Hi I recently bought a second hand Gaggia classic and am experiencing a few problems. :(

I have read the manual and watched a few tutorials however when I go to run water through the group head / shower head, water only comes out of one of the holes and therefore more water pours through the one side which provies a unbalanced espresso taste. The water also spurts out the group head at a weird angle and goes all over the work surface and not in the water tray which is pretty annoying. Anyone know how to fix this? Would appreciate any help thanks a lot.

Yup! This machine has a classic case of SCALE Build up.

You can take apart the shower head with one ALLAN key but you should get yourself some ESPRESSO MACHINE cleaner
or powdered citric acid to mix with water and run through the boiler... SEVERAL times.

DO NOT USE Vinegar!

Usually 1 Tablespoon of powdered citric acid (It's food safe!) mixed with a litre of water is a good starting point.

GOOGLE: Cleaning your espresso machine - there are likely articles on this here website!

Here is a good article to start with.

Ok cool thanks colin so do you reckon I should take it apart using a allen key and clean it out and then buy some espresso cleaning chemicals and dilute it with like a litre of water and just run it through the whole machine? cheers.

You can just use an espresso cleaner liquid mixed with water into the reservoir before taking anything apart.

STEP 1: Clean by running liquid though the system first. A flush.

Hi guys, I returned that machine to the seller because he claimed it was new and clearly wasn't. so I bought another one which is newer. made in 2007. but i've still took your advice and descaled it with citric acid and backflushed it using espresso cleaner. it runs perfectly, although I am experiencing some difficulty forthing milk. I have upgraded the steam wand to the silvia v2 wand with a 3 point tip instead of the 1 hole tip on the original wand.

1. Although when I froth milk it just seems to draw in the bubbles from the surface and not incorporate any other part of the milk. Also find it hard to get more than the amount of froth used to create latte's (so find it hard pouring cappuccinos). The milk doesn't seem to incorporate well with itself. I am used to using a commerical machine as I work at Costa Coffee. I asked myself: May this be because the machine has only been turned on for 5 minutes and is not hot enough? So I left the machine turned on for about half an hour and then came back to froth some milk, this time the steam wand felt a bit more powerful and incorporated the milk a little better (allowing me to create a whirlpool when frothing). Does anyone have any suggestions on how long to leave the machine on for?

2. Another problem - I am not sure what the temperature of the water coming out the group head should be but I suspect that mine is not hot enough, does anybody know how to increase the temperature of it?

3. Also the manual tamper that comes with the gaggia classic does not fit in the whole of the filter basket when tamping so you kind of have to do a few diffferent tamps to get it right. Anyone have any recommendations on good tampers to buy?

I do apologize for the long list of problems I am experiencing however I am forever appreciative of your help and advice.

Thanks, Jon.
