Reparatur bei schwacher Motorleistung

saved me from buying a new toothbrush, thanks!

Yup - worked for me too!

Just worked with my toothbrush, saved me a purchase, thanks muchly.

Thanks!! Saved me a lot of time and money! Keep up the great work!

Great guide. In step 5 I needed to pull the motor from the battery piece to open, not apply pressure.

Then I tried both credit card space and maximum space between motor and magnets, and vibrations with maximum space seem stronger.

Definitely a design flaw. Or maybe even intentional… who knows.

Just replaced the screw of the head and fastened that and fixed the magnet spacing. It does seem to work again, but I don’t know for how long. THanks

What is step 6?

Great guide. Thanks :))

What is the reaseon in step 6?

Perfect solution. Thank you!!!

What is the reaseon in step 6?

Top! Funktioniert alles wieder.

Can somebody give me some tips about step 5 please? I’m scared I will break the logic board if I apply too much pressure. How is it support to open?

Took a little doing but my magnet was totally tight to the electromagnets. Loosened the screws and put the gap back. I used Permatex threadlocker blue on the screws and put it back together. Works perfect now. Thank you so much for the help!!!!

Great! My brush was out of warranty so no help from Phillips, though they admitted that “in almost all cases where people had any issue with their brush, this exact description of technical problem matched their issue “. The problem I described was precisely that described above.

With the help of this guide my brush is working again ! ! !

I loosened the two screws and moved the magnet down, but there is still on gap. I don’t understand how to move the top magnet/driver up to create a gap. They are still touching.

definitely saved me some bucks :) Thanks a lot! Great solution.

Fixed my problem with my toothbrush and saved me a lot of money. Thank you!!

@Z A The silver magnet and the red electromagnet can be separated with fingernails. The permanent silver magnet will tend to hold them together, but once separated the corner of a credit card can be used to keep the correct amount of distance until the two screws are tightened.

@Anja The logic board in pegged to the metal chassis by two small pegs on the underside of the black plastic holder underneath the logic board. They fit in a tee slot and shifting the board downward, when the brush is in the usual upright position, will free them. Check the comments at step 5.

This repair procedure fixed my Sonicare, which had stopped brushing and wasn’t making a vibrating sound when pressure was applied to the brush head in certain directions. Most videos on YouTube show how to tighten what appears to be the Philips screw near the brush head shown in the black oval in Step 6, but that was OK in my unit. Like the OP I’m not sure why the electromagnet had shifted - the unit had not been dropped and the screws were fairly tight. Maybe the vibration gradually shifted the electromagnet.

For me the hardest part was getting the end cap out. It took a fair amount of patience and persistence, using both the pliers and a small flat blade screwdriver.

Thanks for the helpful tutorial.

I’m at step 4 but my screw won’t get loose? Any help?

My brush has been weak ever since I bought it. So it either came from the factory like this or maybe was dropped or roughly handled during shipping. Following these instructions fixed it. The force to pull the magnets together was quite strong so I used a toothpick as a spacer to hold them apart. Kind of a poor design to let the magnets ever get close enough to touch if you ask me.

This fixed one of my kid’s brushes, though step 5 was by far the hardest part, even after reading the comments. I’m still not sure how I finally got the metal part off the black plastic part without breaking something. I used the maximum gap for the magnet portion and it matched a new one I had just bought, strength-wise.

I have few sonicare toothbrushes and all was broken by water got inside. I replace batteries and now all they works, but they are less powerfull then toothbrush with new motor. I try many gaps beetwen magnet and coil, but ewen if magnet vibrate strong, the head is moving weak. The triangle shaft inside is not broken, but it looks like it loosing power some where there. Any ideas? All of this had water inside and have some corision, maybe this is the reason? I also deasambly mechanism which connets magnet and head and its looks like it shouldnt be frilage to water. So i have no idea why it loose power and doesnt work.

Thanks. You saved my toothbrush. After accidently dropind it, the coil moved to close to the magnet.

Thanks a lot! All works fine now!

Spot on — fixed my Sonicare right up — many thanks!

If step 5 is confusing or difficult (as it was for me), please check the comment that I left for that step (above, next to the step description — click on the number of comments to see them. Once I figured how to disconnect the black plastic part from the metal part, everything else was easy.

top battery terminal can be corroded as well, but the bottom of the battery is soldered on, so pull the top away and clean the top of the battery and the contact if you can. fixed mine which was just still stuttering when i pressed the power button even with the right gap.

In Step 5, the logic board felt like it was going to break if I applied pressure. So, I didn’t open that part and ignored the second screw. Instead I followed the advice from another site and used a little flat head and pried in between the magnet and the electromagnet and gently twisted it to give a gap, while holding apart i used my other hand to tighten the screw again.  Works fine now.

This fixed the problem. Great guide.

Thanks for this. Worked a charm… and not what I was expecting!

I do think step 5 could be updated to be clearly about “push back”… although, having managed, I appreciate the arrow is correct…

hay ho.

Nice one, thank you. These toothbrushes seem so sensitive to being dropped, even only maybe 1 foot/ 30cm into the bathroom sink, and then they lose full power transfer to the brush head and make horrible noise! Now that I re-opened the gap, it sounds quiet and works as it should! :-)

Thank you very much for this!!! Yes I agree with others that for step 5, there are two plastic tabs that prevent the plastic part from sliding too far. Prying from two sides with a flathead screwdriver to undo the taps will make sliding the plastic part from metal frame a lot easier. I tired both max spacing and one credit card method, I couldn’t feel a significant difference. However I feel like it does vibrate stronger after I’ve fixed it.

Die Beschreibung in der Anleitung ist hervorragend. Reparatur war ein voller Erfolg —> fehlender Abstand zwischen Magnet und Antriebsteil war das Problem.

I knew it was something fixable because it wasn’t a charging issue or brush head. One day it didn’t turn on when I pushed the button and had to push it a couple of times. When it did it was really weak like I had it on the lowest setting even though it wasn’t. Hated to think about throwing it out because I have a Flexcare Platinum with the stand and UV sanitizer, not a cheaper model by any means. THANK YOU!! Can’t say that enough. All I did was pull up and outwards gently and it pulled away from the circuit board. DON’T pull hard otherwise you might rip off one or both of the red wires that attach it to the board. The wires are flexible enough to bend forward so you can get at that final screw to loosen the magnet enough to slide it down away from the upper portion and put the correct gap in.

In my case, I found that setting the air gap to 0.010” (0.25 mm) gave the best result.

Setting the magnets too far apart reduces the performance of the vibrating motor.

I loosed the two screws and used a pocket knife to make more room between the megnets and now it’s working fine. Thanks

the screw tightening doesn’t hold it apart, my magnets spring back down with force. maybe there is a spring broken above :/

Thank you, worked on the 5630 as well!

I noticed that in your first step u pressure the brush housing from different sides, than the guide which u recommend later does. I tried both and i figured it is much easier to pressure it 90 degrees rotated. With yout method it took some time, but with the other it popped right out.

The guide is pretty well written and safed me from buying a new brush.

Thank You so much! I fixed my Sonicare HX8910 HealthyWhite+ Magnets touched the metal part. If I can tell you it is easier to remove the rubber part with the spring just behind the magnets, it can be done relatively easily, and thanks to that it is a lot easier to remove the magnets - I am a woman and I did not have the strength to pull it so I looked for something easier :)

Great guide, fixed my Sonicare after it had been dropped the vibration wasn’t quite right. The 2 magnets were hard up against each other. Step 5 was the trickiest, click into the comments and read Rick Palmers note about how to separate the plastic and metal bits. The other tricky bit was separating the 2 magnets, they were pretty firmly stuck but there was a definite click when they did separate (used a finger nail on either side). Left a credit cards width between them and it fixed the problem.

I did this and it worked great! A couple suggestions:

—Use a credit card to create the right amount of space between the permanent and electro magnets. When I opened the toothbrush, my magnets were stuck together. The first time I repositioned them to the maximum distance. The result was a much stronger vibration than when they were stuck together, but after reading the comments, I redid it with a credit card and now it feels like brand new.

—In Step 5, you need to separate the metal part that holds the electromagnet from the plastic part that holds the circuit board. This is tricky. I suggest removing the spring located just below the parts first, then move the metal part up and down until it releases.

—After putting it back together, I’m not sure the seal at the bottom is water tight anymore. Not sure how to correct that other than trying not to let it get too wet — avoid leaving it in standing water.

The same opening principle applies to the HX992B model. The cap will not pop out because it is help in place by a rubber ring. But with the pressure applied as above and prying with small flathead screwdrivers i was able to get it out. Thanks.

Thank you so much for this guide. I followed this to fix my Diamond Clean HX9340 after I dropped it, saving me $200. Taking the cap off was the most difficult for me, once that was out, wiggling and pushing down while using one screwdriver to loosen the plastic base on one side made it easy to get the assembly out. I used a screwdriver to pry the magnet from the metal and stuck a toothpick in between before tightening the screws.

This saved me from buying a new one. Thank you so much.

Did anyone of you have trouble sealing the bottom cover back on the toothbrush after you were done with the repair? I am concerned that I will end with a gap where water could seep in.

Vielen Dank. Hat wunderbar funktioniert. Danke.

Worked for me, awesome. Not sure how long it will last.

Thank you!! Works like a charm now. One thing that happened, when I separated the circuit board, a little black silicon triangle fell out and I still have no idea where it belongs…. Oh well!

Less gap more power in the brush. I think .5mm should be sufficient.
