Center arm not moving
Whirlpool dishwasher, not sure what the model NAME is but the Model number is wdf560safm2.
i've replaced the circulation pump, water inlet valve and the center spray arm. the piping going up the back of the dishwasher isn't clogged as far as i can tell. the rest of the arms spin, but the centre arm refuses to spin? What else could be an issue?
