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

Step 3: Battery

Though this is not a step to replace the  Li-Ion battery, I thought I would post a photo.

It appears that the battery is glued in place, but I think others have posted instructions on how to remove it.

Step 5: Test your work

It should be pretty obvious, but try brushing your teeth!
If you really need brushing instructions you probably should not be using a Sonicare

That said, if get all the way to this step and are stuck, click the link below and scroll down to page 7

Very helpful tip and good instructions. Worked like a charm. And then I fixed it again 2 days later, and today the screw came out again. I would like to know if there is a way to get a replacement screw -- or possibly the threads are loose where it is going. Has there been success with locking washers or any other fixes to hold these pieces together? Tx.

The repair worked perfectly , worked for a while then stopped again I took it apart again , put red lock tight on the threads of the screw and will try again ..I would however wright a small disclaimer telling people to be very carful unscrewing the end cap for the 1/4 turn , cause if you break the plastic locks you'll have a problem getting it back together !

Thanks, you saved me from a bunch of inconveniences during an already hectic time of year; greatly appreciate you posting this. My husband fixed it within 3 minutes for me (tightened a couple of screws). I also realized that a new brush head also was needed.

Thanks. You just saved me from having to buy a replacement for an otherwise fully functional brush. Unfortunately I was impatient and made a mess of the soft plastic base so I'll need to find something to seal it to make it waterproof again.
It lasted another year and a half before I had to tighten it again. This time I had a little trouble getting the inner component out but I turned it upside down and pushed the top down on to the top of a table and it came out easily.

Hi, followed your instructions, tightened the screw. powers on, but no vibration. Any other suggestions?

It is possible that maybe there is something else that is broken? For me it was just a loose screw.

If you locate the problem, please post a reply.

Good luck!

Twist the bottom plug in which direction?

I don't recall, but generally it is righty tighty lefty loosey (counter clockwise).

Thanks for your ideas! I had the same problem but in my case there is a part broken: So too late...
