A few days ago I wrote about how my wife’s Philips Sonicare electric toothbrush failed. The brush still turned on, so the battery was not an issue. After taking it apart I was able to discover it was a mechanical fault, a metal piece had sheared off making it so the head would no longer vibrate.
I was able to locate a new piece on Ebay to replace the broken hardware and it was an easy install to replace the part. The toothbrush is now functioning properly again, and a $10 part has saved us $100+ dollars on replacing the electric toothbrush.
A few pics of the replacement part and the broken part below. In the first picture on the right you can see the old part with the sheared off piece. The middle image shows the sheared off part with a metal attachment. A screw (not shown) goes through the attachment piece and through a part connected to the brush mechanism, and then screws into the captive nut on the sheared off part (you can see the bottom of the captive nut sticking out of this piece. The photo on the left shows the not tip assembly purchased from Ebay. You simply need to unscrew and then attach to the vibrating mechanism on the toothbrush.
We may not be able to fix everything, but we should endeavor to fix what we can rather than throwing something away.
