Hallo,

Super-Anleitung. Kannst Du verraten, was für einen Motor man zur Austausch benötigt?

Spannung, Leistung, Umdrehungen, Maße, etc.?

Und vielleicht eine Bezugsquelle.

Danke Dir,

Kai

How do I know if the motor needs replacing? My battery seems fine. The toothbrush buzzes and I can hear it change modes when I push the mode button, but the head doesn’t swivel. Thanks

Die Spule unten muss nicht ab! Woher bekommst du eine Ersatz motor? Im Internet findet man Nichts?!
