To test your dishwasher's circulation pump, first disconnect power to the dishwasher for safety. Access the pump usually located beneath the dishwasher, after removing the kickplate. Listen for a humming sound when the dishwasher is supposed to be circulating water; no sound could indicate a problem. Another method is to check for blockages or debris in the pump or its filter. If the pump is not operating despite being clear of blockages, it may need to be replaced. Always consider consulting the dishwasher's manual or a professional for guidance.
