After reading the Technical Manual I determine the Control board was defective. I followed the instruction in the manual to remove the old part. installed the new part and started washing again.
It was not hard to replace, just ensue that up remove the button-pins, the control knob with the stick attached and Led Display from the old part and install them in the new part before you start installing the new part. The cost on the board is less then 1/4 the cost of the machine; our set is 8 years old...Job Well Done!
