Hi guys. I'm hoping someone might be able to help me with a question about my dishwasher. I have an Asko D3251 which they will have to pry out of my cold dead hands. It doesn't matter what you put in it or how burnt and dried on it is, it comes pristinely clean every time. Granted, the use of space is not the best compared to an American machine, but once you learn how to load it, you can stack and cram it jam packed full, and everything will be spotless at the end of the cycle. I literally have NEVER had anything come out of it that wasn't spotless... until now.
So...it's a machine that alternates between the bottom and middle wash arms. Of course, that means it uses a diverter valve. About a month ago, I had noticed it wasn't switching back and forth like it should so I did a heavy cleaning cycle using a cleaner and citric acid figuring the valve might be clogged with some food particles. That worked for about a week. Sine then, only the lower spray arm will work. If I extend the cycle, the top rack will come clean, but its not perfect... not what I am used to from this machine.
My question is, how can I know whether the problem is mechanical (i.e. the diverter valve needs to be replaced) or the problem is electronic (i.e. the board is no longer signaling the valve to open and close)? I can easily fix the former myself; however, unless I replace the entire board, I have no idea about repairing electronics.
Any help from you experts is greatly appreciated. I really don't want to replace this machine since it washes dishes so very well. It knows you need HOT water to wash dishes and will heat it to 170 degrees if you want it to.
Thanks guys and Happy Thanksgiving to everyone.

Thank you, Alex. I appreciate it. It would appear the problem is most likely the diverter valve and not the electronics. I'll check it as the guide specifies. More than likely I will have to replace it...and it's not a cheap part. Better than replacing the whole machine, though.
