Question about Gaggia Classic Espresso Machine

No water coming through brewing head

I bought my Classic off a reliable source. Hardly used. But whilst I can hear the pump working and the steamer works and there's no airlock, not one drop of water comes through the brewing head I've tried everything and it's driving me nuts!I've washed the shower head, prepared the machine over and over, done everything. Any ideas?? I thought these machines were virtually indestructible?

Hi there, I had a very similar problem with my Gaggia Classic. Worked fantastic every day for two years then one day the brew head was reduced to a very slow drip. I rang some Gaggia service agents and they all said it needs a service ($100-$150). The last one I called told me to descale it before bringing it in for a service as it was probably scale buildup. I told them it wasn't a gradual thing - it just suddenly stopped and they said what happens is the scale builds up to a point where a piece breaks off and clogs the pipeworks leading to the brewing head. So, I used the instructions outlined here: At then end of the second flush through the steam head, I closed the steam vale to try and push the descaling solution back through the brew head (just dripped through again) then left it for 10 minutes again. Did the same the third time and it went to drip again for about five seconds then bingo - burst back to full flow. Hope this helps.

CLR is a de-scaler that works great on these plugged up machines.

Make sure you remove the round screen that is held by a center placed, phillips head screw. You will need a very short, medium sized Phillips screw driver. Don't ruin this screw. If you have to go to to the hardware store and buy one to fit, go buy one that fits.

Turn the machine upside down so you and get your body weight on that screw to keep from stripping the head. I found that using Acetone and a small wire brush really cleans the coffee "goo" from this screen and the casting above it.

Leave the screen out until your machine is de-scaled.

You can get CLR at any hardware store. Mix it 50/50 with water for really clogged machines. Heat the machine up and pump the CLR mix until at least a little gets through the brew head. Make steam and get it out of the wand, move the CLR through the machine.

Let it sit over night.

It is helpful to put a lot of steam on the machine, then turn off the steam switch and turn on the hot water pump. Steam will shoot out like crazy when the CLR works through the brew head.

Strain the CLR you catch from the brew head and steam wand through and old towel and re-use it. Look for Chunks of scale. When no more chunks come out, you are ready to rinse. Use water two or three times to get the CLR out.

Enjoy your espresso.

Check the magnetic valve, this can be clogged by calc, cleaning doesn't help a lot. Replace magnetic valve, costs about 40 euro.
please check for parts, great site and great shop.

I had the same problem - and because no water at all was getting through the "brew head", running it with descaler (as it recommends in the manual) didn't work.  Worse, when I tried to get the crud out of the "shower head" bit as gaggia recommend in, I could undo the screw to remove the perforated bit, but when I removed the 2 allen screws to get at the rest of it, nothing happened.  Couldn't shift it at all.Eventual solution was to unplug it, turn it upside down (take out the water tank first!) and fill the whole area with lemon juice (it's stronger than commercial de-scaler, but filter the bits out first) and leave the whole thing overnight.  That cleared the scale out enough to allow the Gaggia-recommended de-scaling procedure to work, and the machine now works fine.  (Still can't get the shower head carrier out, though) Hope it works for you......

I know this sounds obvious but the "steam" switch (the middle one of the three) should be in the UP position i.e. turned off when you wish to brew. To use the steam this same switch should be in the down (ON) position. Sequence is as follows: Turn switch one to on position. After heating, switch three will light. Now turn switch three on to brew coffee. Off when brewing finished. Turn on switch two leaving switch three in off position. When switch three lights up turn knob to use the steam.

First, if water comes out of the wand while you are brewing coffee then the valve has a problem, it might need to be replaced or the pressure buildup is forcing water through.

Water wont flow past brew head

Hi there, it sounds like your boiler may be full of scale. There is a copper tube which runs from the group up inside the boiler which can get clogged up quite easily. When you take the group apart you will see that when you remove the shower plate and unscrew the bolt in the middle the safety valve and spring will pop out and then if you get a pipe cleaner or something similar and ram it up through the copper pipe. If this does not work then you may have to dimantle the boiler and give it a good clean out. Also although you say the pump is primed it could still be broken. All these problems usually come from scale though. If you get some descaler and try to feed into the boiler by pumping or running water out the steam wand this may free it up.

Can't Prime Water Circuit

Hi You need to switch Steam ON so it heats up and then turn Steam button OFF (no light) and then turn steamer knob counter clockwise you will hear the pump start up and then water will stream out. This is when it's primed. Turn steamer clock wise to close. You must do this everytime you use the steamer.

Gaggia Classic Espresso Machine - will not pump water

Hi, this is so easy to fix. Firtsly unplug the machine. Then remove the two screws in the top plate so that you can have access to the internals of the machine. You will see the red pump to the left hand side at the back. Remove the two screws that hold the pump in place (use a magnetic screwdriver so that you can pull the screws out). Pull the pump up towards you and then unscrew the thin plastic pipe at the top of the pump . It is the pump that has the scale build up problem. If you the put the water tubes into the water tank and hold a cup to the top of the pump to catch the water you then have to switch the pump on. You will then start to see lots of scale come out of it and the pump will pump more water than you are expecting so be careful. Be sure to cover the internals of the machine whilst you are doing this as you don't want to get water on the electrics and electricute yourself!!! Then rebuild it! Just svaed yourself £100 in having it serviced :-)
