Hi, hoping someone can help me! My washing machine seems to just pulse on and off when the drum is turning without getting up to full spin speed. You can actually hear the motor pulse on and off and the drum speeds up and slows down with each pulse. Have tried the diagnostic mode and it will spin full speed during the spin test but goes back to pulsing during the normal wash cycle. Does anybody have any ideas what I can check? I'm a heating engineer so am quite happy to test components etc if anyone can point me in the right direction! Many thanks
