Touchless faucets have become increasingly popular in recent years due to their convenience and hygiene benefits. However, one issue that can occur with touchless faucets is that they may turn on by themselves, leaving you scratching your head and wondering why.

There are a few reasons why is my touchless faucet turning on by itself:

1. Electrical Interference

One of the most common reasons for touchless faucets to turn on by themselves is electrical interference. This interference can come from a variety of sources, including nearby electronic devices, power surges, or even lightning strikes.

If your touchless faucet is turning on by itself, try moving any nearby electronic devices away from the faucet, and ensure the faucet is grounded correctly. It may also be helpful to install a surge protector to protect the faucet from any sudden electrical surges.

2. Dirty or Damaged Sensor

Another reason for touchless faucets to turn on by themselves is a dirty or damaged sensor. Over time, the sensor may become covered in dirt or grime, making it difficult for the faucet to distinguish between motion and no motion.

To resolve this issue, clean the sensor with a soft cloth and a mild cleaning solution. Ensure the sensor is completely dry before using it again. If the sensor is damaged, it may need to be replaced entirely.

3. Low Battery

If the battery in your touchless faucet is running low, it may cause the faucet to turn on and off sporadically. This is because the battery is not providing enough power to the faucet to keep it functioning correctly.

To remedy this, replace the batteries in the faucet with new ones. Be sure to use the correct battery type recommended by the manufacturer to avoid any further issues.

4. Faulty Solenoid Valve

In some cases, a faulty solenoid valve may cause the touchless faucet to turn on by itself. The solenoid valve controls the flow of water through the faucet, and if it is not functioning correctly, it may cause the faucet to turn on unexpectedly.

If you suspect the solenoid valve is faulty, contact the manufacturer or a licensed plumber to have it repaired or replaced.

Why does my automatic faucet keep running?

If you’re experiencing an issue with your automatic faucet not turning off, there are a few steps you can take to troubleshoot the problem. Firstly, ensure that all connections are secure, and there are no leaks in the system. If the faucet is still running, check for any obstructions or dirt in the parts, as this can cause the faucet to malfunction.

If everything else appears to be in good working order, the issue may be due to a faulty solenoid valve. The valve may not be fully closing, causing the faucet to remain open. In this case, the solenoid valve will need to be replaced to restore the proper functioning of the faucet. It’s best to consult a professional plumber or the manufacturer to ensure the replacement is done correctly.

How do you reset a touchless faucet?

Once you have replaced the batteries in your faucet, you may need to reset the device. To do this, you should first locate the battery compartment underneath the sink, and remove the old, dead batteries.

Next, open the battery case and ensure that the new batteries are properly aligned with the positive and negative poles in the correct positions, according to the layout provided in the battery compartment. This will help to ensure that the faucet receives the correct amount of power and can function correctly.

Once the new batteries are in place, you may need to reset the faucet according to the manufacturer’s instructions. This may involve pressing a specific button or switch on the faucet, or following a specific sequence of actions to restore the faucet to its default settings.

By taking these steps, you can ensure that your faucet is properly powered and reset, so that it can function correctly and provide you with the reliable performance that you expect.


There are several reasons why a touchless faucet may turn on by itself. Reasons including electrical interference, a dirty or damaged sensor, low battery, or a faulty solenoid valve. By understanding these potential causes, you can take steps to troubleshoot the issue and get your touchless faucet back to working correctly.
