Any cracked solder joints can be repaired by reheating them with a soldering iron. You can find guides to opening your toothbrush on our website. Upon opening the toothbrush handle carefully inspect the PCB (Printed Circuit Board) and the solder connections to other parts of the toothbrush such as the motor, battery and charging coil. If you have dropped your electric toothbrush or knocked it onto the floor then an internal solder connection might have cracked causing a bad connection. There are two main causes for charging faults inside the toothbrush, either damaged components for example from being dropped or from water seeping inside, or a failed battery. Otherwise, continue below for help fixing the toothbrush itself. If you have now deduced that it is your charger at fault, head over to our Oral-B chargers page or Philips Sonicare chargers page to find a suitable replacement charger. You can also try their toothbrush on your charger. You can also try plugging the toothbrush charger into a different wall socket that is known to be working.Īssuming that the wall socket is live, if you have access to a spare charger via a friend, relative, colleague or neighbour then try putting your toothbrush on their charger. If it is, also check the wall socket by plugging a lamp or other electrical item into the wall socket to verify that the socket is live and switched on. If there is no warmth check that the charger is plugged in to the wall socket firmly.

If no lights come on when you put the brush on to charge, even after an hour on charge, has the charger and/or bottom of the toothbrush been getting slightly warm? In normal use the charger or toothbrush will be slightly warm to the touch after charging for a few hours. You can skip to the next section heading if the charging light is working normally. Firstly, is the charging light on your toothbrush lighting up or blinking as usual? If there is light activity when placing the brush on the charger then you can assume the charger is working and that the fault lies with the toothbrush itself – either with its internal circuitry or its battery.
