The equipment cannot blow hot air

"1. Check the power supply:
Make sure the hair dryer is plugged into the power outlet and check if the switch is turned on correctly.
Check the power cord for any damaged or worn areas.
2. Select the hot air mode:
Confirm that you have selected the hot air mode. If the switch button is pushed to the one-button cold air, the device will not produce hot air. [One-button cold air button as shown in the attachment]
3. Clean the filter:
Regular cleaning of the filter screen can prevent the accumulation of dust and hair, ensuring smooth airflow. Blockage may cause overheating protection of the heating element, thereby stopping the hot air.
4. Temperature adjustment:
- After the above steps are checked, let the equipment stand for a period of time; then switch to the hot air test to see if there is hot air blowing out
If the above investigation is ineffective, please arrange for the equipment to be sent for repair and testing."
