I have a grey Dyson HP01 with an filter replacement message showing.  I’ve replaced the filter, and followed the filter replacement reset steps (hold power button for 6 seconds), though nothing works.

I’ve tried everything but nothing works.  From what I read online, this is a known issue with many HP01 units, where many have apparently had to send their unit into Dyson to be reset.

How can I fix this issue?  My very expensive Dyson is basically junk right now.
