I have the following toothbrush: Oral-B Braun Genius X Type 3771 The toothbrush can be fully charged, battery lights are working normally. It can be switched on, all indicator lights are working, pressure sensor light is working fine, timer light is also working. The problem only is that it just won’t spin/vibrate. I’ve replaced to a new toothbrush head, but still doesn’t work. No humming/sound from the body at all. I am willing to attempt to repair it by myself. My questions are: I’m suspecting motor problem inside, is this correct?Is it repairable?Is there a guide? Thanks for your time. Hope you’d help me out.
Hi, Is it humming but not spinning when you try to turn it on? If it is humming, check if you can you gently turn the spindle by hand to see if it moves or even if it starts to turn by itself (if the power is switched on) once you try to turn it. If so it may be that there is not enough power to initially start the motor rotating or the spindle is jammed somehow. If not you may have to find out why the motor is not getting any power. Couldn’t find a guide for your model but here’s a video that shows how to replace the batteries in a Genius 3765. Hopefully this is close enough to your model to be of some help. At least enough to open the toothbrush so that the motor action can be checked.
I found that toothpaste remnants can jam up the axle that sticks out of the body and goes inside the brushhead. Clean it up, and use pliers to move it the way it normally would (it swings about 30 degrees) This worked on mine. YMMV
hi, It is the second time I have the very same problem! Were you able to fix it?
