Phillips Sonicare 4300 (HX680C) - Fix Unpleasant Noise

Difficulty

Easy

Steps

Time Required

30 minutes

Introduction

Toothbrush had become very noisy (my daughter refused to use it saying it made her head hurt). Repair was easy - just tighten a loose screw inside.

Step 1

As other sonicare repair guides show, the base plug is only held in by friction. If you squeeze the sides it will open a gap you can slip a screwdriver in and lever out the base. A bit of cardboard protects the sides from cosmetic damage.
Have a look to an alternative opening procedure.

Step 2

There are 2 tabs that prevent the insides sliding out. Release these with a small screwdriver while pushing the metal shaft at the other end, and when both tabs are free the innards will slide out.

Step 3

The screw circled was loose. Tightening this fixed the unpleasant noise. I had to use threadlocker to stop it coming loose again.

Was hoping this would be the fix for mine. Turns out the hole cracked along the horizontal, so my link rod can no longer hold on.

Vielen lieben Dank für die Anleitung, somit konnte ich meine Zahnbürste wieder benutzen. Ich finde man sollte wieder mehr reparieren und nicht nur weg werfen.

What is the size of that screw? Totally stripped mine

Screwstripper -

I believe I used a Phillips #1 on that screw. #0 seemed too small to me.

BTW, that Phillips #1 was on my HX686P (purchased as one of a pair at Costco in the US, which seems to be the same as an HX6829 when I try to look it up on Philips' website in their troubleshooter).
