The machine does not turn on

"1. Check that the power supply is working properly. During use, check for power outages, blown fuses, or loose or unplugged power cords.
2. Check if the household voltage is too low (below 167V). Low voltage may cause the hair dryer to stop working.
3. Turn off the hair dryer and unplug it. Check the air intake and exhaust vents for foreign objects, as these can prevent the hair dryer from operating.
4. If the hair dryer stops working during use, it may be due to overheating caused by a blocked air intake or exhaust vent. When the hair dryer overheats, it will automatically shut down as a safety measure. Let it rest for 5 minutes, then turn it back on to resume use."
