This guide will show you how to replace the motor on your Philips Sonicare DiamondClean electric toothbrush.

The motor will need to be desoldered from the circuit board in order to be removed, so be sure to check out our How to Solder and Desolder Connections guide if you are unfamiliar with best practices!
