Dishwasher making whirring sound Appliance Repair Troubleshooting Questions › Category: Dishwashers › Dishwasher making whirring sound 0 Vote Up Vote Down Anonymous asked 8 years ago I have an LG lds4921 dishwasher that makes a whirring sound every time the motor turns. I have cleaned the impeller and the blade area, ran it with and without both but it still makes the sounds. Any suggestions?
