I have woodpecker DTE HD-7L ultrasonic scaler handpiece which is not working. The water does not spray and the LEDs do not light up not does it vibrate. I notices four electrical contacts on the rear as well as the water line. I am assuming two are for the lights what about the other two? What kind of mechanism is used inside the handpiece?
Hi, the other 2 wires are for ultrasonic transducer, it’s a device similar to a speaker, it doesn’t have any mechanical parts inside, it there’s no water no lights, then I assume the problem is in the main unit and not the hand piece

You are impressive.
any idea what the voltage to the transducer is? Total power to the hand piece? Thanks for sharing this repair
I’m not too sure I think it’s around 24 volts amd maybe couple of hundred mA

Can you repair handpiece scaler tip
Theoretically you can but they are potted in resin, so it would be really hard to do.
What is CLR ??
