Why Moen Motionsense Faucet Turns On By Itself?

Defective Sensor

Defective Sensor

For a Moen Motionsense faucet, its sensor is an essential thing. It allows you to use the faucet without touching the handle. If the sensor is defective, it will cause an issue in detecting the movement of the hand and the faucet may turn on by itself.

One common reason for a defective sensor is dirt or debris on the sensor. Due to dirt, the sensor can’t detect hand movement and unwanted activation of water flow happens. Also, the sensor may malfunction due to overuse of regular cleaning. This impaired ability results in misinterpretations or total disregard of user actions around the faucet, resulting in spontaneous water delivery.

Start by cleaning the sensor with a soft, wet cloth to remove any dirt or debris that may be obstructing it. Once the sensor is clean, it should be able to detect hand movements properly.

Water Pressure Issue

If your Moen Motionsense faucet turns on by itself, there may be a water pressure issue with the faucet. Sometimes when the water pressure is high, the faucet can’t stop the flow of water and water comes out from the Moen touchless faucet without any hand movement.

Sudden changes in the water pressure level can trigger the water flow from the faucet and cause water to flow from the faucet even when the user is not present around the faucet. You may use a pressure-regulating valve to control the water pressure.

Electrical Problem

Electrical Problem

For the sensor, the Moen Motionsense faucet gets power from batteries or electricity, depending on the model. If there is any issue with the power supply of the Moen tap, the faucet may turn on by itself.

If your Moen hands-free faucet is powered by batteries, the low power of the batteries is a common cause of this situation. With the low power of the batteries, the faucet’s sensor can’t perform properly. If the Moen faucet is getting powered from an electrical source then a loose connection can cause this issue. A short circuit in the power outlet box might be the reason for the automatic turn on the Moen faucet.
