You can only get that wheel as part of the grinder, it is not possible to remove the burr to replace the plastic part. It's factory fit during manufacture. There are 2 reasons I'm aware of to cause that, rarely it can be a stone in the beans but more likely you have an internal leak causing the grounds to bind up together from the steamy environment within the housings. Also if the relief valve in the distributor is sticking it can cause the chamber to stay very wet.

Insert a small standard screwdriver in the slot in the center of the bottom. Turn the blade slowly until you feel the screwdriver catch in the slot. This holds the motor still so you can simply unscrew the blade counter-clockwise. Do the same to hold the motor from turning while you screw the new blade on clockwise.

I have the same issue. You need to take both dials off, then on the bottom, there are 4 tabs on the inside. Seperate the halves and you will see them. Towards the front and halfway back. Pry the halves apart enough to push the top towards the bottom and it slides apart pretty easy. The tricky part now is finding the replacement part. I have super glued my switch and I want to do something to try and repair it further. Maybe epoxy. I called Krups and they can't sell the part to me. I called one of their service centers and they can't sell the part to me. So, if someone knows where to get the part, I am all ears :)

There is a small slot on the bottom for a flat screwdriver to lock the shaft in place. Then unscrew the blade.

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.

Mine had the same problem ... all the lights are on, grinding works fine, but no heat on the plate, and no dripping of water.
After a weekend on the workbench, I mastered this machine. The KM7005 has 2 x MicroTemp G4 thermal cutoff (TCO) fuses which interrupt the Live line, for overheat protection. Mine didn't overheat per se, but the TCO blew anyway. Not reset-able ... need to be replaced with a soldering iron. To date, I have helped 13 people on this site fix this exact problem.
I'll be happy to advise you to fix this, or fix it for you. Write me at [email protected].
