The Dyson Airstrait™ straightener doesn’t have universal voltage. Each appliance is designed for the specific voltage of the retail country. Therefore, as with our Dyson Supersonic™ hair dryer and Dyson Airwrap™ multi-styler, it won’t work in countries with a different voltage, even with a plug adaptor.
If travelling, check the voltage of the country matches that of your Dyson Airstrait™ straightener. You can find the voltage for your appliance in your user manual.

This is called Auto stand-by mode. Because the appliance is powered off, you need to TEST and RESET again every time before you power on the appliance.
If after pressing TEST and RESET, the RESET button doesn’t pop out (red collar isn’t visible) and/or the LED lights up or blinks red, do not power on your appliance.
Immediately turn off the mains power switch and unplug the appliance, and contact the Dyson Helpline on 0800-298-0298.
