It is due to an NTC malfunction or a heating tube issue. Please press the on/off button to enter standby mode, then wait 5–10 minutes before trying again (make sure the device temperature is set above 100 °C). Continue operation only after the system has returned to normal. If the error code persists, please contact the after-sales service.
