My uv works but the toothbrush charger only makes sounds when I put the toothbrush handle on it. But the charging light never lights up and the toothbrush doesn't turn on.

My new diamond clean brush has been charging for well over 24hrs and is still flashing a green light (slowly) Is this normal? I was expecting a solid green light about six hours ago.

Mine still lights up but won't turn on and when it's on the charger the lights light up and u can hear it charging. It randomly turns on by itself but will not turn on when I try to turn it on. It just turns on and off by itself. What can b wrong with it?

Thanks in advance for any feedback you might be able to provide.
