Where do you get a replacement shaft? I can't find any online

You don't need to pry the bottom plate off and risk damaging the seal. Simply apply firm pressure on the shaft against a table while simultaneously wiggling the bottom plate back and forth with a large flathead screwdriver inserted into the charging hole on the bottom. It will pop off smoothly leaving the seal untouched and not scratching the housing or charging plug.

Like the previous comments I also am looking for the replacement shaft. If anyone has found a source please leave a comment with regards to where they can be found.

Thanks for the help

Like everyone above, I can't locate the "replacement shaft". Anyone have any ideas who might have one? A $179 toothbrush should last more than the one year warranty! Is the Braun Oral-B any better?

I need a replacement shaft also. Where do we order one?

Same story.I contacted Philips and was told they reserved that part for warranty repairs.I told them I might buy a new one,take the part out and return for refund.I wonder how anyone would feel,if they bought a car and the company wouldn't supply a repair part,after warranty ran out and no one else made the part?

+1 Also looking for a shaft replacement... Anyone?

Victor Marquez - Reply

Yes - search eBay for Genuine Philips Sonicare Vibrator for HealthyWhite FlexCare HX6710/6930/6950. They're sold by Gadget Salon. It came with the whole vibrator assembly, which was much easier to replace than the shaft alone (steps 5-8 no longer needed). Simply desolder the two red wires, pop the whole thing off, put the new one on and resolder the two contacts. The brush is like new.

Also - reference the steps above, step 2 is unnecessary. Simply roll back the rubber cover a little bit and, while holding it out of the way, push in on the shaft (step 3) and the whole innards come out. I used a large screwdriver in the charging peg hole on the bottom to gently twist the bottom cap back and forth a little bit to loosen it while pushing. In this way I avoided marring the bottom of the handle.

I have 2 Sonicare handles with loose shafts. Do you have any idea what causes them to go bad? Is that screw sheared off from the vibration? Was there a little ring that fell out somewhere along the line?

Great suggestion. Just ordered the Genuine Philips Sonicare Vibrator for HealthyWhite FlexCare HX6710/6930/6950 off eBay. Thanks for the suggestion.

I just ordered mine! Thank you, thank you for your suggestion. The shaft in my brush sheared at the screw. Finding parts isn't easy. Great finding your tip!

Also ordered thru GadgetSalon on eBay. However, I determined that merely replacing the broken shaft, and not the entire vibrator unit, was a less invasive solution, and no soldering. Worked like a charm! Thanks to all!
