Question about Coffee Makers & Espresso Machines
I'm getting the brew unit block message but after a lot of cleaning and fiddling it seems more like the water is not getting into the brew unit 'spout' at the side. Is there a way to 'debug' this?

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.

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!

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.
