Question about Krups F203 Grinder
You may really have overheated it and it may not have a self resetting thermal fuse. Probably best you say nothing and take it back for repair or replacement under guarantee. When you are up and running again do much less grinding at one time.

I had the same problem, took it all apart, separated the two halves, and looked into the guts of the machine, not an easy task. Fiddled with this and that, and looked at the back of the switch mechanism, and heard it making a 'click' when depressed, so put it all back together, to no avail...It turns out the grinder needs to have two limit switches engaged, one between the lid of the ground coffee hopper and the underside of the grinder hopper housing, and the other between the grinder lid and the base of the unit. This last limit switch was my problem, it seems the lid wasn't making contact with the limit switch, so the unit didn't run. I cleaned out the narrow gap that the grinder lid sits within, pressed the lid down until I heard a small 'click' , pressed the on switch, and presto! it works. You can see this very tiny switch if you take off the grinder lid, and look in the narrow gap it sits in at a position of about three o'clock ( the back of the machine when viewed from the top being 12 o'clock. Hope this helps anyone else who can't find their receipt within the one year warranty period. This is the best burr grinder I've found for the money, and I'm glad mine's still o.k.

Open the grinder by removing both knobs.
The front knob is held in place by friction. Use two flat head screwdrivers to pry it off.
The side knob is held in by tabs you have to push. Pry forward to expose the tab, and use another screwdriver to press the tab, and use the other screwdriver to press the tab on the other side.
Now look at the bottom of the grinder. There are four tabs on the outer shell, use screwdriver s to pry the tabs to separate the bottom of the grinder from the shell, and pull off the shell. Your fuse should be attached to the motor wiring coil.

Most plastic products contain enough carbon black to neutralise this problem. Obviously not with yours.
Try a camera accessory cleaning cloth - specifically anti-static.
Cleaning less often will also help, and maybe a quick brush out would result in less mess.
Natural fibres like cotton cloths or bristle brushes will also help.
Coffee naturally has oils that, if left on, will eliminate this problem anyway.

Testimonial: "Thank-you - unfortunately, reviews I've found about this coffee grinder indicate that it's a common problem, but your suggestions has helped some."
My grinder stopped suddenly. Open the cover(s) by prying at the cracks with a butter knife or flat head screw driver.
The thermal fuse was good in my case, as were the interlock switches.
The circuit board was burnt around a large power resistor but I could figure out which component was bad. I simply cut out the timer control completely. One of the black motor wires now connects to the red wire from the bottom interlock switch and the other black wire connects to the blue AC power wire. I may put in a button switch but it works great by using the lid interlock as an on/off switch.

SOURCE: coffee grinder will not turn on
I recently had this same issue - it turned out that the lock switch no longer engaged because the spring came out of alignment after the unit was dropped. Chances are you have a similar issue. You can test this by using a small screwdriver to press down on the safely latch and then pressing the ON/OFF (careful of the blades!!). then you can easily fix it.
