Hi, I have a Dyson Supersonic™ hair dryer, which is still in warranty (purchased Oct 2022) and it has just completely stopped working It shows 3 flashing white lights. I've read the troubleshooting page and cleaned the filter (NB: which I do regularly anyway), but this has made no difference at all. It still won't work at all. Has anyone else had this problem and can suggest how to resolve it? Thanks

There are a few things we can try.
Normally, this is an overheating issue and normally caused by hair being caught in the machine or a power-draw issue. We will help you resolve this.
1. Please try this in an another room, and plugged directly into a wall outlet - not any kind of strip.
2. Next, let's do a deep clean:
Use a damp lint-free cloth to wipe the inner mesh (IMPORTANT: do not use other cleaning products/solvents or liquids).
Leave the machine to sit for 5 minutes.
Brush the filter mesh firmly with a new or lightly used clean, dry toothbrush for two minutes (be sure to brush the entire filter mesh, brushing up and down and side to side).
Wipe the filter mesh using a dry, lint-free cloth.
Rotate the filter cage back into position, ensuring the correct alignment.
REMINDER: Rotate clockwise to lock before use.
Run the machine for up to one minute. The dryer should function as expected.
If the issue persists, please contact support for your options.
