Before you begin to troubleshoot the touchless faucets, check to make sure there are no clogs or loose connections in the standard plumbing equipment. If everything is okay, then the problem could be caused by the automatic faucet's electronic parts, like solenoid valves, sensors, and even batteries.
Worn-out solenoid valve
The solenoid valve works with the touch sensor to turn the faucet on and off. If the valve is worn down, it will not push or pull as effectively as it should, and may need to be reset or replaced. You can find the solenoid valve underneath the sink, attached to the battery pack.

Just remove the battery from the pack; wait 30 seconds before replacing it. This will reset your faucet.
Myth #1: Touchless faucets require frequent battery changes
Smart faucets require lithium batteries which last 3 to 5 years. A blinking red light on Oras touchless faucets lets you know when it's time for a battery change, which you can easily do yourself within minutes.
Touch-on Faucets
Touch faucets have sensors in the spout and handle of the faucet that allow you to tap the faucet to activate water flow. While these faucets can be turned on with the quick touch of a finger, forearm, or hand, they also have manual modes.
Eventually, sediment buildup causes the same pressure and flow problems that leaks or dents usually do. If your plumbing pipes are outdated, lime and heavy metal deposits or corrosion and rust may have clogged them. If your pipes are clogged, very little or no water will flow out of your faucets.
Touchless faucets require electricity to operate, whether through using batteries or by connecting to an electrical socket in the wall. Check the packaging of your touchless system before you order it to ensure you have the proper power source for it.
One of the major disadvantages is that they are more expensive than traditional faucets. Additionally, they may require more maintenance as the sensors and mechanisms can cause problems down the line. Another downside is that touchless kitchen faucets often have limited features that are standard using manual mode.

You may also need to replace the batteries since this is the primary cause of touchless faucets that stop working. Your batteries may have run out or are the wrong voltage, either way, it needs to be replaced.
It Saves Water
A hands-free faucet only turns on when you need it and then turns off automatically when you've finished using it.
Wrap some paper towels over the faucet after dampening them with vinegar. Allow 10 minutes for the towels to dry. Vinegar cleans and disinfects the faucet, and because it is a gentle acid, neither you nor your faucet will be harmed. Dry your faucet after wiping it down with plain water.
The light will also flash rapidly to indicate battery life is low when using batteries to power the faucet. The blue LED light indicates that you are in electronics mode. It will come on for two seconds whenever electronics mode is activated. The light will also flash slowly indicate battery power is running low.
An LED indicator light at the base of the faucet will shine blue when the “Touch” feature is activated. If the handle is in the “off” position, you may tap the spout or handle to turn off the light.
Touch2O® Technology kitchen faucets are powered by 6 AA batteries and Touch2O® and Touch2O.xt are powered by 4 AA batteries. Ordinary batteries will last up to one year with 20 minutes of usage per day. The LED indicator light on the base of the faucet will start blinking red when it is time to change the batteries.
In most modern models, the battery can be exchanged by homeowners within a few minutes as it's located in a small capsule under the washbasin and attached to the cable of the sensor. Changing the battery for a touchless faucet is quick and easy as in most faucets the battery is located in a battery case below the sink.
Rust or buildup
The most common issue that arises from a faucet is buildup on the fixture.
Touch faucets work with a single touch with any part of your hand, arm, even your head so you can still use them safely to reduce the risk of bacterial or germ spread. Touchless faucets work with sensors that respond to motion, sound, or heat (or a combination of those) to turn it on without having to touch it.
Solid-brass bodies last longest and require the least care, especially with hard water, which corrodes lesser metals. At $150 or so to start, these faucets also cost the most. If you aren't sure whether a fitting is solid brass, pick it up.
Even if your home's power goes out, your Delta Touch2O faucet can still be manually operated, so you're never without water when you need it.
Is there an aerator in the faucet outlet? If so, remove it, and try turning on again. These often get clogged from debris you shake lose in the lines during installation. Some faucets also require you to remove part of the valve after installation to flush the lines, then re-install.
