This process will demonstrate how to remove the internal assembly and tighten the metal shaft on a Sonicare FlexCare toothbrush.
To complete this, you will need 5-10 minutes and the following:
Standard flat head screwdriver
#0 Phillips screw driver
A little common sense
Step 1: Disassembly
Remove brush head
Using a standard flathead screwdriver
Gently twist the bottom plug until it releases
Gently remove the plug
Please note the tabs holding the plug in place are soft plastic and look like they will easily break.
Holding the body, push down on the metal shaft. Because of the seal it will take a little effort so I used side of the handle on my screw driver to break the seal and push it down.
Pull the internal assembly out
