Hello, I'm David. I'll be helping you solve your problem. Since this probably isn't something that can be diagnosed over the internet I'll say that Miele's are VERY complex machines. Most techs I know won't service them. It's possible that the diagnosis is incorrect. It might be worth a call to Miele factory service. http://www.mieleusa.com/service/index.asp
They can send out their own tech, or one trained on Miele, to give you a second opinion. It might be worth the service charge to know for sure. If it is the timer, and it's not available, there is nothing else that can be used.
