Philips Sonicare not charging: causes and fixes

Quick checks

1. 1

   Check the socket works by plugging in something else, such as a phone charger in another room.

2. 2

   If you use a bathroom shaver socket, check its voltage switch is set correctly for the charger and that the socket is switched on.

3. 3

   Make sure the plug is pushed fully in.

4. 4

   Stand the handle upright on the charger, fully seated, with the head attached or removed as your manual shows.

5. 5

   Wait several minutes and look for the battery light.

Glass, stand and travel case chargers

Glass chargers on DiamondClean models work only when the glass sits on its base and the handle stands upright inside the glass. The glass must be the one designed for that base. If the handle leans, it may not charge.

Stand chargers need the handle placed squarely on the post. Turn it slightly until it sits flat.

USB travel cases need a suitable USB power source. Try the wall adaptor supplied, or a different USB adaptor, and check the cable. Some cases charge the handle only when the case itself has power.

Dirty contacts and residue

Toothpaste and limescale can build up on the base of the handle and the charger. Unplug the charger, wipe both with a damp cloth, dry them fully and try again. Do not use abrasive cleaners or poke anything into the charger.

Our guide on how to clean an electric toothbrush covers the handle, shaft and charger.

A completely flat battery

If the handle has been left unused for weeks or months, the battery may be deeply discharged. It can take some time on the charger before any light appears. Leave it charging for several hours before deciding it has failed.

If the light comes on but the brush runs only briefly, the battery may be worn. See electric toothbrush not holding charge.

Note:Do not open the handle or try to replace the battery yourself. If the handle is cracked, swollen or has been dropped in water, stop using it and contact Philips.

Are Sonicare chargers interchangeable?

Many Sonicare handles use inductive charging, and many chargers work across several models. But Philips does not promise that every charger works with every handle, and some newer models use different chargers or cases. Some models, such as Philips One by Sonicare, use a different power method entirely.

The safest route is to look up your handle's model number, usually starting with HX and printed on the handle or box, on the Philips website and buy a charger listed for it. Using a charger that is not listed may not work.

When to contact Philips

If you have tried a working socket, a clean handle and charger, several hours of charging and, ideally, a second compatible charger, the fault is likely in the handle or charger. Philips listings mention a 2-year limited warranty on many models, so check your purchase date and contact Philips support.
