Introduction
If your Sonicare is not as powerful as it used to be it could be because of a misalignment of the magnetic motor, e.g. if it's dropped. Philips built it like this on purpose and you need open the toothbrush and realign the magnetic motor.
Caution: Please only proceed if your toothbrush is out of warranty. If you are still within warranty then bring it back and get it fixed by professionals at Philips for free.
What you need
-
-
First you need to open the toothbrush. This can be achieved by applying pressure to the lower end of the toothbrush which will alow the removal of the bottom cap.
-
To protect the toothbrush from being mared by whatever tool is used, apply some cardboard or similar between the tool and the toothbrush
-
-
-
Once the bottom cap is removed, use a screwdriver or a knife to release the actual insides of the toothbrush.
-
There are various How-To's on how to do this. I would recommend to use Philips Sonicare DiamondClean HX9340 Battery Replacement
-
-
-
-
The magnets are secured by two screws. One is easily accessible on the back of the toothbrush.
-
The screw is mounted in a slot to allow for some adjustments. For whatever reason the screw has moved to the top of the brush, this will let the Magnets touch the driver which reduces the motion and power of the brush significantly.
-
Loosen the screw on this side.
-
Repeat the steps in reverse order to reassemble your device.

Good manual, I could fix the gap between the magnets. However, that was not the problem in my toothbrush. After pressing the power button the light for the selected program flashes once and after that all flash on and the toothbrush shuts down. It refises to start anything, it's almost as of there is a counter for the maximum amount of charges.
saved me from buying a new toothbrush, thanks!
Have the same question as Clys.Wish I could know the correct gap measurement.I also used a credit card,which measured .9mm.Maybe 1mm is the correct gap.I know that if I contact Philips the chances of reaching anyone knowing anything would likely be impossible.If I bought a new brush,took it apart,that would be a way of finding out.
