If the circulation pump has been removed to check for debris jamming the impeller and none was found, can the pump be tested before reinstalling by applying power or could that damage the pump? Doc Ryan has a great video for creating a test cord for testing a dishwasher water inlet valve. Could this same test cord be used to test the circulation pump and if yes with the pump removed what specifically would one look for - humming, impeller not turning, etc.?

The symptoms behind checking for debris jamming the impeller are the dishwasher fills with water, but then remains quiet and does not activate the wash arms.
