Question

Answer

Why doesn’t the Sonicare 

toothbrush work?

You may need to recharge the Sonicare. Charge the Sonicare for at 

least 24 hours.
The socket may not be live. The electricity supply to sockets in mirror 

cabinets over washbasins or shaver sockets in bathrooms may be cut 

off when the light is switched off.
You may need to reattach or replace the brush head.

Why do I feel a tickling sensation 

when I use the Sonicare?

You may experience a slight tickling/tingling sensation when you use 

Sonicare for the first time. As you become accustomed to brushing 

with the Sonicare, this sensation diminishes.

The brush head chatters against 

my teeth. What can I do about 

this?

To avoid this, keep the brush head properly oriented, with the bristles 

placed on the gumline at a slight angle.

Why does the toothbrush seem 

less powerful?

You may need to charge the Sonicare.

The Easy-start feature may be on. Deactivate the Easy-start feature 

(See chapter ‘Features’).
You may need to replace the brush head.

Why doesn’t the Personalised 

Brushing button work during 

brushing?

You may have selected a brushing routine. If this is the case, the 

Personalised Brushing button is not active (See chapter ‘Using the 

Sonicare’).

Why doesn’t the sanitiser 

light go on?

The socket may not be live. The electricity supply to sockets in mirror 

cabinets over washbasins or shaver sockets in bathrooms may be cut 

off when the light is switched off.
You may need to shut the sanitiser door.
You may need to replace the UV light bulb (see chapter 

‘Replacement’).

Why does the toothbrush seem 

to lose power during brushing?

You may be in the Max Care brushing routine. If this is the case, 

the routine alternates between the Clean and Massage modes 

throughout the 3-minute brushing cycle. The Clean and Massage 

modes have a different sound and brush movement.

Do I need a special charger if I 

travel with my Sonicare?

Travel tip: the travel charger, the deluxe charger and the sanitiser can 

be used at common worldwide voltages between 100-240V AC, at 

either 50 or 60Hz. All you need is a simple plug adapter.
