If this valve has failed or is clogged the dishwasher won't clean the dishes properly. The valve cannot be cleaned or repaired and should be replaced.

If the dishwasher won't clean dishes the circulation pump might have failed. If there is no noise coming from the circulation pump after the dishwasher has filled, the pump itself might be burned out. Unfortunately, there isn't any easy way to test the circulation pump. If other components have been tested and they check out OK, the circulation pump might need to be replaced. This job is somewhat difficult but many DIY'ers are successful replacing the circulation pump.
