Tip & How-To about Gaggia Syncrony Logic 74884 Espresso Machine & Coffee Maker

Problem: No water flow; Solution: Unclog a small orifice in the flow meter

My 5 year-old Syncrony Logic stopped working for the first time today. The water would not flow, not through the steamer, not through the brew group. I had previously thoroughly cleaned the brew group screens, steamer wand, water dispenser filter, etc. Still no water flow. I could hear the pump working but no flow.

I only use distilled water in the unit, so I've never had a scale problem (distilled water has no minerals, thus nothing to create scale). After downloading a parts schematic from here, I dug into the case. By the way, I suggest you don't proceed unless you have at least some mechanical ability and are not afraid to break something in the process. Be sure to unplug from the wall first, unless you really like electricity A LOT.

After removing the drip tray, grinds bin, water tub, and coffee hopper, I removed the gray top. To do this: from the top remove 2 screws under the water tub, 2 screw under the coffee hopper. And from below the control panel: 4 screws from the under-side along the front and behind the brew group cover. Once the screws are out lift the cover at the back and pivot off the front.

2 things are attached to this cover: the power switch and water hose. The power switch easily slides off the top cover. The water hose runs from the water dispenser fitting and into a little white gizmo with another hose running out of it and into the pump. The little gizmo is a flow meter that ensures water is flowing. Remove the hose from the tank and flow meter in order to clean it.

The top of this flow meter easily comes off by slightly twisting the top counter-clockwise about 10 degrees, lining up 3 tabs with slots and lifting it off. Its a little snug coming off due to an o-ring seal. You'll see the little turbine wheel inside. In the top is the input and output ports in the flow meter turbine chamber.

The input opening into the flow meter turbine is TINY. It was clogged with a bit of gooey fluff. I poked it out with a small pipe-cleaner, then made sure the hose from the tank was clean, and the opening into the turbine was gunk-free.

After I put it all back together it ran like a champ again. I love this espresso maker. First problem in 5 years of flawless operation.

Coffee machine is displaying error message "BREWUNIT BLOCKED". Have tried opening up the machine to clean it out but nothing seems to be opening or closing properly!!

Remove the brew unit and clean the shower screen under the red o-ring, There is also a tube leading from the top of that o-ring to the discharge and is attached with 2 screws, remove screws slowly DO NOT LOOSE THE SPRING AND BALL that is under the fitting, clean out tube and the hole that leads to the screen, that should clear up the problem.

error message: 'brewunit is blocked' and i cannot get the brewunit out of the machine to look at it. it is stuck pretty hard. dont want to break it...any suggestions?

Your showing a Syncrony but this is for a Syncrony Compact. They are different.
Open the door. Remove the drip tray, dredge drawer. On the left side and towards the back of the brew group, there is a single screw in the brew group. If you can't get the dredge drawer out, just move it as far to the left as you can to get to the screw. Remove the screw. Grab the handle, squeeze and pull carefully, but firmly fast. Everything will come out (drip tray, dredge drawer, brew group and there might be water in the drip tray). The brew group should come out. There is a piece that remains in the machine. Slide the piece down and to the right and it will come off. Insert the piece into the hole on the backside of the brew group with the clip up. Tighten the screw and move brew group back into position.
To return the brew group to the centered position, you first need to drop the funnel. To do this, look on the opposite side of the brew group from the handle. At the top you will see an object that looks like a sharks fin. If you follow this piece down you will see 2 horizontal bars on the brew group body. Push your finger between these 2 bars and the funnel will drop. Now you can push the puck slide on the left side down and then to the center of the brew group. If you look down through the funnel you should see a piston. This should be centered in the funnel. If not just push the slide to the right until it does. Push the press button and you are now ready to reinsert the brew group into the machine. First you must insert the dredge drawer back into the machine. Close the door and turn on the machine without having the brew group in. You will hear the motor turn on and when it stops completely, pull out the dredge drawer, drip tray, then open the door and insert the brew group. Slide the drip tray,dredge drawer back in, close the door and test.

We have a Gaggia Syncrony Logic that is just over two years old. After each brew cycle, the puck is successfully ejected but water and some grounds flow out under the drip tray instead of into it. Additionally, the steam wand has stopped working (no water/air passes through it). Beyond these two problems, the grind and brew cycles work just fine. Any ideas?

Check the drain behind the brew unit. There is a pocket below the injector that can plug up and cause water to drain under the drip tray. Check this first. Stick you finger in the pocket and see if there is water in it. If there is, the drain below and to the right is plugged and just needs to be cleaned.

gaggia syncrony logic not dispensing water. Just drops pods and red light comes on. have cleaned brew unit shower screen and dispenser tube. still have the problem

Lubricate the brew unit with a food safe grease this should help.
The brew unit becomes stiff and fail to load up fully this stops the water being dispensed
