Thank you for your question, and I am sorry to hear that you are experiencing an issue with your Delta faucet. We recommend to reset the LED light wire and battery pack. To do this, disconnect the LED light wire from the solenoid. Disconnect the battery pack. Wait a full minute. While you are waiting a full minute, you can check batteries and see if they are in good condition, even try new batteries. Make sure they're all in the correct direction and tightly secured in the battery pack. After a full minute, reconnect the LED light wire into the solenoid and then reconnect the battery pack. Wait another full minute. After the full minute, you can then check your faucet and see if you are getting a blue light, if not please contact our Delta Customer Service line at (800)345-3358. We are available Monday-Friday, 7am-7pm, CST and Saturday, 8am-5pm, CST. You may also email at email@example.com. .
