Why is my LG dishwasher not turning on?

Your LG dishwasher may not be turning on due to a variety of reasons, such as a power issue, a faulty door latch, a malfunctioning control panel, or a problem with the circuit board. It is recommended to check the power supply, ensure the door is properly closed, and inspect for any visible signs of damage. If the issue persists, contacting a professional technician for further diagnosis and repair may be necessary.
