If your touchless faucet won't shut off, it could be due to several reasons: Dirt or mineral build-up on the sensor, a problem with the faucet's solenoid valve, or a malfunctioning power source. First, clean the sensor thoroughly with a soft, damp cloth. If that doesn't work, check the solenoid valve for any blockages or damage. Finally, ensure the power source is functioning correctly, whether it’s replacing batteries or checking a wired connection. If the issue persists, it may be time to contact the manufacturer for further assistance.
