I've returned multiple things to Amazon and they've always made it easy so I doubt you'll encounter problems.  I would also be worried about opening up my new machine to try to make an unnecessary repair, only to somehow void the warrantee through Gaggia.

Thanks for the welcome, Whit.

All I know for sure is that the drip appears on the lip of the brewing head, always in the same position, and seems to come from inside the group head, rolls out, then drops.

Yes, sounds like I should just send it back for a replacement.

By the way, before sending it back, how do I empty the boiler?

We never want to run the pump dry because of the potential damage.  However, when you got the machine you had to fill it up with water and turn it on to get water in there in the first place so a few seconds of dry won't hurt it.  Just empty water out of your tank and hit the brew switch with no PF locked in place.  Flip the brew switch back to off as soon as the boiler is emptied.  If something bad was to happen...well you're sending it back anyhow.  Regardless, good thinking.  I love my GC and I'm sorry it sounds like you got a lemon; I'm sure you'll be happier when it gets solved.

Great! Thanks for all the advice, Whit.

I'm sure I'll be back on here when I get my replacement.

I do not think that will empty the boiler.  If you look below, the "up tube" in the boiler takes water off of the top.  If the level drops below the tube, no water out but almost a full boiler.

I was under the impression that newer Gaggia machines had another hole in the lower portion of the boiler out-tube.  I heard they started making them with that to avoid some of the temp problems of just sucking water out of the superior portion of the boiler.  The diagram doesn't really show anything there but its more of a parts replacement diagram than for functional description.  Either way I don't think you can go wrong by following the second link posted.  D4F knows a think or 2 about temp control on Gaggia so I would defer to his instructions.

Just to update: I watched very closely as I was brewing today and I can now confirm that the water is coming from the outer edge of the brewing head so I'm definitely sending it back for a replacement.

Thanks again for your help.
