Can anyone help me? I have been using the AC2887/10 for 16 months. During this time I have already had to change the white Hepa filter (display message A3). However, I have never had to change the black FY2420/30 activated carbon filter. I replaced the Hepa filter after the message A3 appeared. The message C7 for the activated carbon filter has never appeared, but the filter has long since reached the end of its service life (12 months according to the manufacturer).
Mine has already been running for 16 months. I reset the hepa filter after each replacement with the arrow and clock button. Am I doing something wrong? How can I now manually reset the activated carbon filter counter? Is that only possible if I reset the HEPA counter A3 first? Thank you!
