<p>I bought Phillips LatteGo 3200 machine. When it came, I put it together and during that I noticed there is a grinder coarseness knob. Out of stupidity, I tried to move it up and down.

<p>And now I wonder, did I brake anything when I moved the knob while the grinder was not running? Is there some setting linked to the knob position I messed up, and if so, is there a way to fix it?</p>

You probably didn't break the machine when adjusting the grind setting when the grinder wasn't in use.

The reason for this recommendation is that there might be a bean which is stuck between the grind disks. If you try to adjust the grind setting with a bean stuck in between then you might need a lot of force which the adjusting mechanism isn't built for.

If you try to adjust it and it and everything moves without too much resistance then there is probably no bean stuck in between and adjusting shouldn't harm the machine. If it feels like the knob is stuck when you try to adjust it then it makes sense to turn on the grinder so that the beans blocking the disks will be pulverized as you adjust the setting.
