Solution

Make sure the socket is live when you recharge the appliance.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.
You may experience a slight tickling/tingling sensation when using the
Sonicare for the first time. As you become accustomed to brushing
with the Sonicare, this sensation will diminish.
The Sonicare should produce a gentle hum during operation.Tightening
the brush head nut can eliminate excessive rattling. If the rattling does
not stop, you may need to replace the brush head. Make sure you
remove the travel cap before switching the appliance on.
You can avoid this by keeping the brush head properly oriented, with
the brush head placed on the gumline at an angle of 45 degrees.
