What Do You Do to Fix the 4E Error on a Samsung Dishwasher?

This error code occurs when the system fails to detect water in the tub for 5 minutes after the launch of the machine.

Check the machine. Be sure that the water supply valve is on. Disconnect the dishwasher from the mains and stop the water supply. Also, disconnect the inlet water line and check the inlet valve for blockages. If it is blocked, replace the valve. Make sure that the valve’s wiring is ok and there are no loose connections. If the activation of the valve does not work, replace it. The water inlet valve may fail due to:

  1. A foreign object blocking it.
  2. Faulty wire harness and/or loose connections (the valve’s coin is not connected).
  3. Hot and cold water reversed.
  4. Lack of connection between the dispenser and drain hose. Please, check the transparent tube for damage.
