The upper spindle on which the brush snaps into place appears to be constructed partially of plastic. While the brush is vibrating it rubs against a metal portion, especially when the user is pressing the brush against his teeth. My toothbrush now does not operate. Once even the slightest pressure is applied to brushing my teeth the vibration ceases. If no pressure is applied, as in not touching my teeth with the brush, the toothbrush vibrates as it should. This is poor design for the obvious reason - one has to apply pressure and in doing so the plastic part deteriorates making the electric toothbrush useless. Is this a know defect? Can I get my expensive toothbrush replaced? have you made alterations in your latest version? Thank you, Brian Rodgers

@vilkas1 that is a really good observation. iFixit is most likely not going to replace your toothbrush nor will Philips get any design ideas from us. I think this would make a great guide/wiki. Add some images to your question and let’s see if we can convert it to such. Use this guide for that. Show where you think the design fault is present. It might be worthwhile to send your request to Philips depending on which country you are in. Who knows, you may just get anew toothbrush from them.
