Gaggia Titanium Gear Behind Brew Unit Too Far Left

Be for you send if off take a look at you-tube. type in stuck brew unit and one of the videos walks you through this problem.

If you make a pre-ground shot but don't put any coffee in it, and it does the same thing you have a blockage in the brew head.
If it run normally, your grind is to fine. Turn the grinder knob to a larger number. It takes 3 times to change to the new grind.
If it still dribbles, remove the brew unit (behind the door)
Holding the handle, the top left side is the brew head. There is an outlet pipe that exits the front side towards the door. 2 screws hold it to the top. Remove the 2 screws while holding the manifold. Once they are removed, lift the l assembly off (becareful, there is a spring and inside a steel ball (don't loose it or your out of luck). Turn the brew unit upside down while holding the brew head in your other hand and the steel ball should fall out. If it doesn't come out put a towel down and tap the brew unit on the towel. This should force it out.
Now remove the brew screen, by holding the screen with your finger and twisting the thumbscrew (remember thumbscrew, DON'T use the key to install the screen, use your fingers.....
Once the screen is out look at where the screen was. There are 2 holes. 1 big one in the center and a small one to the side.
Now use air to blow back through the opening where the steel ball was to clear the opening. Once its open, clean then reassemble. Brew unit on towel right side up. Drop the steel ball in first. Then the spring.
Then place the manifold on top of that with the pipe towards the door. Insert your screws (I turn them backwards a little with a little downward pressure until they feel like they drop into the threads. They should turn down easily, if not back them up a little more ( we are trying to find the old threads) and tighten. Install screen, and tighten with your fingers. The screen just needs to be flush with the bottom of the brew head.
Run another pre-ground without the coffee and rinse it out. Do this once in a while to prevent this.

Try taking the brew unit out, and clean the area inside the machine for coffee grains before reinserting it. There's a tiny sensor for if the unit is inserted, but it can be confused if the machine gets messy inside.

If it is coffee colored water, check the chamber under the white plastic valve behind the brew unit, that might be blocked with coffee grounds. If it is clean water one of the lines might need new o-rings.

Give the brew unit a good wash,then lube all the moving parts with food grade grease.
If you are able dismantle the brew unit and wash in warm soapy water,this removes coffee and any old lubricant.

Try cleaning and relubing the brew unit.
If that fails you require a new main board.

If steam wand is not blocked then the problem is on the inside of the machine, try descaling the machine that might clear the blockage in the steam line.

Hi
You have 2 knobs in the bean hopper. The small one is set to the most positive. Turn it back 1 click from the plus and that should take care of your problem. When you have a clean brew unit it will make the first coffee but a little coffee is left in the brew unit and when it tries to make the second coffee a full charge and the little that was left cause an over charge, and dumps the coffee without making anything.

Mine had the same problem. Take out the dreg drawer and brew unit. Then you will see a plastic cover roughly in the middle of the machine (behind where the brew unit was) that is held in place by two philips screws. Unscrew the screws and take out that small cover. It is probably filled with coffee grounds that prevent water from dripping out through a dripping hole. Clean out the grounds and you should be all set.
