My Philips Barista Brew Espresso Machine is not grinding coffee beans

Firstly, ensure the bean container is sufficiently filled with beans. If your machine has two bean compartments, make sure the one in use is filled sufficiently.
 
Then, check if the ground coffee outlet is clogged with ground coffee. In that case you can clean it with the brush (see image below), for more detailed instructions please see User Manual.
 

If the On/Off and 1-cup Espresso buttons stay on after first-time use or after the first cycle of descaling, it means the machine needs to be flushed before you can use it.
Here's how to flush the machine: 

1. Ensure the water tank is filled and place a bowl under the coffee spout.
2. Press the 1-cup Espresso button to start the flushing process. 
3. During flushing, the 1-cup, 2-cup, and Americano buttons will light up one after the other. 
4. Once flushing is complete, the machine lights will stay on steadily, indicating that the machine is ready for use again.

Please make sure the bean container is sufficiently filled with beans. In case your machine has two bean compartments, make sure the one you are using is filled.
 
If you do not hear the grinder motor turning whilst grinding, the bean container is not placed correctly. Make sure you align the rib of the bean container with the slot on the top of the machine, press the bean container down, and rotate it clockwise to lock it into the machine.
 

There is chance that the grinder is stuck due to foreign particle or a stone. Please, remove the bean container from its position and detach the internal grinding wheel. If blocked by a particle or stone some force may need to be applied. Clean the internal grinding wheel and grinding chamber and remove possible blocking particles (see image below). For a step-by-step guide please follow the cleaning instructions in the User Manual.
 

After changing the grind setting towards finer or coarser, make sure you adjust the quantity of coffee being ground too. You can find detailed instructions on adjusting the dosing in the User Manual.
