A:Answer Hi Rita,
When you pause a cycle by opening the door, press the Start button before closing the door to continue the cycle. Push the door firmly closed within 3 seconds of pressing the Start button. If the door is not closed within 3 seconds, the cycle will not start. You can check the link below and see page 11 (BASIC GUIDELINES) for reference.
