Siemens EQ.5 extraKLASSE (TE506F09DE)

Hello,
when I turn on my machine (Siemens EQ.5 extraKLASSE (TE506F09DE)), I hear the typical noise in a continuous loop and the display shows "Hotline fault".
When I read out the error codes, the following are displayed:
BMU 10785
M03F08H02
BMUN11035
M01F07H02
CVT 10499
M01F03H00
CVF 11358
M01F03H00
Can anyone help me find out what exactly is broken? Is it just the brew group that is broken or something more?
Thanks for your help!

If the soft buzzing of the ceramic valve can be heard continuously and the valve keeps turning, there is probably a control module defect.

Thanks swolle for the quick answer.
So you mean a part that costs about 300 €? 
The first two error codes refer to the brew group after all. Had hoped that I am with 75 €

The control module costs about 140€, if you know an electronics engineer who can replace the triac that is responsible for the ceramic valve on the board, it is only a few € in material.
