Hi, Thank you for your question.
There may have been a power surge while you were away, anyway unfortunately the main control board has failed;-(
This is an easy to replace part no soldering required and I will help you replace this board.
The best place to get that main board is: http://www.ransomspares.co.uk/
Please call: 0844(###) ###-####a href="http://www.ransomspares.co.uk/" target="_blank">Home » Parts » Brands » Siemens
Its best to call to order this main control board because they dont list all parts on their site, and also you will be sure to get the correct one and they will ship same day you call:-)
I wish I had better news for you, I really do.
In any case, I will stick with you until this is complete.
