The induction charging coil allows the device to receive power from the supplied charging base. It will need to be replaced if it is damaged by use or by external conditions. This guide describes how to replace the induction charging coil. Some steps in this procedure require desoldering connections. For a review of soldering techniques, check out this How to Solder Guide.

    • Use the charging station to remove the a small plastic plug from the end of the toothbrush by inserting the charging station into the end insert and twisting counter-clockwise by 90 degrees.

    • Remove the end cap from the bottom of the toothbrush by prying it off with a spudger.

    • Use a spudger to loosen the two plastic tabs next to the induction coil that secure the internal assembly to the frame.

    • Push on the rotating head in order to pop the assembly out of the black plastic casing.

    • You can also use a spudger to leverage the assembly out, but this may break the copper wire connected to the induction coil, so be careful.

    You need to release the induction coil’s plastic clips before you try to slide it out! This is a key missing step.

    I agree with Matthew. You must insert a spudger and release the plastic clips while pressing down on the rotating head. I held the rotating head with a pair of pliars and then released the plastic clips and it popped right out.

    Brian Davis -

    i third that, this needs to be added ASAP, you have no chance of getting it out without unclicking those two latches that lock the inner assembly to the outer casing.

    • Unwrap the ends of the wires from the white plastic pegs using a pair of tweezers.

    • Each wire end is wrapped around the peg 3-4 times.

    Unnecessary step for battery replacement! The electrode of the battery is solely the single solder point in the middle and the battery comes out just as well if you just leave the coil. If all you want is to replace the battery. just leave the coil, It’s fiddly and risky to break the wire and more work, only disadvantages. Good efforts!

    Achtung dieser Schritt ist für den reinen Akkutausch unnötig und quasi falsch! Die Spule kann verbleiben, der Akku ist einzig die einzelne mittige Lötstelle!

    • Melt the solder at the two pads on either side of the top of the motherboard. This will require a high heat soldering iron. Remove the wire from the solder pads using tweezers once the solder melts.

    • Remove the induction coil by pulling the plastic tabs out of their keepers.

    • A spudger can be used to remove the plastic tabs from their keepers if neccessary.

bonjour, ou puis je trouver une nouvelle bobine d’induction ou puis je remplacer simplement le fil de cuivre

Geoffrey Sacré - crwdns2853112:0crwdne2853112:0

juste une précision pour sortir l’intérieur de la brosse du manche il faut appuyez sur les deux pattes plastique en bas près de la boucle d’induction

on voit une des pattes a l’étape 5
