If the alarm light is flashing, this indicates that a component of the machine is missing or not inserted properly.

#The brew unit is not inserted properly.
##Remove the brew unit from the machine.
##Make sure the brew unit chamber is clean and clear of coffee grounds or other debris. Make sure the tracks for the brew unit are not blocked.
##Firmly reinsert the brew unit into the unit. It should click into place. To test if it is properly reinserted try removing it from the machine without hitting the push/press button. You should not be able to remove it. If you can go to the next step.
##There is a flap on the back of the brew unit, opposite the side that says push/press, that needs to be in a certain position.
###If the flap is down inside the square notch like the picture below then it needs to be pushed upwards. Please note that on certain units, especially newer Gaggia unites, a yellow plastic is used instead of black plastic to help make this part more easily identified.[[File:Brew Unit Flap Wrong Position.jpg|480px|thumbnail|center|Fin Positioned Incorrectly]]
###The flap should look like this when it is in the correct position.[[File:Brew Unit Flap Right Position.jpg|480px|thumbnail|center|Fin Positioned Correctly]]
##It's possible that the gear for the brew unit is in the wrong position. This video discusses how to trick the machine into resetting the gear to the correct position: {{#ev:youtube|https://youtu.be/NV_TppITQZI|480|center|||start=159}}
#The grounds drawer or drip tray are not inserted. If they are inserted, then they are not pushed in all the way or something is blocking them from fitting all the way back in. 
## Remove them and make sure there isn't any coffee grounds or other debris that could prevent them from seating properly. 
## Firmly reinsert them into the machine.
#The water tank is not inserted. If the water tank is in place remove it to make sure there isn't any debris blocking it from sitting in all they way and then firmly reinsert it into the unit.
#The service door that covers the brew unit is open. Make sure it is firmly clicked shut.
#The steam/hot water knob is not turned to the correct position for the desired function.
