The washing machine works when you close the door and stops when you open it due to a safety feature called the "door interlock" or "door lock." This feature is designed to ensure the safety of users and prevent accidents or injuries during the washing process.
Here's how it works:
Safety During Operation: When you close the door of the washing machine and start a washing cycle, the door interlock engages and securely locks the door in place. This is to prevent the door from accidentally opening while the machine is in operation. If the door were to open during a cycle, water and detergent could spill out, and the spinning drum could be hazardous to anyone nearby.
Interruption of Power: When you open the door during a washing cycle, the door interlock disengages, and power to the machine's motor and other components is interrupted. This safety measure ensures that the machine immediately stops any moving parts, such as the drum, to prevent accidents and injuries when accessing the interior.
Pause Function: Some washing machines have a "Pause" or "Stop" button that allows you to temporarily halt the washing cycle without opening the door. In this case, the door interlock remains engaged, and the machine will not resume operation until you press the "Start" button again.
It's crucial to follow the safety instructions provided by the manufacturer to avoid potential hazards and ensure the washing machine functions as intended. Never try to force the door open while the machine is running, as it could lead to damage to the machine and pose safety risks. Always wait for the washing machine to complete the cycle and for the door lock to disengage before opening the door to remove your laundry.
