The device has to be opened and partly disassembled. The battery has to be unsoldered from the logic board and can then be replaced. Just above the lid there is the induction coil, so don't pull too much, or it could get damaged! Take the screwdriver or the plastic opening tool and go under the ring at the top of the gummed area. Be careful not to damage the gum under the ring, as it assures that no water gets inside! Then pull the center of the black metal connection of the pressure sensor slightly upwards until the hook holding it to the sensor comes loose. Now you have to desolder the sensor connection and both the connections to the red led at the top. And keep the soldering time short and remove the soldering iron as soon as the solder has become liquid, so there is no overheating risk! Now the connections to the motor have to be desoldered to take the battery casing of. Cancel: I did not complete this guide. Badges: 4.

The bristles change color to let you know they are getting older, but they never get misshapen so they are just as good as when you started using them 3 moths prior.

Now you have to desolder the sensor connection and both the connections to the red led at the top. If water has got inside the brush and seized the motor then the best you can do is apply light oil to the bearing at each end of the motor and turn it by hand to free it up. For other toothbrush models and type numbers the battery replacement procedure is slightly different so please see our other guides to toothbrush battery replacement instead. Bad motor? And that maybe my old battery is fine! Bit concerned to clean my teeth with that now… :X. So how do I take the front apart so I can soak it in water or something as well as grease the motor shaft?

Remove metal ring at the top of the case with a flat screwdriver spudger, pick or any thin flat tool will do. While doing this be careful not to puncture the elastic rubber underneath.

I dis-assembled again, thinking perhaps that a motor lead might be off, but noticed that both the motor and the battery were warm, too warm if you ask me. Put the toothbrush back on its charger and push down on the handle to compress the spring inside the base. Maybe its because of the new battery so its stronger or i did something wrong and the tootbrush is so strong right now that you could clean rust off an boat?! Eligible for Return, Refund or Replacement within 30 days of receipt. Changed the battery and not confident that my soldering is good enough: the green light is flashing very fast, rather than slowly and regularly. AI-generated from the text of customer reviews.
