Repair of Braun Oral-B Genius X. Lights up, but no vibrations. 

Before you buy a new fuse, just apply some pressure on the fuse with a small screw driver, it pushes in and works again. It worked for me at least. If doesnt help, just remove the fuse and connect 2 points without fuse, it will work just fine.

If you’re going to be applying pressure to the fuse, remember to have the brush turned ON while doing so. This is what made my brush work again!

Thanks!! I was so mad that it stopped working 2 months after the end of warranty... Found your video and just had to press the fuse!

Thank you to the people who suggested pressing on the fuse because it worked so well I actually scared me! I’m now going to try the same thing on my daughter’s toothbrush Thank you Let’s Fix It Garage for showing so clearly how to open up the toothbrush casing

So here’s the situation: I’m in Brazil and this is a really expensive gadget to buy. If it weren’t for your video AND the comments here on pressing on the PP fuse, I’d really have to replace it with a cheaper option. Thanks so much, my friend!!!!!

Thank you very much Sir for this video you have uploaded, its very helpful and practically applicable to my Oral B Genius X toothbrush. I've only used my unit for just a year when i've suddenly experienced this malfunction in my unit, i bought it brand new and yet i experienced this unlikely trouble but thank God, your here to save my day and because you've uploaded a video like this - i'd been saved to pay expensive repairs from any technicians.

@LetsFixItGarage Massive thank you for posting!! This was incredibly helpful ❤

Absolutely EPIC! had this problem last night, similar that I thought it would be the battery. Popped it open, tried to press the fuse but it wouldnt work. Pressed it on and then pressed the fuse down and now its back to its original self. Thanks a ton for the video

Thank you for sharing this information. I have a feeling this is a common issue for all these similar models. My first Genius x 10000 died the same way but it was under warranty so they gave me a replacement. Now less than a year later the replacement failed the same way. I was able to revive my toothbrush with your video so thanks again.

Thanks! My toothbrush was replaced 3 times during 1.5 years . The warranty lasted for 2 years and 1 month after it just stopped working again. I have looked on youtube for some adviced and found this one. As I have no experience with electronics I just used a screwdriver to press on the fuse and it just magically started to work. Now lets see how much it will last.

Followed the procedure, pressed down on the fuse and it all works fine! Thank you very much!

Pressing on the fuse worked for me! We'll see how long it lasts... Thank you for your video!

Thank you so much ☺️ I just pressed the fuse with a screwdriver, and everything thing was OK again 😁

Thanks again man. Saved some money with your video ❤

Thank you so much! Me and my dad took it apart and he said the solder was really bad on a few of the points. He just reheated the solder on the fuse I think… just a bad connection. It’s lasted for 2 weeks absolutely fine so far! Thanks so much for your video!

Hi Let it fix garage. This video was very helpful. I‘m not the expert to solder. The greatest challenge was to find someone to solder the fuse. The electritian will just solder it out and just want to bridge it. I hope it will be alright.

Thanks - following this guide I fixed my toothbrush!

Thanks for the video 🙂 Tried the first fix with pressing on the fuse with the tip of my nail. Works so far 👍

Thank you sir you saved me. I just use a screwdriver to put some pressure on the fuse and it is working again!! 🤞🤞🤞

Thanks a lot for the very informative video ! you are the best !

Your Video is awesome! Exactly the Problem i was having and additional info in comments (pressing down the fuse and resetting the microcontroller helped lots). I now have a working toothbrush again for 0€. Thanks all!!!

Thanks a lot, I desoldered the fuse and instead short-circuited the two pads and now it's working again 😁. As you point out in some comments adding a new fuse is better but I guess the risks involved are fairly low

Amazing! pressing down reasonably hard with a blunt object on the fuse also fixed mine!

Thank you - pressing "pp" worked for me.

Helpful video, thanks!

Thank you very much for the video. That was very helpful !!!

Thank! I just fixed mine! Got repaired twice within the warranty and now I can do it myself.

Thanks for the video. I followed first the one of the comment below , pressing the fuse worked!

Thanks for the video, I was able to solve the problem just by applying some pressure on the fuse.

Thank you, the opening works great ;)

Thank you I did all of what you mentioned except as other users have mentions I applied pressure to the fuse box named' pp' hard enough until the brush came back to life, saved me £80

Thanks, just fixed my Genius 20,000, instead of fuse I placed one thread of multithread wire and sorted the fuse. (in any case, I bought the new io10 🙂)

Thanks for the video! Managed to get one with leds lighting up and 1 sec of motor action working by compressing the PP fuse. After one use, the whole brush died, no action at all. The microcontroller (TI CC2640) can be reset by grounding pin no. 35. I used a 1k resistor to ground it on the motor ground. Brush woke up instantly. Now testing to see whether it works long-term. I suspect that something is failing on the board. This brush has been abused a bit and it has a crack on the body, but no obvious liquid damage is visible.

Welp! Here I am. Same problem as everybody else. Watched your video, ordered the fuses and then I started to read all of the comments. I tried the pressure thing on the fuse and that didn't work and then I kept reading. I too heated up the fuse a little bit here and there just for the heck of it. Once I let it cool down I tested it and it works great again. I know you have responded that it probably isn't a good fix but I figured what the heck. We are going to run a test. Today is December 19th 2022. I will return here and comment when or if it goes bad again before I mess with a new fuse. Thanks for the video

Thanks! For me, resoldering the fuse did the trick.

I followed the video and I just had the soldering iron touched the pp element on both ends without removing them. Guess what? It is working again. Thanks for the video!

Danke! You saved my vacation!

thanks for sharing this information.

Everyone who bypassed the fuse have there been any issues? Blown up toothbrush, bathroom, house, city? I just bypassed with blob of solder. I dont have the skill or good enough equipment to solder a new fuse so hoping to leave it. Thanks for the vid got me working again.

Thank you mine is working now

Nice video! Do you know if they changed this style within the newer IO model? I have a genius x which had this issue, I got it fixed under warranty now the same issue happens. For me I might just get the newer model

Thank you so much!

My brush would run for a second or two, slow down and stop. I found that polyfuse marked PP was dropping about 3 volts in the stopped condition. PP is a Bourns MF-PSML300/6-2 0805 rated 3A. Bypass PP with a multimeter set to DC current, the brush runs and the meter reads 0.5A so my fuse must be faulty. I bridged the fuse with solder and it works now.

Thank you so much for this video. I have one question I have same toothbrush and when I opened it I saw lots of rust soecialy on the motor part. How can I clean them? Thanks!

Thank you for the video! It seems we all have the same issue. I started to follow your tutorial but having trouble removing the top ring. What tool did you use? TIA.

Hello - Thanks very helpful. I have the same symptoms as you say while during diagnosis with multimeter suddenly lights turned off and I am no longer able to turn it on. Do you have idea what could be the reason- is it possible that it is still the same fuse only? I feel like I created some short circuit or so…

Which 2a fuse did you use. Theres a few different ones available like 1808/1206 etc. cheers

Really appreciated your video here. Same symptoms for me, toothbrush might rotate for 2-3 seconds but would stop, then nothing for several minutes or even wait overnight to get any life again. In my case I applied a bit of pressure to the 'PP' fuse to see if there was any physical connection problem and sure enough, this 'fixed' my problem. So I believe I had a cold solder joint. And with the high vibration of these motors you might expect this to happen with some units. I don't have smd tip or tweezers for my soldering station, but I used my smallest tip and added just a small amount of fresh solder to the fuse pads. Seems to be working for me for a couple days so far. Thanks again.

Thanks, I ordered some fuses but they ended up not fitting, but when I tested the old fuse with a multimeter it showed continuity, so I soldered it back on and it's working now, for how long I don't know, but for now it does.

Thank you!

you are our hero

Do you know where you can find a parts store for the tooth brushes? I am looking for plastic outer shell case. Do you know where to find them.?

Cześć. Mam szczoteczkę oral b pro 2 2500. Po włączeniu jest mały dźwięk. Nic nie świeci, silnik nie kręci. Bateria jest dobra. Jakis pomysł? Proszę o pomoc

I Pressed the fuse and worked it! Thanks for sharing your knowledge.

thank you so much, you saved me 200$!, for now I just pushed the fuse down and it worked! any idea where we could find a remplacement part?

Hello, I am trying to find a document/source/information indicating the meaning of colour "main" LED which has turned from white to blue+green (from outside looking, no dismantling) recently and these last couple randomly days into full blue. I hold a genius 9000 from 3 years now and it behaves like that recently (3months approx). I also observed once I started it, it was stopping by itself despite battery indicator was showing not empty. Furthermore, if you apply too much pressure during brushing, main LED should lights which I didn't observe since a while... I had previous Oral B generation which I do not remember the category. No sign of battery charging/duration loss/decreasing in power/rotation speed or even noise except when battery goes low charge ( I never wait a full discharge for recharging). Oral are quite noisy compared competitors ;) From full charge (couple hours upon charging voltage so mainly during night/sleeping [I am changing world region with working area => 110-240Vac], I do not observe any battery life "reduction". My first query would the battery's spec. I read through few website indication of 1.2V but once opened with elements in place (nothing removed), I measured 3,49Vdc approx. Once board/mechanism removed from holder, my battery looks similar the one on this video, same colour. Sharing troubleshooting experience just now ; ) . Prior looking that video, I was trying to investigate more and possibly replace the battery, I bought one of 1,2Vdc. There was some rusted moisture near "teeth wheels" behind the motor. It may have affected the board components and produced unexpected behaviour. I didn't succeed (very limited hand welder or too old) to remove the battery for better inspection but after this, I noticed by pressing the starting button, the toothbrush was keeping in operation without interruption as written above. It might happened during welding I "remade" the connection battery to board on better connection than before. At the end, old battery still in place. However, the 2 leds (blue and green) remain ON during operation phase. I am very curious of the colour designation. I remember at first bought, main LED (from outside looking) was white. Any suggestion/idea or eve from "Vilnius". Would great, thank you.

Hi, thanks for the video! Me and my Dad both bought toothbrushes at the same time and I’m about to move out and mine broke. 😂 The pressure “fix” worked for me thankfully. Could using this fuse until failure cause any further damage? And how would I know the fuse has failed completely? Would it just not work? Sorry for the questions lol

Hello! I just found my Oral B Genius X wouldn’t charge and turn on! I think it is because of the damaged electrode between the battery and the mainboard. Do you have any ideas on how to fix it? Thank you very much!

thanks! never bothered to use the tester on my sonic-fx until this video. turns out it's only a power button problem! it turns on while the probes shorts the contacts. however, I have no soldering skill and I already bought a new toothbrush, good thing its only $7. I will probably parallel the power button to the mode button and see what happens.

Hi, can I also use an 1 A fuse? Thanks for the video. I will try to repair later.

I broke the seal that’s at the top of the plastic that lights up when using a clamp to unseal it. Needed minimal pressure. Is there somewhere I can get a replacement?

Good video. Thanks for posting. However my toothbrush will start and run for 5 seconds or less. It has a full charge. So what do you think?

7:47 what is the voltage after the second smaller fuse? Mine shows a drop to about 1.3 volt after the smaller fuse from the ca 4 volt battery-voltage after the bigger fuse. (I have one that is dead, neither lamps nor any switch working but that the motor and its different modes are startable through an easy touch over a resistor in the vicinity of the fuse you changed)

I’ve tried for an hour to get the top cap off and have cracked it along the way. I’ve tried all sorts to get it off (even heating it). Any recommendations for getting it off?

I have the same problem with Oral-B Genius X Limited, should I buy the same piece of fuse that I used with the same power or do I need a different power

Is a 0805 fuse with 1A good to use too? If yess or no what is the difference with a 2A fuse?

Thanks a lot from me too ❤

Applied soldering iron to fuse, brush working now. Added some solder to bridge fuse. Will see what happens, hope solder does not come off inside

Thanks for the movie. Could you please add the correct name of the fuse? the second ali link is down and the first one does not have a 2A anymore.

Hello, yesterday I repaired two such brushes, there was no need to replace the fuses, the solder joints were cold, I just had to re-solder them. Everything worked until I put the brush back together... now nothing, dark, dead. Battery charged, no lights, no charging. What could have happened? Regards

Hi I find fuse 0603 3A with 32V is that ok? or is the V too high?

I have the same model, same problem and no warranty! Can you please explain what were the materials you used to attach the new fuse?

Mine keeps cutting out, fully charged sometimes it will start full power then just randomly cut out, keeps doing it. Do you think this is same issue or different?

can you also share the solder model that you've used in this video? :) thank you

Ironically the fancier more expensive models seem to have more issues. My $20 model from 15 years ago has been working perfectly since I got it

Hi I have the exact same problem. Connected both ends with a pliers and the motor started working. I took out the fuse before my new fuse arrived. made a bridge just to see if it worked but now i can't get any lights on the brush? maybe I damaged something while taking the fuse? What is the next component after the fuse? I can see 4 volts reach the component labbeled E (i asusme it is next after the fuse) any tips for trying to find out might be wrong? Thank you

what is the specific name of the 2 amp fuse please. I cannot find your replacement part online

If my toothbrush vibrates a couple of seconds 1-2, could it be the same issue? thanks!

Please provide a link to purchase the part for the repair.

I just tried the "pressure fix" meaning pressing on the fuse with my tweesers, and it is now working again. I will try to report back if it stops working again. I am not sure if this a problem with seating though it should be soldered in .. or if there is a reset. I noticed that some of the fuses that Let's Fixit listed were described as resettable with pressure.

Hi! I'm about to order these fuses on aliexpress. What AMP should I order? Thanks.

Hello, I changed the fuse... but I think I touched something by mistake on the board and now it doesn't start at all, no LED lights up. I have this problem with 2 brushes. Can you help me please? Thanks and best regards,

Thanks!

hi, can you give me other similar fuses to use pls? Because they are finished. And thanks for this beautiful video!

Valeu!

Danke!

Can you make a video about speeding up this brush?

It is very meaningful sharing, and I am aware Oral B has the general problem on Genius X model. May I know the part number of the fuse, and I can look for extra help from electric store? appreciate

Thanks for the video! Helped to save mine toothbrush. Link to soldering iron is dead. Could you post name or photo please of soldering iron you use?

A great tutorial, but my situation is strange - I replaced this fuse and after 3 work cycles it burns up again. I also replaced the neighboring one and nothing.

Привет друг. Не подскажешь что делать, была такая же проблема, но перед заменой я отпаял мотор, после этого плата перестала включаться вообще, я припаял обратно, но включатся она и не начала. Когда ставлю на зарядку, верхний светодиод моргает на миллисекунду, и гаснет, потом через секунду опять мигает. На этом все. Питание на плату приходит. UPD: а не, я спалил мотор, замкнул + и - 😢

Are you sure the PP marked SMD component is a fuse ? I have serious doubts. I believe it to be a zenerdiode. Thats why you measure a small resistance when measuring it. I would not recommend to replace the zener diode by a fuse.

Аналогичная проблема. Сейчас попробую заменить. Надеюсь поможет

Mine doesn’t have any fuse market pp. it has a 2L00 instead. it also lights up and motor doesn’t work. Its the black one with bluetooth

Hey everyone! Thank you very much for this Video! I have exactly the same Problem as in this Video... Can someone explain it in German to me? I dont know what He ist looking with his "Sticks"..i dont know what He is fixing.. Thanks a Lot!

What is the amperage of the PP fuse? I want to change it

I’m having trouble with mine. All the lights come on but motor doesn’t turn the brush head. How do I find someone to fix this for me as I don’t have the fuses or tools to fix it.

These self-resetting fuses are named PPTC or PTC. Does anyone know which type it is? Voltage, Current and resetting time?

Which of them is works? 1206 2A or 0603 1A

i have the same brush, it starts for 3 secs and stops until you switch it off and start again and the same happens. pressing on the fuse helped and it started working, i guess connection fails because of vibrations. tried to fix it with crazy glue ..will see haha
