Sloan EBF-11-A Solenoid Valve Module (For Battery Powered Faucets)

If you're experiencing audible beeps from your faucet's solenoid valve module after fresh batteries have been installed and the unit has completed its 30-second self-calibration cycle but no beeps are heard when something enters the faucet's sensor zone, the problem may be a defective solenoid valve module. Alternatively, if you hear beeps when a target is in the detection zone but you don't hear an audible click and the water doesn't start running, this could also indicate a defective module, which should then be replaced. Other possible causes of these problems that should also be checked are an improper fiber optic cable connection to the solenoid valve module or that the fiber optic cable itself is defective.
