Hi molly girl.
You can try to clean your Brewunit. Most of the times when that message appears, it means the brewunit is dirty

You can have more info in the manual if you dont have it:

HI
If the brew unit is in the wrong position when inserted you can knock the lever off the microswitch in the back. If the lever is knocked off you will never get the brw unit miss message to go away. You will have to take the machine apart and replace the lever on the microswitch. Sorry
We made a modification to the brew unit that would prevent this from happening. We modified all the brew units on the compact machines before sending them out so we would never get them back for this reason.

Hello, my brewunit make a rackett when I turn it on ... then stops and says 'brewunit blocked ... anyone got any ideas ...

Hi If you remove the brew unit and put everything back with out it the brew unit. Turn th machine on and see if it will cycle? Open the door and look in the back where the brew unit was. There is a cog in the back with teeth. There are 2 large teeth, and they should be at the 10 and 12:00 position roughly. If they are anywhere else you have a broken drive and need to get the gears replaced. If they are in the correct position check the front of the brew unit where the circles are. There are 2 diamonds and they should be pointing at each other. if they are not you need to bring them together with the key tool. Insert it into the center of the circles and turn until they line up, then put back into the machine, and see if it will work. If it still doesn't you have a bad board.

Coffee fines and mineral scale build up in the brew unit filters and also in the creme valve. The pressure to pump water through the unit fails and the flowmeter tells the electronics that no water has flowed, it in turn stops all processes and displays "brew unit blocked" message. If you're handy, call Miele tech support. The'll walk you through how to remove the drainage cup screw off the left rear of the brew unit, get the brew unit out and return the gearing to home position. It's a 50/50 chance the gears will return or you will need a service tech to pull your coffee unit out and re-sync the gears to the electronics. That's of course if they didn't break.
This blockage is is prevented only by using the cleaning tablets and descaling tablets. Both need to be used as outlined in the instruction manual.

Check the shower screen in the unit it is possible that it is blocked with coffee oils.

Hi There is a test mode for the Digital and we can see if you have a bad power board. Turn the machine off in back. Push and hold the small coffee button and the menu button (top left) at the same time and while you are holding the buttons turn the machine on. Release the buttons and you should have numbers in the display. If you can push the bottom left button and the machine makes a sound like the motor is moving, turn it off and then back on. If you don't get the message now you should really clean and lube your brew unit.

The brew unit sensor may have become disconnected from the main circuit board. If you are very brave, you can UNPLUG THE UNIT, remove the top panel and check that all the wires running into the circuit board are connected.

Otherwise, the sensor may have failed and this will require service.
