Sonicare HX9340 register

Hi Noel:
The instructions that came with it should tell you.
I'd guess at 2 possibilities:
1) Needs re-charging
2) Brush needs replacing

Are you sure the brush attachment is "tight" to the handle? Do you have a new brush to try? It should confirm handle is bad or it is the brush attachment "tightness" .

maybe the battery

Probably two reasons for this. 1) the contacts at the base of the brush are not clean which will prevent proper charging , the low battery beep is telling you to recharge.2) the battery needs replacing.

My flexcare began randomly turning itself on about a week ago. When charging it would vibrate a pattern of one short, then 2 short bursts. After talking with tech support and finding my flexcare was out of warranty, fixed it myself.

I opened the the base with a flat head, disconnected the battery (my model did not have a soldered in one) and wiped out the condensation in the housing and on the brush. I put it back together and it works as before. YMMV

Let me know if you have any issues. Hope this helps!

Please rate this solution and comment!

Firstly, please check if the metal shaft is loose. Its that part where your brush head connects with the toothbrush handle. If its loose then it has to be replaced. Contact Philips support for a replacement, if its under warranty.

Please plug in the charger with the handle on charger base and hold the on/off button for 7 seconds in order to hear two beeps. Please hold the on/off button again to hear one beep. Do you hear two beeps followed by one?

If yes, then your unit has been reset. Please leave it on charging for 24 hours and then use it again. It should be able to hold charge now.

This happened to me as well. In my case, it meant that one of the metal bars for the brush head broke. If you unscrew the brush from the base and look at it, touch the metal stabilizer bars inside to see if one of them is broken. If so, a simple brush head replacement will fix your problem.
