Before consulting the maintenance department, please check the following points.
| Problem | Possible cause | Solution |
| Machine cannot turn on | ● Power cord plug is not plugged in tightly | ● Check that the power cord plug is tightly inserted |
| ● No power at the power socket | ● Check or change power socket | |
| The machine turns off automatically | ● The temperature of the machine is too high that it activates the overheating protection | ● Switch off and pull out the power plug, cool for a few minutes before using again |
| ● The air inlet is blocked by obstacles (e.g. lint, hair, etc.), which result in high temperatures, thus automatic overheating protection is activated | ● Switch off and pull out the power plug, clear and remove obstacles from the air inlet, cool for a few minutes before using again | |
| The machine has low airflow | ● The air inlet is blocked by obstacles. (e.g. lint, hair, etc.) | ● Clear and remove the obstacles from the air inlet. If there are other faults, they must be replaced at the designated service point as special tools are required |
