We just went through the same situation. We opened the top the Magnifica to get to the grinder and removed the four screws to seperate the grinding pieces. Inside we discovered two black fosilized beans/stones! We removed those, cleaned out all the bean dust and it is working like new! Took about an hour.

There are two reasons for this usually. Either the grinder is jammed or the grinding wheel or wheels have broken. Your machine needs to go to a repair shop to be looked at.

Had this problem with my burr grinder, coffee (or something else) is clogged between the burrs and the output chute, so new coffee can't feed in from above. You can try a few things:
1. Unplug and try to dislodge the blockage from underneath with a toothpick.
2. Disassemble and remove the blockage.
3. I've had luck with drizzling a little bit of cooking oil on to the burrs,letting it soak in a while, then running it, the clumped coffee came loose. It made a terrible mess in the bin, but I ran a couple cups of beans through and it cleaned up the oil.
Good luck~
Testimonial: "You were right about the clog. I tried the white rice fix seen elsewhere and it's grinding perfectly again. Thanks."

Fill beans before they run out!
If you hear the grinder running empty, press the same button you pressed to start making coffe to cancel the current cup -or, if some beans were ground, stop the water a bit earlier to make a shorter coffe using the same method (press the button you pressed to start the cup). The auto-detect of beans missing is a very minor and largely useless feature.
In our case we were lucky. Grinder was blocked by the beans. This is what I have done with our Delonghi 5400. It looked fiddly but was quite simple really. I started from the back panel. Once back panel was removed I had access to 4 corner screws that remove both side panels. Now that give me access to 4 corner screws that hold top of the machine. I l also had to unscrew 5 screws that hold coffee container in place. 4 are visible once the coffee beans container is open, but the 5th is hidden in the middle of adjustment arm with a black cap on top.(adjusting how fine you grind). I used small sharp screwdriver to lift the cap. Once all are out I removed the top of the machine and then the funnely coffee container too. That exposed grinder assembly. Top of the grinder is actually loosely sitting in the lower part of grinder. Twisting it counter clock should release it I Think. Our was not budging, and I had to completely remove the grinder and detach motor but that is quite obvious too, and probably not needed. I just wasn't sure what I was doing. Our machine was out of warranty so... Would be nice if we had some schematics.
