Question about Gaggia Syncrony Compact Coffee Maker/Espresso Machine

1 Answer

No water comes out on ventilate. At first, the water was coming out very slowly, in drips. The doser or grind were not the problem, because even when I switched to Hot Water, it was still dripping. Although I had descaled the machine a couple of weeks ago, I decided to try descaling it again. I use the descaler sold by Descaling took just a few seconds, as well as the rinsing process, after which it asked me to ventilate. When I ventilated, It took it about 1 hour to empty the tank. I took the brew unit off, cleaned behind it, cleaned the hot water spout, cleaned the spot where water goes from the tank in the machine and after I put it back together and tried to ventilate, no water came out and after a few seconds it showed "Hot Water, Turn Knob". Once I turn the knob, it goes back to ventilate and the same thing happens every time I try to ventilate. Occasionaly, it spits out a few drops of water and for 1 second it looks like it starts to work, but right after that, the water stops. Please HELP! I have been taking good care of my 3 yr old Gaggia, rinsing weekly and descaling at least every 3 months.

It should take about 45 minutes to an hour to properly descale the machine. If it only took a couple of minutes you really didn't descale your machine. If you used the powder it has to disolve completly before descaling. The best way to descale is with the descaler in the tank. Turn on the machine and run about 8 ozs of water-descaler through the wand and then turn off the machine. Wait 10 minutes and repeatthe last procedure. Do this until the tank is empty. When done with the descaler, rinse out the tank and put fresh water in the tank and run the whole tank through the wand. Then fill the tank and your ready to go.

    I know. That's why I mentioned the fact descaling was so short. When I descale my machine I usually do it the way you described, alternating with making large coffee through the bypass with no coffee in it. I always make sure the water turns clear when I stir the descaler, before I pour it in the tank (which I remove in order to do that). The problem I have right now is that there is no water going through the system. I can get rid of the message by selecting Factory Settings on the menu. But if I try to make coffee or just run hot water, it cannot do it, therefore bringing the Ventilate message up on the screen. But the machine can't ventilate. It looks like it can't get water to pass through. I also noticed that there is a little bit of water leaking through the bottom of the tank where there is the spring mechanism that let's the water out once you put it on the machine. I don't know if it's normal. I just noticed that, after leaving the tank sitting on the countertop for a couple of hours. Is there a way I can take the enclosure out and look inside to see if maybe something is blocking the water passage? And should I do that?

    Never descale when the machine is that hot. The descaler will turn the silicone gaskets hard after a while and the machine will start to leak. Never descale through the brew unit also. It will weaken the stainless steel brew screen and it will crack. The best way to descale is through the steam wand with just water. Warm water is ok, just not hot. The programed machines that have the auto descale never turn on the boilers for that very reason.

  • Lumi Reed Nov 14, 2010

    What should I do now? How can I get the water to run through the system again?

  • bansheracer Nov 14, 2010

    Take the black panarrello of. Loosen the can on the panarrello all the way and the tip should come off and the cap should stay on the wand. Take a wire and stick it up the tip of the wand and see if anything is plugging the tip. When you descale sometimes calcium breaks of and plugs the tip of the wand.
    If it can brew its to hot for descaling. Remember, turn the machine on and run some water through the wand, then turn the machie off. Let it set. Then repeat until the tank is empty.

  • Lumi Reed Nov 14, 2010

    Nothing seemed to be blocking the wand. I had the machine turned off since yesterday and after I was done with the wand, I turned it on. As before, Ventilate was on the display. I turned the knob to run water, nothing came out and after a few seconds I had the message Hot Water, Close Knob. I closed the knob and Ventilate showed again. This time, when I turned the knob, not only no drop of water came out, but the machine started making a very loud noise. Any thoughts on what I can do next? Thank you.

  • bansheracer Nov 14, 2010

    Without having the machine in front of me its hard to say. If you have one of the new type J boilers they only have 1/4" tube that runs through them. It could plug up, because I have seen that before. If it is pluged up you will have to replace the boiler. Sorry

  • Lumi Reed Nov 14, 2010

    Can I take the machine apart to see if the boiler tube is plugged up? And if I do need to replace the boiler, is it worth it? I couldn't find any Gaggia repair outlets in the area (Kansas City, Missouri), which means I would have to send it somewhere. Could I replace the boiler myself?

  • tcnichols Nov 19, 2016

    when I descale my syncrony compact digital it only runs for about 30 seconds and stops - I've repeated several times but can't get it to go any longer. thoughts?

When the grinder spins free and fast it only means that fresh beans are not feeding into the burrs. This happens when:
1- Grind setting is too fine and beans cannot enter the grinder mechanism.
2- Use of oily dark roast beans can clog the ground coffee chamber and preven the fresh beans entering the grinder.
3- The ground coffee chamber outlet is clogged due to oily beans or too fine coffee setting.

When you cleaned the grinder you may not have cleaned the coffee outlet to the doser on the left. You can clean the outlet to open the passage of coffee grounds to collect in the dosing device..
After cleaning the outlet, you should next make sure that coffee grounds are not packed in the doser. The doser is inside the door right above the brew group.
To access the doser:
1- Remove water tank.
2- Remove the brew group.
3- Lay the machine on its back for full view of the doser.
4- Pull the doser door open (it is like an Attic door.
5- Keep the doser door open and clean the inside with a brush. The outlet from the grinder is on the right side with a wire wiper cleaner that moves across the grinder outlet fills from the grinder. This opening.
Use a brush to clean the doser.
On the left of the doser space there is a plastic flap that is pushed to the left when coffee grounds fill the doser.
At certain distance push back (1/4") the notch on top of the flap pushes the doser micro switch pin to stop the grinder. Push the flap gently to the left to make sure that it is moving well. With each push back of the flap, one can hear the feeble click sound from the micro switch.
When the above cleaning is done, try the grinding.
If the conical burrs have not been replaced for over 2500 grinds, it is time to do so.

The above grinder and grinder doser cleaning instructions are available as download files on the following page link:

One can find many useful maintenance guides on one page.
Good luck.

Our Saeco Vienna Superautomatica sounds like it's grinding beans but keeps running until the red 'bean' light comes on and we have to shut the machine off. Any suggestions?

The grinder is timing out and stops if the beans do not enter the grinder. This happens because:
1- The grinder outlet is clogged and fresh beans cannot pass through the burrs.
2- The grind setting is too fine and helping clogging in the grinding chamber or the ground coffee outlet.
3- Operator may have been using dark roast oily beans. Like it or not, the dark roast oily beans do not make stronger espresso. Please stop using such beans in fully automatic espresso machines.
4- The grinder has already made over 2000 grinds and the burrs are blunted and not grinding beans as needed.
To solve this malfunction, clean the grinder. Make sure the grinder outlet to the doser is cleaned. This outlet passage is about 2 inches or more. To clean it, lay the machine on its back (water tank side) to allow better view of cleaning the doser and the passage of coffee from the grinder to the doser. Use the link below to find instructions for cleaning the grinder and replace the burrs.

Put 2 spoons of coffee in the by pass dozer

The machine is made to grind WHOLE bean. Why are you trying
to bypass the grinder? The machine measures both bean grinder
and water with timing.

Have grinding noise in dash repeat over and over. sounds like CD trying to recycle but no CD inside and no cassette tape. it only comes on when ign switch on, no sound when key switch on access

I bet you have a leaf or leaves inside the heater blower compartment. The blower motor fan is always turning slowly even though the AC or fan is turned off to provide for ventilation. See if the grinding noise changes when you turn the AC fan on or off.

Bypass doser doesnt work. I put grinded coffee powder in there and hit the bypass button, then the small coffee button, The machine starts but no coffee dripped but only hot water? Did I do something...

Hi, sounds like your pushing the wrong button or doing the process in the wrong order. If your putting coffee in and only getting water, then that tells me that is is dumping the coffee before it gets brewed. dazza

  • it can be too tight stringed at burrs
  • some stone or metal part with coffee went between burs
  • IF IT IS AUTOMATIC, it can be one of 2 micro-switches or main relay, in this case you have power but only to middle of way.

  1. Release the burrs, grind one amount coffee with bigger granulation than go back again carefully.
  2. Disassemble the upper burr holder and clean carefully, all coffee and remains put in one plate, inspect with magnet, hand and than put all that in water. (heavy parts fell down fast in water)
  3. Check the switches and relay:
  • Upper micro-switch has an plate and one box where it is( box might be full of coffee or the plate blocked and giving the signal of full doser every time)
  • Lower micro-switch should activate every 6th pull of doser(he is below in mechanism of doser)
  • Relay gets power from micro-switches when they command. even we switch on if the commandsof micro-switch says off than relay will not obey us.

Krups grind & brew. It grinds but water

Check to see if your heating plate gets hot when it is on, if it doesn't your water heater/heating pklate has failed.
