  1. Our winnex 5500-2 gave up the ghost this mornning. I’ve kept the filters clean and changed then when needed. Tried a new location to plug into, no luck. The power cord looks great. I’m out of ideas and hope you can help me. sincerely Kris Jacobsen.

  2. Thank you! I kept looking or the ‘button’ reference in the user manual. I didn’t realize it was recessed in the top panel and required the universal IT tool (paper clip)!! 🙂 Thanks a ton! I was searching everywhere in the app. That would be a great place for a backup method!

  3. We change the filter and make sure it was incorrectly. We did the paperclip and held it for five seconds. We did that procedure a few times red blinking Light still comes back on.

  4. Our Winix red light came on to replace the filter. We did that but now can’t get the red light to turn off. The reset button is still dark and the light to tell us to replace is still on. I don’t see any little holes for a paper clip to work. Ideas?

  5. Please delete my question about the light. I did find the tiny hole for the paperclip and it worked! Thanks!

  6. Old gal coming through sorry. I ‘m looking for that hole. My eyes are so bad I can’t see it. I have a 5300-2. Any help would be awesome!

  7. Where is the hole on the white large Winix plasma wave NK100. No hole next to any light on the top panel? I’m geared with my paper clip and ready. I’ve tried the front facing holes alongside the “auto” “night 🌙 “ and “fan” settings???? Thanks.

  8. I bought two C545 units at Costco a while back. After replacing the filters, I tried to reset by pressing a paperclip into the little hole, as instructed. The paper clip would not go in. My friends, who also purchased two units, had the same problem. Today when I talked to customer service, I tried even smaller diameter items than a paperclip. I tried a hat pin, a sewing pin and finally an embroidery needle. None would go until I finally tapped the top of the embroidery needle with a hammer. This did not work for the other unit. It appears the little hole is too small. One serious problem is that a unit may be out of warranty by the time it’s necessary to replace the filters so that the purchaser may not find out about the defect until too late.
