SOURCE: Brew unit in Miele coffee system CVA615 block

It sounds like the connector or wiring that links the LCD display board on the door to the main PCB inside the coffe maker has become loose or damaged.
This would cause the text displayed to become scrambled.
Its a 26 way connector that is labelled JP16 (on the next model up) and is next to a large IC.

SOURCE: miele brew unit jammed and brewunit block is being displayed

There is a third solution. The brewunit drive motor has three contact switches that indicate home, preset (loading grounds, I assume) and make espresso. The problem is the three contact switches are all on one circuit, so the microprocessor knows a limit switch has been reached, but it doesn't know which one. The programming obviously assumes the limit switches are reached in the correct sequence. In my case, the microprocessor thought the brew unit was in home position when it was in the make espresso position. Miele technical support recognized this immediately, so it is a common problem. The solution is to remove the top panel of the unit, unplug the unit, unplug JP34 on the microprocessor board (four wires, red/yellow/brown/black, in the middle back edge of the microprocessor board). Plug in the unit, put it in maintenance mode, and press and hold the medium coffee button for several seconds. This will move the drive motor past the current limit switch. Plug JP34 back in, plug in the machine, and put it in maintenance mode. Press and hold the large coffee button for a second or two, maximum. Open the machine, and look at the brew unit drive male gear in the main machine as compared to the brew unit female gear. It will take several tries to get the male/female gears to match so you can plug in the brew unit. Once this is done, and the brew unit snaps in place correctly, place the machine in maintenance mode one more time and press and hold the Medium Coffee button to reset the microprocessor with the limit switches. You should be back in business!

SOURCE: miele coffee maker cva 4070

OK. Here's the deal. I struggled with this CVA 4070 (F 73) problem also recently, and even posted a questions in the cyber world about it. I jiggled, re-cleaned the machine, re-read the Miele manual, and scoured the internet for schematic drawings of this brewing unit's insides. No luck. Finally after finding out I'd have to pay $199 just for a service clown to walk in my front door, I said NYET!!!  I must solve by myself. If I can take apart & fix my Dyson, etc, etc, I WILL DO THIS TOO!!  (MUST HAVE COFFEE>>>)
Pull out the brewer, turn it a quarter-turn to your right, and look at the spot where that small black plastic piece -- shaped like a block "M" or block "W" -- should be situated. Pull it out, if it isn't out already. Don't worry about yanking it out or harming these parts, said the Miele troubleshooter guy in New Jersey on the phone. They're "made from the same plastic used in football helmets."  Okey-dokey. 
This approx. 1.5" wide, blocky plastic piece is part of the "slide" that takes the brewed coffee grounds into the waste container. When positioned correctly, it looks like a block "W,"  with the "wings" ointing up, and slides in just under a brown 1.5" flat piece. A small, down-facing tab on the brown piece clicks into the "W" piece and holds it in place. The "W" should feel fairly solid, although it is not rigidly in place, as the entire mechanism is a movable system to deposit the grounds in the waste receptacle. 
Put everything back inside your CVA 4070 "love" machine, hit "on," and wait for it to go through its warm-up.  No F73 message?  Yeah!  Mission Accomplished. You, like I, have fixed your Miele, saved your family relationships, and saved yourself a bundle from unnecessary service calls.

SOURCE: Miele CVA 4075 brew unit locked

Turn your machine off. Close the door. Depress <clear>, holding it down, press <on/off> then let go of both. Then press <clear> 3 times. On 3rd time, hold it until Service menu appears. Select <brew unit> then press left arrow to turn from <off> to <on>. Then press right arrow by <select> This will turn your brew unit drive to the correct position and you should be able to get your brew unit in/out and your waste container back in. Make sure to turn your machine off/on again to get out of Service Menu. I have a picture of how the wire needs to be inserted to get that back on. It's definitely not intuitive, but send another note with your email address and I can send the pics.

SOURCE: I have a three month old Miele CVA 4066. I have

your brew unit is clogged. It will need to be removed and cleaned every 24 hours as per the owners manual. There is a yellow laminated card in the box with the accessories that shows step by step how to perform the 24 hour maintenance. To prolong the life of the brew unit, make sure the coffee grind size lever is in the middle or to the right of center, rather than the left (fine) side. Also, you only want to use dry beans, preferably espresso beans. Oily beans like french roast will clog that brew unit up very quickly.

F73 is a bad brew unit. The cva 4070,4075,4060, and 4066 are designed to use espresso beans.
If you use an oily bean such as Starbuck's french roast, it will clog the filter in the top of the brew unit. If you catch it in time, you can just replace the brew unit. If you run the machine with a clogged filter long enough, you have to replace the brew unit and gearbox together.
Sometimes if you work with the tech support department, they will send you a brew unit to install yourself. If you live in an area that has Miele factory support, you may just want to get a service call. It is very important to rinse the brew unit every 24 hours, and to use the cleaning tablets in the trap door( not the descaling tablets) if not, the coffee oils build up and turn into a tar that will clog the brew unit. They run about 300 dollars so they are worth doing the maintenence on.

It say brew unit missing


The brew unit missing switch is inside the slot at top back wall where the top of the brew unit puts an angled piece of plastic into the slot. The piece is a slope like a nose so it gently pushes the switch as you instert the brew unit. See if the brew unit reaches this slot on the wall. If it doesn't the brew unit most likely jammed up and was removed while the gears were not in home position. Now the gears are not allowing the brew unit to return fully inserted.

If you're handy you can call Miele tech support and request they walk you through steps to diagnose this. They will discover if the gear is out of home position or not. If it is not and the switch is in contact with the brew unit you may be in luck, the swith is cheap. But if the electronics no longer reads the switch signal it's 800 bucks to replace. Good luck!

My meile does not make good coffe


Remove the Brew Unit from the maschine and clean it very well und running water. Thn go into the Main menu and switch back all settings to factory defaults. Then take a vaccum cleaner and put the pipe in the small hole where the coffe falls into the brew unit (knock a bit on the maschin inside). Put out the bean container and do the same with the hole where the beans go into the grinder. Then put everything back in and start a cleaning process for the brew unit (do it 2 times).
After that your Problems must be gone. The Problem is between the grinder and the brew unit. the grinded coffee has bee stuck and is not falling into the brew unit .... that happens when you use beans with lots of oil inside  .... or coated beans .... they "glue" the chute .....
