Hi everyone,

We recently bought a Dyson Find+Follow™ Purifier Cool PC3, and considering the price, this issue is pretty disappointing.

When we turn it on after it has been powered off for a longer period, the small display doesn't show the usual digital animation/graph. Instead, it turns completely white. The purifier starts blowing air for about 3–4 seconds, then completely freezes. None of the buttons respond, and the only way to recover it is to unplug it from the power outlet and plug it back in.

After that, it starts normally and works perfectly. If we switch it off and back on again after only a short time, everything is fine. However, if it stays off for a longer period (for example a few hours or overnight), the same white screen and freeze happen again on the first startup.

The exact same behavior occurs whether we start it using the power button, the remote control, or the Dyson app.

Has anyone experienced this with a PC3 or another Dyson purifier? Is this a known software issue, or does it sound like defective hardware? Before I contact Dyson support, I'd love to know if anyone has found a solution.

Thanks!
