Oral-B Vitality: The motor is spinning but the head doesn't move

Mon, 04 Dec 2023 07:33:52 -0700

Hi,

I noticed this tiny lead screw had probably fallen from its place:

Any idea how this mechanism works and how to disassemble/fix the head, it's still new.

Edit: actually it's not a lead screw, it's a pin with a spring, I tried pushing it up but it's not.

Thanks.

Oral-B Vitality: Oral-B Vitality Type 3709 only works for few minutes

Sat, 09 May 2026 16:26:16 -0700

Hi. I have this weird issue with new old stock of this 3709 model where it would work for few minutes or maybe longer without brush head attached. When it nearly starts to act up, the toothbrush is behaving like the battery is nearly empty where the metal end vibrates very weak until it stops. When it stops, I could hear some sort of humming sound. I tried to move the metal end left and right, it seems like the motor inside is struggling to work. It feels like it's trying to move to vibrate, but it failed.

I let the toothbrush off for few minutes and after that, it starts working again at full speed like fully charged battery until few minutes of using it that the metal end gradually gets vibrate weaker and eventually stopped working again. Note that I didn't put it in the charger. I let it cool down for a while and the cycle repeats. Hopefully someone can help me. Thank you.

Oral-B Vitality: Is anybody knows what is the IC controlling the toothbrush?

Tue, 10 Oct 2023 08:42:24 -0700

I have two toothbrushes Oral-B D100 (type 3710) for kids with the same problem : They're dead ! I opened them and confirmed the voltage (1.2Vdc). The power button did nothing. The problem seems to come from the 14 pins IC inside. It it a CCE7102 chip, but there is no information on Internet about this IC.

Is anybody can tell me what is the purpose of this chip (probably a PIC or something like that) and how to confirm if the problem really come from this one ?

The battery is good, the motor works (as soon as I put 1.3Vdc on the motor, the head start to wiggle. If I bypass a transistor controlled by this IC just beside it (shorting emitter and collector), the toothbrush start normally (until I remove my short).

I know it is just a toothbrush, but I'm really curious about the fonction of this IC an I want to learn. Thank you
