If your faucet was manufactured before February 2009, the grounding clips may not be properly installed. Make sure they haven’t been bumped off with use and that they’re in the proper place and secured with tape. Also check for proper grounding. Note that grounding is not required on faucets with Touch₂O Technology manufactured after February 2009. If your faucet does not have a green ground wire, it may not require grounding.

The spout may be in electrical contact with the sink. Make sure the spout insulating components are in place.

Remember too that the faucet automatically shuts itself off after 4 minutes on kitchens and 1 minute on lavatories if there is no activity.

With Lav products it is required that the popup is changed to the supplied non conductive popup. Also ensure that spout sense wire and LED wire are not making intermittent contact with metal parts under the sink. If problem persists, adhere LED wire, battery wire, and spout sense wire to the back of the cabinet.
