    Exactly same symptoms. Have taken to pieces and confirmed the pump is absolutely fine. The sound only changes when the boiler has been filled up, and water then won't exit through the bottom of the boiler. I guess I'll try the vinegar trick but it is definitely the bottom assembly that is blocked. The water entry (from the pump) into this assemble is fine too (tested that)... Is it possible to buy a replacement bottom section to the boiler, or best to keep trying to de-scale?

    My Gaggia was in storage for approximately 4 months. When I took it out, I found that the water flow was fine through the steamer but not through the brewer. I've taken the filter section and the screens off and cleaned them. I've waited 24 hours with the cleaning/descaling solution to try to get the pump clean. I only get a slow drip through the center hole of the actual coffee brewer. It was working fine before storage. Any other suggestions? I can hear the pump and don't want to break it.

    Hi. I have a Gaggia Evolution which I have always kept clean and descaled as I live in an area with very hard water. I switched on my Gaggia for the morning espresso today and it started making strange sounds. I noticed that bubbles were coming out of one of the tubes in the water holder and it was heating up and eventually boiling the water in the holder! I have primed it, water flows from the steam head ok but wont flow through the brew head. The pump sounds fine when turned on as normal.

    Any ideas please?

    Many thanks,

The most likely reason for poor flow through the brewhead is a blockage in the outlet valve.the outlet valve is behind the shower disc holding plate and can be removed with 13mm socket. a straightened paper clip needs to be insrted in the outlet to clear any internal blockage,then pump water through. if the outlet valve splits in two ensure the rubber bung is inserted upwards.once refitted all should be fine

    I've got a Cubika model and clearing out the scale using a paperclip is spot on. The outlet valve comes apart so you can do this, just be careful when tightening back up that you don't snap off the end like I did! To buy a replacement outlet valve will set you back 18 quid delivered (from eBay)

Sounds like the water line or pump is plugged or clogged. The line to the pump may also be clogged and that is sometimes harder to clean. In some locations the water supply has a heavy mineral content in it and "scale" builds up inside. Usually you'll be able to see this as white flaky material around the spiggot or look inside the tank. If you see this try this old home remedy. Fill the maker with 50% "white vinegar" and 50% Water and make sure you run some thru the whole maker if you can. (you can actually use 100% white vinegar if you want.) White vinegar is nothing more than "natural" acetic acid. It will dissolve the "scale". Works great on other things too. But takes awhile to work. Leave it in overnight but don't heat it. If that doesn't clear it up the first time, heat it up to warm but don't boil it or your coffee will never taste the same. Allow it to stay warm for several hours if you can. Then rinse with cold water several times. If all this doesn't solve the problem then you'll need to take to a repair shop and most likely replace the pump.

    it will be scale in the outlet valve causing this....quick and easy way to sort is to remove the filter (one screw), then undo the outlet valve with a 13mm socket. Undo the two parts (don't lose the spring), then use a paperclip to open up the hole again by removing the scale build up. Reassemble, but be careful not to over tighten the valve. This always sorts the problem and avoids tainting your coffee flavour with chemicals or vinagar.

I just had my Evolution apart down nearly to the last threaded anything for this problem. It was a stuck steam check valve (called a boiler valve in the drawings). A small piece of scale had wedged it's way in there last time I used the wand (which is almost never) and it wouldn't allow the water to flow through. A simple dismantle and clean was all it needed, I took the opportunity to clean the boiler chamber, screen, screen holding plate and group body as well. It's amazing how much coffee finds it's way up into that stuff if you really fill the portafilter full. I even took the pump out and blew compressed air through it to dislodge any bits of calcium that may have formed.

One thing I hadn't done in the past was run the pump with the portafilter off so really didn't know how much flow to expect. Once it was clean and back together, with the screen removed I get 4 pretty steady streams out of the plate holes. It will fill a 100ml beaker in around 30 seconds.

It works better than new now but I think that's probably because I've learned the method I like best to make a couple shots. It was informative, I now completely understand the workings of the entire machine and it's pretty dirt simple, guess I'll keep using it even though it's reputation isn't the best.....

Coffee coming one side only of spout

There are two ways to overcome this uneven drip of coffee into the cup.
1- Make sure the machine is placed on a level counter top. The coffee drips as a gravity flow. Machine placed on a tilted surface will allow coffee flow more on the tilted side.
2- It appears the coffee faucet outlet has not been cleaned/flushed with any coffee cleaners or descaling solution. Clean the coffee outlet as following:
* Prepare two or four cups of Baking soda solution.Fill the Baking soda in water tank and make few espresso, using the preground cycle.
** Then use two to 4 cups of descaling solution and repeat the process making several espresso.

Low flow, pump starts normal and within a few second becomes quiete

Hi There,
Try descaling - sounds like the the solenoid is blocked with lime - don't use vinegar! Try that 1st.
If machine is more that 2 years - not regularly descaled or no water filter replaced regularly, it probably the solenoid.
It the machines is 4 years + replacing both would be a good idea. Gaggia classic solenoid Vibration pump Gaggia Rancillio

I have a gaggia delux and the water never heats up.

There is a reset button inside on the left side of the boiler. You may have a burnt out element. you could have a fuse that is burnt out also. The fuse is on top of the boiler inside the plastic covered wire.

Hi, Our Gaggia machine will not disburse water through coffee dispenser. Sounds like its operating normally till water flow should happen. Then the motor slows down to nothing. Have descaled to no effect....

Try this press the button for ground coffee then when it lights up press the coffee brew button, if water flows normally then the grind on the grinder needs to be adjusted coarser, if no water then the screen on the brew unit is blocked.

Low water light stays on

If water light and heating lights go on and off, Try this: Fill water, turn water nozzle on, let water flow out. Water light should go off. Shut off water.
If coffee lights are solid, turn off the machine, let it cool off and try the above again.
