Question about Gaggia Syncrony Compact Coffee Maker/Espresso Machine

1 Answer

My Gaggia Syncrony Compact has developed some sort of leak. Every few days I notice a pool of water spreading across the countertop in our pantry and pooled under the machine. The leak might be happening daily, but I don't notice it because of the clutter around the machine. My best guess is that the spring valve (or whatever you call the part that lets water be drawn from the clear plastic water tank in the back of the machine) seems to be leaking. I tried descaling the machine, hoping that some scale was preventing the water tank from forming a secure connection with the base of the machine, but to no avail. The leak continues. Any suggestions?

    I'm trying to methodically figure out where and when this thing leaks. I wanted to test whether it leaks while brewing, as bansherarcer suggested, but when I just warmed up the machine, it leaked a bunch of water. The vent area in the back of the machine has water running down it. Though the water could be coming from the vent area, I suppose, I should note that the little recessed areas just beneath the water tank are regularly full of water. Screws at the bottom of two recesses are even rusty. Do those symptoms help narrow down a probable cause? Thanks in advance for any suggestions.

    I have never noticed a leak from the front. (Sometimes a little water comes out if I accidentally knock the coffee dispenser after I've brewed a cup, but I don't think that's what you mean.) The only visible leak is from the vent area, plus I have found water pooled in the recesses in the machine's body just below the water tank. The leak always seems to happen after I have brewed a cup and turned off the machine. It seems to happen some minutes after shutdown, as I have never witnessed the leak until I checked the machine some time after brewing yesterday. And the leak is not consistent. Brewed a cup today and no leak. Go figure. Any thoughts? Thanks.

    I think that Bansheracer might have nailed this one with his first theory--that the leak was caused by an old washer (the one that sits under the plastic ring beneath the water tank). At first, I didn't think that could be right, because the washer seemed snug. But since it was my cheapest fix ($15), I ordered that part from and, now three days since installing it, I have had not even the hint of a leak. Thanks for the suggestion, Bansheracer! I really appreciate your taking the time to help me out!

    I think your first idea, that the seal was worn, was right. At first, I thought that couldn't be it. The seal seemed snug, but replacing it seemed like the simplest, cheapest option (15 bucks). So I went for it and after three days of operation, the machine still is NOT leaking. That is a lifetime for a machine that was making a daily habit of turning our counter into a pond. Thank you, Bansheracer, for sharing your time and expertise with a stranger! I really appreciate it!

    I purchased mine through Whole Latte Love. I ordered mine by calling their number. Not sure whether you will find the part on their web site. It cost me $15.51 for a simple 50¢ washer, but I figured it was far cheaper than buying a new machine. I might have been annoyed by the price, if the washer hadn't fixed my problem, but I've had no trouble with my Gaggia since making this simple repair. Best of luck.

I would suspect the seal on the machine where the tank sets on the machine. There is a plastic cap that looks like a doughnut, that will pry off (there are 2 hooks, 1 on each side). The seal is under neath. If you can stick your finger in the center of the seal and lift it out it needs to be replaced. When you put the new one in, run your finger nail around the outside edge of the seal to get it to slip in or you could damage the new seal.

    Thanks for the suggestion!
    I took a look at the seal and I could get it out, but it was sort of snug. Didn't just slide out with no effort. Not sure whether it needs replacing, but that would probably be a cheaper thing to try than replacing the water tank! Any suggestions where I might find a replacement seal?
    Thanks again for taking the time to post a reply.

    Water tanks don't leak if they are on the machine. You could have an internal leak if it happens during brewing.

  • bansheracer Oct 26, 2010

    I would say that the leak is internal. Its been a while since I worked on a Gaggia compact, but they are the sam inside as most of the rest of Saeco's machines. More than likley it is a tube going from the boiler or the seals on the tube depending when the machine was made. Does it leak in the front of the machine at all?

  • bansheracer Oct 26, 2010

    There is a panel behind the brew unit that comes off with 2 screw. This is where the pressure is diverted to the drip tray after brewing. It can become filled with coffee residue and overfill with water. Stick your finger in the little pocket and see if there is water? Or just pour some water in it and see if it drains into the drip tray?

    Hi, I seem to have the same problem, and thanks for all the advice. The same question too, though, where do I get the washer/seal?

Gaggia syncrony compact is leaking. Removed top and it appears it is leaking from the area that the line goes into the steam knob. Doesn't leak when using the steam knob, just when brew coffee

Hi What color is the steam manifold? It is located under the black cover with the trough in back under the whit tube. If its whit or black it probably needs to be replaced. If you cool down the manifold after steaming you can prevent this from happening. Just turn off the steam and then open the knob again to run water. It comes out steam at first but then will turn to a water stream. Then you can close the knob and go about brewing or just let it stand.
