To test your dishwasher water pump, first ensure the dishwasher is empty and disconnected from power. Locate your dishwasher's pump; it's usually at the bottom. Listen for a humming noise, which could indicate the pump is trying to work but is obstructed. For a thorough test, remove the pump according to the manufacturer's instructions and inspect it for debris or damage. Use a multimeter to check the pump’s continuity. If the pump has continuity and is clean but still not functioning, it might require replacement. Consider consulting a professional if you're unsure.
