David, I`m glad I could help. I even had the PC board replaced under warranty but of course it didn`t help. The trouble was that the machine often would not go into full spin speed, or when going into a suds lock not reducing the speed as it should until the suds are cleared.
Of course as it is always the case with sporadic faults it always worked properly whenever a Miele technician had checked it. Think they just declared me nuts because they never could find the problem.
I have mine now slighty tilted backwards and it seems to like it a lot.
