What Is Moen Motionsense Technology?

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

This technology makes use of motion sensors to identify the presence of your hands and turn on the water flow of the faucet without making physical contact. Two sensors are normally included with Moen Motionsense faucets: one is located at the base and the other is at the top of the spout.

The Wave Sensor, the top sensor, picks up hand motions above the faucet. The water flows with just a wave of your hand, making for a convenient and touchless experience.

The base sensor, referred to as the Ready Sensor, looks for anything beneath the faucet, like dishes or cutlery. You can effortlessly fill pots or wash dishes because the water flow is initiated when objects are recognized.

Moen Motionsense Kitchen Faucet Troubleshooting Steps

A. No Water Flow

Checking The Power Source and Batteries

The first thing you should do if your Moen Motionsense faucet is a plug-in model is to make sure the power wire is connected correctly and that the outlet is working. There may occasionally be a loose connection or disconnection in the power cord, cutting off power to the Moen Motionsense faucet. Verify the connection and make sure it is plugged in firmly.

On the other hand, if your faucet is powered by batteries (such as AA batteries), you must ensure that the batteries are properly installed and charged.

Check that the batteries are correctly positioned with the appropriate polarity (+ and – signs) by opening the battery compartment. Replace any worn-out or depleted batteries with new ones.

Verifying Water Supply Valves Are Open

Finding the water supply valves under the sink is the next step. The water flow to the Moen Motionsense kitchen faucet is regulated by these valves. To enable water to flow to the faucet, make sure these valves are completely open.

Turn valves counterclockwise and then clockwise to make sure they are open.

This motion makes sure that mineral or sediment accumulation hasn’t caused the valves to become stuck. The valves must be opened by rotating counterclockwise if they are closed.

Water can now move through the supply lines and enter the faucet as a result of this activity.

It’s important to note that certain Moen Motionsense faucets may have separate valves for the hot and cold water supplies. If your faucet has separate controls for hot and cold water, make sure both valves are open.

Inspecting The Water Lines For Blockages

• Turn off the water supply valves.
• Disconnect the water supply lines from the faucet using an adjustable wrench.
• Place a bucket or towel underneath to catch any water.
• Inspect the water lines for any obstructions or debris.
• If there is debris, flush the lines by turning on the water supply valves for a few seconds.
• Reconnect the water supply lines, ensuring they are securely tightened.
• Turn on the water supply valves and test the faucet for water flow.

B. Low Water Pressure

Examining The Aerator For Debris Buildup

The aerator is at the end of the spout on the Moen Motionsense kitchen faucet. Typically, it looks like a tiny cap with perforated holes or a mesh screen.

The aerator can often be unscrewed by hand depending on the model. If it is firmly fastened, you might need to use pliers; in that case, be sure to cover the aerator with tape or a piece of cloth to prevent harm.

After removal, thoroughly check the aerator for any debris, mineral buildup, or sludge. These can take the form of minuscule particles or an obvious covering.

To get rid of any loose debris, rinse the aerator under running water. Rub any obstinate rubbish gently away with your fingers. If required, clean the aerator with a toothbrush or a small brush with soft bristles, taking care not to harm the delicate parts.

After cleaning, reassemble the aerator by screwing it back onto the faucet spout. Ensure it is tightened securely but avoid overtightening, as it may damage the threads.

Cleaning or Replacing The Aerator

If you choose to replace the aerator, look for an appropriate replacement at a nearby hardware store or get in touch with Moen customer service. If at all feasible, give them the model number to make sure you get the right replacement.

Using the methods described above, unscrew the old aerator from the faucet spout. Applying a small amount of penetrating oil or lubricant will assist loosen any resistance.

Screwing the new aerator onto the faucet spout allows you to install it. Once more, make sure it is snug but not too tight.

Checking Water Pressure In The Supply Lines

• The water supply valves under the sink should be closed. These are typically found on the faucet’s pipe’s surface.
• Disconnect the water supply lines from the Moen touchless faucet using an adjustable wrench. A bucket or other container should be ready to capture any water that may come out.
• Place the supply lines in the bucket or container after they have been cut off.
• Turn the water supply valves counterclockwise to gradually open them. Watch the water flow from the supply lines that have been cut off.
• If the water pressure is low even while the Moen touchless faucet is not turned on, there may be an issue with the water supply. It is advised in these situations to get in touch with a licensed plumber who can identify the cause of the low water pressure and fix it.

C. Erratic Sensor Behavior

Inspecting The Sensor Window For Dirt or Obstructions

When experiencing erratic sensor behavior with your Moen Motionsense kitchen faucet, the first step is to inspect the sensor window for any dirt, mineral deposits, or other obstructions that may be interfering with its operation.

The sensor window is usually located at the base or neck of the faucet. To begin, locate the sensor window and carefully examine it.

Look for any signs of dirt or debris that could be blocking the sensor’s ability to detect motion accurately. Over time, mineral deposits from hard water can accumulate on the sensor, affecting its performance.

If you notice any dirt or debris on the sensor window, gently clean it using a soft cloth or sponge.

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

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

Wave your hand or an object in front of the sensor and observe how it responds. If the sensor now detects motion consistently, you have successfully resolved the issue. However, if the problem persists, it’s time to proceed to the next troubleshooting step for the Moen touchless faucet.

Resetting The Faucet By Disconnecting Power or Batteries

• If cleaning the sensor window did not resolve the erratic behavior, the next step is to reset the Moen Motionsense kitchen faucet.
• Depending on the model, the faucet may be powered by batteries or a direct electrical connection. If it’s battery-powered, locate the battery compartment and remove the batteries. If it’s directly connected to power, locate the power source and disconnect it.
• Leave the Moen touchless faucet disconnected from power for at least a minute to allow for a complete reset.
• After the reset period, reconnect the power source or insert new batteries.
• Test the faucet to see if the sensor behavior has stabilized. If the issue persists, proceed to the next step.
