What is Moen Motionsense technology?

Innovation in kitchen faucet functionality has never been greater than with Moen Motionsense technology.

This technology uses motion sensors to detect the presence of hands and open the tap water supply without physical contact. Moen Motionsense faucets are usually equipped with two sensors, one located at the base and the other at the top of the spout.

The wave sensor, the upper sensor, registers hand movements over the tap. Water flows with a single movement of the hand, making it easy and contactless to use.

The basic sensor, also called the Ready sensor, searches for everything under the tap, e.g. plates or cutlery. Filling pots or washing dishes is easy as the water flow starts when objects are detected.

A. No water flow

Check the power source and batteries

The first thing to do if your Moen Motionsense battery is a plug-in model is to check that the power cord is properly connected and that the outlet is working. Occasionally, the power cord may be loose or disconnected, which cuts off power to the Moen Motionsense faucet. Check the connection and make sure it is well connected.

On the other hand, if the battery is powered by batteries (such as AA batteries), make sure the batteries are properly installed and charged.

Check that the batteries are installed correctly with the correct polarity (+ and – signs) by opening the battery compartment. Replace worn or exhausted batteries with new ones.

Make sure the water supply valves are open.

The next step is to place the water supply valves under the sink. These valves control the flow of water to the Moen Motionsense kitchen faucet. For water to flow into the faucet, make sure these valves are fully open.

Turn the valves counterclockwise and then clockwise to ensure they are open.

This movement ensures that the accumulation of minerals or deposits will not damage the valves. Valves must be opened by turning them counterclockwise when closed.

This action will now allow the water to flow through the supply lines and into the faucet.

Please note that some Moen Motionsense faucets may have separate valves for hot and cold water supply. If your faucet has separate controls for hot and cold water, make sure both faucets are turned on.

Check the water lines for clogging

• Close the water supply valves.
• Disconnect the water supply lines from the faucet with an adjustable wrench.
• Place a bucket or towel underneath to catch the water.
• Check the water lines for blockages or debris.
• If debris is present, flush the lines by opening the water supply valves for a few seconds.
• Reconnect the water supply lines and make sure they are tight.
• Open the water supply valves and check the water flow at the tap.

B. Low water pressure

Check the aerator for debris buildup

The aerator is located at the end of the spout of the Moen Motionsense kitchen faucet. It usually looks like a small lid with holes or a mesh screen.

Depending on the model, the aerator can often be unscrewed by hand. If it's tight, you may need to use pliers; in this case, cover the aerator with tape or a piece of cloth to prevent damage.

After removal, carefully inspect the aerator for dirt, mineral deposits, or mud. These may be in the form of small particles or an obvious coating.

To remove loose dirt, wash the aerator under running water. Gently wipe away any stubborn dirt with your fingers. If necessary, clean the aerator with a toothbrush or a small soft-bristled brush, being careful not to damage the delicate parts.

After cleaning, assemble the aerator by screwing it to the faucet spout. Make sure it is tight but avoid overtightening as this can damage the threads.

Clean or replace the aerator

If you decide to replace your aerator, find a suitable replacement at your local hardware store or contact usME customer service. If possible, please include the model number to ensure you receive the correct replacement.

Using the methods described above, unscrew the old aerator from the faucet spout. Applying a small amount of penetrating oil or grease will help reduce drag.

By screwing the new aerator to the faucet spout, you can install it. Again, make sure it fits snug but not too tight.

Checking the water pressure in the supply lines

• The water supply valves under the sink must be closed. They are usually located on the surface of the faucet.
• Disconnect the water supply lines from the Moen Touchless Faucet with an adjustable wrench. Have a bucket or other container ready to collect any water that may leak out.
• After cutting the power cords, place them in a bucket or container.
• Turn the water supply valves counterclockwise to gradually open them. Observe the flow of water from the cut off supply lines.
• If the water pressure is low, even if the Moen Touchless Faucet is not turned on, there may be a problem with the water supply. In these situations, it is advisable to contact a licensed plumber who can identify and resolve the cause of low water pressure.

C. Abnormal behavior of the sensor

Check that the sensor window is not dirty or blocked

When you notice a sensor malfunction in your Moen Motionsense kitchen faucet, the first step is to check the sensor window for dirt, mineral deposits or other obstructions that could interfere with its operation.

The sensor window is usually located at the base or neck of the faucet. First, find the sensor window and examine it carefully.

Look for any signs of dirt or debris that may be blocking the sensor's ability to detect movement accurately. Over time, mineral deposits from hard water can build up on the sensor, adversely affecting performance.

If you notice dirt or grime on the sensor window, gently wipe it with a soft cloth or sponge.

Avoid using abrasive cleaners or materials that could scratch the surface of the window. You can use a mild detergent or a mixture of vinegar and water to remove stubborn deposits.

After cleaning the sensor window, test the Moen hands-free faucet to see if the abnormal behavior has improved.

Wave your hand or object in front of the sensor and see how it reacts. If the sensor is now constantly detecting motion, the problem has been successfully resolved. However, if the problem persists, it is time to move on to the next step in troubleshooting the Moen Touchless Faucet.

Reset the faucet by disconnecting the power or batteries

• If cleaning the sensor window has not corrected the malfunction, the next step is to reset the Moen Motionsense Kitchen Faucet.
• Depending on the model, the crane can be powered by batteries or directly from the electrical connection. If the device is battery operated, locate the battery compartment and remove the batteries. If the device is connected directly to a power source, find the power source and disconnect it.
• Damn itMoen Touchless Faucetunplugged for at least one minute to allow for a full reset.
• After the reset period, reconnect the power or insert new batteries.
• Test the tap to see if the sensor behavior has stabilized. If the problem persists, go to the next step.

Troubleshoot the sensor or control box

If the sensor behavior remains abnormal even after cleaning the sensor window and resetting the Moen Handsfree Faucet, there may be a problem with the sensor or control box.
