My dishwasher will fill and drain fine but when it comes time to spray it just hums. I have taken everything apart and cleaned didn’t fix it. Is it the motor and pump that needs replaced or how do I test the turbidity sensor to ensure it’s not causing the problem?

Pump jammed or motor defective?

Is the hum coming from the main wash pump motor? If yes, it could be jammed up internally (maybe a piece of broken glass got caught in it?) or that pump is defective and might need to be replaced. Basically, if the pump is getting power it should be running. There should be nothing else that could cause its stoppage.
