Not a question, more a comment. It was recommended to me by a dentist, who immediately gave me a golden tip that saved me money. Be sure to remove the chip (at the bottom of the brush head). After a certain time, the brush only provides 1 stroke of power! The chip in the brush head communicates with the body. If you remove it, you will have endless pleasure, clean teeth and neither a hole in your wallet nor in your tooth. I have my brush head for an average of 6-12 months. (No problem according to the dentist! As long as you don't press like a wild man, which you don't have to do here).

It may also be sufficient to simply switch off this replacement reminder. To do this, place the handpiece with brush head on the charging station and press and hold the on/off button for ~5 seconds. This probably has to be repeated for each brush head.

Answer

Thank you for the useful tip for the community.

Answer

Thank you for the advice. I also have the problem that the toothbrush (after a short time, a few weeks) only cleans with one stroke of power. But when I take the brush off, it shows me three strokes again. But which chip in the brush head do you mean and how do I get it out? 
Thank you and best regards

Answer

Does anyone have a tip if only two steps appear despite removing the chip?

Answer

Just bought this brush.
However, I miss a detailed manual.
There is only a quick guide included. Also no qr code for the download.

You would actually be entitled to a manual in German and in paper form!
I wonder where I can get that???

That's why I give Philips a minus point!

Answer

I would also like to know exactly where this "chip" is/what it is. Do you already know?
