Oral B Series IO9 Teardown (How to open up)

[@kilovolt2494]

Thank you for the video a lot, and big thank to Braun engineers whoever they are for not gluing this thing shut or not using any adhesives like smartphones have nowadays. I just ordered io9 from Amazon and since battery is a consumable in any electronics, I was wondering what it takes to replace a battery on this one. Now I feel way more confident about that!

[@jadoei13]

Thanks for the video, I must say that putting it back together was a bit more challenging that I had hoped for and the seal might not be quite the same anymore. Defenitly wouldn't do this out of curiousity on a new brush again. The seal at the bottom of the brush is easy enough but the one at the top has to be sqeezed back under the metal ring. Once you've gently pushed the housing back over the assembly (without putting unnecesary force on the charging coils at the bottom of it) the seal is sitting on top of the metal ring. To make it look like new again you need to find a way to push the seal down and under the metal ring and then back up into it. I ended up using the knife from my pocket knife (keep the cutting surface away from the seal) as it was the only thing thin and strong enough I could find. Place the brush flat on the table, and place the knife between the metal ring and seal, again making sure the knife can't cut the seal. This should guide the seal without damaging it, and using a slightly wider object like a credit card to push the seal towards the middle of the handle. Once you've got it started you can slowly work your way around the handle and afterwards you can gently push the seal up into the ring. I ended up using my nails but just be gentle with sharp objects, you don't want to damage the seal too much. Keep doing that all the way around till it won't go any further (you can probably see the slight ring on the seal from where the metal ring used to end).

My battery is also useless. It says it's fully charged and then will suddenly die. It's a nightmare. Seems like this model has tonnes of problems. I'll buy a new battery and see how it goes. Thanks for the video. Ps, when I opened it the ceramic ring at the bottom was broken. I don't know if it was always broken or it broke while opening it...

thank you very much for the information, it helps me a lat 😀

[@---tq2xg]

couldn't get that bottom piece off even using maximum force, factory reset still kind of works (holding down both buttons for a while), going to try a few more times to get it off, but feel ready to order something cheaper this time around like the io3 perhaps given these kind of issues

[@voyagergaming1812]

Hmm, I wonder if they potentially changed the bottom design. I've seen a couple of new comments with this same issue. You were turning it counterclockwise right?

[@TheColdest247]

Man I wish I had seen this video first. There's a video that when the guy turns it counterclockwise it makes a clicking noise and then comes off. I couldn't get mines to do that so I used a tool that's scratched my brush a little bit on the bottom but now I realized I did feel it loosen a little bit and I didn't realize that's all I had to do was pull the bottom off. Oh well I'm not going to cry over spilled milk I did replace the battery. Now I'll have to see if it holds a charge.

[@gabrielambriz]

I recently bought this toothbrush, I am a bit concerned that you mentioned and showed that the motors are corroded on your brush after such a short amount of time(the brush is supposed to last anywhere from (2-5 years), could you give a guess why that corrosion took place? Is there anything that blocks the top that is normally exposed when the toothbrush is put together from water tricking down to the motors because that would be my guess for the corrosion. And did you put the battery back after removing it and was your "turning on and off by itself" problem solved? Anyways sorry for the long comment but thanks!

[@voyagergaming1812]

Hey! There is a rubber gasket at the top that should prevent all water from getting inside although even to this day I don't know how it happened. When I had put it back together it was still turning itself on and off so I ultimately had to RMA the unit; the replacement brush has had no issues thus far but I'm also extra careful about drying off the brush completely before putting it back into the travel case.

[@nami1540]

@@voyagergaming1812 Thanks for this good content. There is a small hole at the back, wich actually goes through. The water might come from that. It is there do prevent an explosion from a malfunctioning battery. My next guess then would also be, that it came from the top. My previous Oral-B brush was the 6000 smart, which actually still works. I did not take good care of it and didn't even disassemble it after each use. This will inevitably lead to dirt and mold buildup and probably some leakage inside the brush. It started smelling and the white plastic turned yellowish over the last 8 years I had it (I love the reliability, though). I really recommend and try myself to follow the cleaning instruction from the manual this time: Disassembly and rinse of both components after use + fully drying them before putting them back together. Nock the hand-piece upside down on a towel as well, as a lot of water will be trapped in the top mechanism.

[@zapatero-photo5597]

I opened the toothbrush to check the battery type to order a replace battery. When putting it back in the housing, unfortunately I didn't put the silver ring properly on the rubber seal. I used it 2 times and the display stopped working. There's a tiny bit of dry toothpaste visible on the side of the motherboard below the screen. Is there any chance to repair it without replace the screen or the whole motherboard?

[@paolap.7369]

Thanks so much for this ! Can you suggest a new battery for it ?

[@francoisg9154]

A big thank you for your video which allowed me to see the type of battery and wonder if an AA battery would be compatible? Un grand merci pour ta vidéo qui m'a permis de voir le type de batterie et de me demander si une pile AA serait compatible ?

[@voyagergaming1812]

Glad the video helped you out. AA is certainly compatible, although just keep in mind that the stock battery Oral-B uses is rated for 3.7v while most generic AA batteries brands are only 1.2v-1.5v. With this being said If you type in 14500 battery into Amazon you'll actually find a good amount that range from 3.6v-3.7v with a much larger mAh capacity which, theoretically, should work completely fine - just be carful about recharging non-rechargable batts as they could leak/explode; Keep us updated if you do end up making the swap!

i replaced my battery but when resealing it, do you have to twist the bottom cap clockwise to seal it? i tried that but the tool kept slipping away and im not sure if it's properly sealed now. also when i put the brush on there's a gap at the bottom of the brush now

Sounds like it's not sealed properly - all you have to do is apply a good amount of force and twist it clockwise for it to reseal!

It uses a Sanyo 3.7V, 740 mhA Battery - all you'll need to get is a 14500 rechargeable battery; there are a ton of options on amazon. You could also get a non-rechargable battery if you plan on just swapping them out, but you just have to make sure to never charge it as they will most likely explode/leak. Hope this helps!

I know this is a late response but this is great to hear! The white stuff you're seeing is corrosion. Pour a shot glass of 99% isopropyl alcohol over the board and lightly scrub it with a soft bristle toothbrush.

[@eidinbateman]

Hey you mentioned in one of your comment that you got a new one. Has that one lasted so far or did u have the same issue?

[@voyagergaming1812]

Hey Eidin! New one is still going strong, battery doesn't last as long as it use to though so after every use I just put it right onto the charger now; If the battery issue gets any worse I'm going to post a video guide replacing it with a higher capacity battery. I think this will be useful because you could then hot-swap batteries completely skipping over having to wait for it to re-charge as I've had it happen a couple of times now were it's died mid-brush.

[@eidinbateman]

@@voyagergaming1812 Thank you. Quite worrying that such an expensive device shows so much corrosion after 4-5 months. The Philips Sonicare devices seem to be badly designed as well ….

Hi, I have only owned this toothbrush for a week and all of a sudden I felt that daily clean mode has become more powerful than before. Not sure what happened. I have dropped the handle twice onto to floor and now am concerned that I have damaged the motor. But this did not happen immediately after the drop. And the app sometimes stops tracking and said brushing time was too short while the brush was still working - maybe some bluetooth connection issue. I am more concerned about the first one. Any ideas?

[@voyagergaming1812]

Hey Tommy, I'm sorry to hear this. Nothing was cut from the video and I'm not sure what the metal ring is you're talking about. This was filmed 3 years ago and this is the first time hearing of this. Looking back at some of the more recent comments now, there have been a couple stating that they can't get the bottom cap off, which makes me believe they could have possibly changed the design of the housing; But this is the first comment I've seen regarding my guide breaking an o-ring seal. What you saw in the video was the proper way of disassembling the brush, I also had a sample size of three. Feel free to send me an email as I'd love to look further into this!
