Which ever program i choose when it comes to centrifug the button begins to move clockwise , toogeling, forever. In the manual it says to switch off the machine move the progam button to "dot" sign and turn it back on. I did all that, the button did not resume the toggeling throw programs but i encounter same problem when i start the next wash program. At the centrifuge the stort repeats itself. any advice ? The machine works perfectly othewrwise.
