Grinder spins but won't grind coffee

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 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.

- coffee-channel is stuck.

check google for calibrating/cleaning your gaggia.

Hi...Grinder blocked message is ..when you make coffee there is no current going into the grinder. In other words the grinder motor is blown(coil windings in the motor is blown). You have to replace the motor. The problem is common with Gaggia, Talea, Odea coffee machines. hope your machine is less than 2 years old to get fix under warranty.

Turn the big knob to the biggest number and the small knob the the -, then try again. You are getting a clog in the passage from the grinder to the doser because your grind is to fine. If it clears trun the big knob back to a number higher than you had before and the small knob to the position you had. Only turn the bigh knob to a smaller number when the grinder is moving. If this doesn't work you will have to clean the grinder and passages with a vacuum.

Does it sounds grinding beans or free spinning sound?If free spinning sound...Grinder mechanism is broken.

This normally indicates due to the grinder being set too fine or oily beans being used.
Try setting the grind on 7 .
If it still fails the grinder will need to be unblocked and serviced.

your grinding chamber is blocked, the same happened to me, did it struggle to grind before? try taking the black shoot out the top with the 2 screws( were you would put pre ground coffee in) take the brew unit out(along with the waste water and bean tray), and reach up to where there is a little spring, the spring controls a little door, if you open the door manually and clean out the shoot to the grinder( make sure the machine is unplugged for this), i used the end of a tea spoon and a little hoover. it should work after this 

check to make sure the blades are secured to the motor shaft. some have a set screw, some are positioned over a pin in the motor shaft.
