This actually seems to happen when the switch has not been touched for a while. I have noticed it happen when the lights are in a dimmed state and also at full brightness.

This is a single light in our kitchen with 3 incandescent bulbs in it. I don't know the brand.

Nothing has changed recently that I can tell but this just started happening within the past few weeks.

  @Wayne-TP 

They are Globe Superbulbs - 100W - Incandescent - 3 total in the fixture (hangs down from ceiling a bit)

Is there any kind of limitation over max wattage on these dimmer switches? I'm not exceeding the 15A by any means.

Thanks for your help!

I have this same issue. I see many people have been complaining about it for years. Is this ever going to be resolved?!? I see that support just keeps asking the same questions and asking customers to jump through the same hoops. This is ridiculous. If you can't fix it, stop selling the product!!!! I ready to replace all my Kass products and I have many. 

I have three relatively new HS220 in our living room controlling three sets of 4 LED pancake ceiling lights per switch, they may be 9-11 watts each max.

One of the three HS220 dimmers is exibiting the same behaviour. Will randomly turn off and turn back on a moment later. We usually keep these on around 20-50%.

  @IanAC I ended up buying a new switch and since changing it out we haven't had an issue. Seems like this is being seen by enough that hopefully a fix can be found and that replacement isn't the only solution. I don't believe that switch was even a year old.
