Question about Miele CVA615 Espresso Machine
After brewing a cup of coffee the "brewunit block" displayed. When I tried to remove the brew unit, it is jammed. This has happened before, and the arm that you pull with broke. I am reluctant to pull with any force. Is there something I can do to release the unit?
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!

The reset command sequence for resetting the brew to Reset Position is;
1. Close the Door.
2. Press and hold simultaneously the Hot Water and Small Coffee buttons.
3. While holding the buttons down, turn the mode knob to On with Light. At this moment, the screen will show a version number and other numbers. The unit is now in maintenance mode.
4. Release from pressing buttons.
5. Press and hold Medium Coffee button. This will move the grinder into "home" position for extraction and cleaning.

At the risk of stating the obvious (sorry!) you have probably already realised the brew unit can only be released when the unit is "aligned" correctly.
If the unit is half way through a cycle, compacting the coffee etc, it cannot be released because a small bucket shaped part of the brew unit holds it in place under a steam spout.
Ensuring the power is off, try slowly pushing down with a finger inserted just to the right of the "PRESS" tab. You should feel a small T shaped lever. In the aligned position it should be about 2cm or 3/4 of an inch from the base of the brew unit.
When you have returned the lever to this position you can remove the brew unit.
I believe there is a reset sequence but I'm afraid I don't know it (sorry).
By the way, if you are prepared to do a little swapping, the compatible parts for this coffee maker are made by Saeco, Miele just rebrand them and add 400% markup :-)
For example go here for the brew unit:
Cost is $84 but you will need to swap the spouts, mind you its saves you over a $100 by not buying from Miele.
I know this is a bit hit or miss, hope it helps
