Electric Toothbrush Diagnostics
Just about the only thing that goes wrong with an electric toothbrush is the body unit (the piece you hold that accommodates the brush - however the toothbrushes can be bought in a pack, check our website with make and model number for price and availability.)
Although the body contains rechargeable batteries, they are rarely replaceable,this is a complete replacement unit.
The charger (base) unit may also fail.
