Why Did My Touchless Faucet Stop Working?

A touchless faucet does not have a handle and instead uses sensor technology. You need not touch the faucet, making it more hygienic and easier to use for those with arthritis or other medical conditions.

Your touchless faucet stopped working because of a dead battery on the touch sensor, water pressure is too low in your home, faulty solenoid valve, clogged sink, wrong handle position and a wrong sensor boasts triggering. To fix this, Check under your sink for hoses, washers, and any other pipes blocking the flow of water.

The above are explained below.

  1. The Battery on The Touch Sensor Has Died

When the battery dies, the faucet will stop working, and you won’t be able to turn it on with the touch of your hand. However, replacing the battery should do the trick if you can still touch the faucet handle and make it work.

  1. The Sensor Boasts Triggering

Another cause for a touchless faucet not working is that it’s triggered into thinking that someone is touching it when there isn’t anyone nearby. You might need to reprogram the sensor to stop triggering false alarms.

  1. The Water Pressure Is Too Low in Your Home

The weakest water pressure will make the faucet stop working. Check under your sink for hoses, washers, and any other pipes blocking the flow of water.

Also, you can try flushing out the faucet’s reservoir by turning it off and using only cold water for a few minutes before turning it back on again.

  1. The Sink Has Clogged

Another reason why your touchless faucet will stop working is because of a clog of some sort that’s blocking the flow of water. Unclog it by running water through it for a few moments.

  1. Faulty Solenoid Valve

If your touchless faucet has a solenoid valve and is not working, you will need to replace it. A solenoid is electromagnet; it should keep the faucet’s water off when the electricity is off. Something is wrong with the unit or its wires if it doesn’t.

  1. The Handle Might Not Be in the “Open” Position

Unless you’ve turned off the faucet, it should keep delivering water.

How Do I Bypass Moen Motion Sense? -Steps

Moen MotionSense is a system-enabled faucet that will turn on automatically when motion is detected in front of the sink and off 30 seconds after the last motion.

If you are experiencing problems with Moen Motion Sense, please contact the Moen Limited Warranty department for assistance. Below are steps on how to bypass Moen MotionSense.

Step 1: Shut off the water supply to the fixture at the valve behind the wall and under the sink, or turn off the water from the main shutoff valve.

Step 2: Remove the MotionSense cartridge from the faucet.

Step 3: Turn the water supply to the fixture at the valve behind the wall or under the sink, or turn on the water from the main shutoff valve.

Step 4: Install the replacement cartridge, careful not to touch the electronics portion of the Moen cartridge. MotionSense is now disabled (the motion of the handle will not turn on the water).

For MotionSense to function, you must remove the faucet handle rearward.

Step 5: If you have questions regarding this procedure, please contact the Moen Limited Warranty department for assistance.

Can Touchless Faucet Work Without Batteries?

Yes! Touchless faucets either work with batteries or an A/C connection to the home’s power supply. This is how the A/c connection to a touchless faucet works:

The A/C connection to the faucet sends a signal to close the handle. This signal then gets relayed through a fixed magnet on the faucet.

The magnet receives this signal and opens the handle, providing water when you let go of it or by closing it when you press at its bottom and then releasing it.

Furthermore, touchless faucets with batteries have a motion sensor that detects body motion and opens the handle when you wave your hand in front of it. It’s neat to have either both or one of these features in your kitchen.

The batteries in touchless faucets need to be replaced at regular intervals of 1, 2, or 5 years. The touchless faucet with an A/c connection generally lasts longer because it’s more durable and doesn’t require batteries.

This can be purchased and installed at home centers, hardware suppliers, or professional plumbers.

If you notice that your faucet moves by itself, you may have a broken sensor or loose cables to the sensors. You can fix this by replacing the battery or by tightening the cables.

Why Is My Touchless Faucet Dripping?

Most touchless faucet drips result from air getting trapped in the aerator. This is usually because the aerator has not fully seated into the faucet handle or if you have not properly dried it after cleaning.

If you see wet spots in your sink or find that your faucet handle turns very slowly, it’s probably time to check your aerator.

Factors that can contribute to aerator build-up:

  • The Aerator has not properly sat,
  • The faucet drips when you turn the water off, or
  • There is a problem with the internal valves of your faucet.

To solve this problem, clear out that bad aerator. You can remove it simply by taking it off your faucet and disassembling it. First, you need to remove any small pieces of debris that may be in your aerator.

Next, fill it halfway with vinegar. Turn the faucet on for 10 seconds, and then turn it off. Leave the faucet turned on for about 20 seconds; this opens all valve holes. Now rinse out the vinegar and dry it thoroughly with a towel.

Why Did My Touchless Faucet Stop Working?

Do not simply put a rag in your aerator and leave it there, as this will cause damage to your pipes. After removing your aerator, you can replace it with a new one (most plumbers recommend that you replace them every two years).

7 Common Issues with Touch Faucets and How to Fix

The Sprayer doesn’t come onA clog in the line is the most likely cause of this problem, and it’s easy to fix. To start:  

1. Unscrew the sprayer head below the faucet.

2. Remove any dirt or debris blocking its holes.

3. If that doesn’t work, grab a pair of needle-nose pliers and try to unclog it by pinching together one end of the restricting piece of debris.

The Sprayer or the Faucet DripsMost likely, this issue needs a trip to the store for a new washer. Unscrew the sprayer head and replace it with a new one using a screwdriver.


If you have trouble getting one, check with your local Home Depot to see if they can order you one.

The Faucet is looseAll faucets are plastic; over time, that plastic can become brittle, break down and crack.  

Before buying a replacement faucet, figure out what caused the original one to become loose.

If you installed it incorrectly or didn’t properly tighten it, then the only real solution is to replace the unit entirely.

It’s not easy to fix, and there are no guarantees that it will last as long as everything else in your house.

When your faucet is starting to come loose, check whether or not it swivels freely. If it does, loosen the set screw or cap screw on the faucet and check if the stem can move.

If it can, your faucet is loose, and you’ll need a new one.

If all else fails, call a plumber and have them fix your faucet instead. The cost will be much less than purchasing a new one, and with their expertise, you’ll probably be able to avoid replacing the whole thing.  
The Faucet leaksYou can identify whether or not your faucet is leaking by disconnecting the supply lines, the pipe that runs up to your faucet from the hot and cold-water supply lines in your walls.

Use a pipe wrench to turn the fitting just below where they connect to your faucet. After you disconnect everything, place a pan under the connection and turn on hot and cold water for about 20 seconds.

Direct the water through the holes on the right; you may leak if it dribbles out of the bottom.

You’ll need to replace the line if this doesn’t unclog your line. Before replacing it, ensure all valves are in the “off” position.

Also, test your faucet to see if it’s still leaking. To do so, turn on the cold water and close the hot-water valve.

If you can’t immediately identify where the leak is coming from, watch while you run both hot and cold water.

When your new faucet is leaking, call a plumber to have them fix it. It could be a simple fix, just as long as you have one sized correctly for your faucet.
The Faucet won’t turn offIf you press the button on the handle of your faucet, it shouldn’t turn off. If it does, and you’ve determined that none of the other issues with your faucet are causing this problem, then you’ll need a new button.


The most common problem is that you have a leak in the line or somewhere where it shouldn’t be leaking.  
The handle sticksIf your faucet handle is sticking, first make sure it’s not just the button on the end of the knob.


The small button on the end can get stuck underneath a screw that gets tightened and never comes loose again. If this is the case, you’ll probably have to loosen it using needle-nose pliers to pry it off gently.

Grab your pliers and grab hold of one side of the plastic insert that holds the screw in place.

Put the tool on one of the tips and then tighten it to wedge it up under where the screw should be.

When you get underneath, unscrew it so you don’t damage the plastic surrounding it.

If you notice that this is what’s preventing your knob from turning, unscrew the screw and remove your knob. Or take them both out of your faucet and store them safely away for later use.
The Hot water handle sticksThere is usually nothing wrong with the faucet itself. Being a common household appliance, you’re probably making your hot water and accidentally turning it too high.


The pressure forces the handle to release when the temperature rises to a certain point, but it’s just stuck again.

To solve this problem, turn off the hot water supply and wait for it to cool before turning it back on again. This should prevent your problem from occurring again in the future.

How To Choose the Faucet That Suits You?

Below are some tips to help you choose a faucet that will suit your needs.

  1. Consider Your Budget

Consider your budget when buying a faucet. For example, if you have the money to buy a high-quality faucet but are on a limited budget, consider buying something that is not as expensive or high quality but still has everything you need.

  1. Consider Your Needs

Do you want a self-cleaning faucet? Do you want a faucet for washing the dishes? If you want your faucet to be for multiple purposes, go for one with at least two handles, even if it is just a single handle.

  1. Consider Your Needs in The Kitchen

Always think of how the faucet will fit into the existing set in your kitchen. It’s important to match the faucet with the rest of the appliances in your kitchen.

  1. Consider How Easy the Task Will Be

Think of how often you will do this particular task and choose a faucet accordingly. If it’s only once or twice a month that you clean dishes, then go for a one-handle faucet because it will not consume much water to clean up your dishes.

  1. Consider Your Style

If you don’t want a faucet to take up much space in your kitchen, go for a smaller one with less depth. The smaller faucet will also have less water capacity, so it won’t be wasteful if you don’t use all the water in your bathroom.

  1. Consider the Material

Most faucets comprise brass, bronze, nickel, or ceramic. Choose the faucet depending on the material that you like most. The most popular materials are stainless steel, high-grade brass, and other types of alloys.

  1. Consider the Design

Don’t fixate too much on this factor, but you should know its design before buying it. Consider how the different designs will look in your kitchen when choosing a faucet.

How Do Touch Kitchen Faucets Work?

Touch kitchen faucets boast sensors in the spout and handle that allow you to tap the faucet to activate water flow.

You can calibrate the sensors for hands-free operation by tapping the sensor with a wet hand or add sensors for hands-free operation to a faucet that does not have them.

When water is not flowing, you can lift the handle to activate water flow or press the lever that activates water flow.

Why Did My Touchless Faucet Stop Working?

There are two ways to activate the touch sensor on a touch kitchen faucet:

  • Without the spout in hand: The water flows through the plastic tube (red) in the spout when you try to activate it and stops when you release it.
  • The supply voltage gets applied across the two keyed terminals (purple). Touching one or both terminals shortens the circuit and delivers power to the sensor. A wet hand can close the circuit at the spout.
  • With the hand holding the faucet: The water flows through the plastic tube (blue) in the handle when you activate it and stops when you release it.
  • The supply voltage gets applied across two terminals on the handle (green). Touching one or both terminals shortens the circuit and delivers power to the sensor. A wet hand can close the circuit at either or both terminals.

5 Common Myths About Touch Kitchen Faucets

Touchless faucets need frequent battery changes

Touchless kitchen faucet models use the same battery you use in your coffee maker or electric toothbrush. So there is no need to waste time and money replacing batteries every few weeks.

Touchless faucets don’t make as good of a stream as regular faucets.

Because their operation depends on a sensor instead of gravity, touchless kitchen faucets use water pressure to ensure that you get a consistent stream of water, regardless of your hand position.

They’re Expensive

Some large-size touchless faucets are more expensive than equivalent brands with traditional valves. Still, many touch-operated models are very affordable and have some impressive features, too.

They need to get installed by a plumber or professional technician.

While you may need a professional to hard-wire the faucet, most models don’t require special tools or skills.

They’re Difficult to Clean

Many touch kitchen faucets have removable spray heads, which makes it simple to put the head in the dishwasher and makes cleaning a breeze.

How Do You Fix a Faucet Water Sensor?

Faucet water sensor problems can be inconvenient, but homeowners can fix them themselves. Here are simple steps to deal with a faulty faucet water sensor.

  • Unplug the faucet from the outlet and run cold water until there is no more flow from the faucet.
  • Remove the front panel if necessary, by removing the screws on top of it and lowering it slightly while keeping a firm grip on all parts.
  • Look behind the faucet and locate the sensor after opening up the panels.
  • Disconnect it from the hose. You can clean it using a damp cloth or a new one.
  • Close up everything and plug in the faucet to test it out.
  • If there are issues, make multiple changes until your sensor works properly.
  • If you do not want to deal with more problems in the future, contact a plumber.

Why Does My Touchless Faucet Turn On By Itself?

The most logical reasons why your touchless faucet turns on by itself are:

  1. Worn out Packing nuts

This happens when you haven’t tightened the packing nuts in the faucet properly, which causes delicate gears and other parts to break down over time.

  1. Faucet was loose from the Packing

Most probably, this is due to the losses of a pair of two or more screws on the faucet not being completely tight, which loosens up and causes this problem.

  1. Over-Tighten Packing Nuts

The hardest part of releasing your touchless faucet is often over-tighten packing nuts, but it’s also possible they are loose in the first place or not tight enough.

  1. The Device Was “In the Wrong Place

Especially important when repairing a touchless faucet: check where it should sit before you put your hands into the device because you better notice and fix an issue that you might not see when it’s ON.

  1. Worn-Out Material on The Drive’s Motor

This may be true if your touchless faucet is over-driven or has worn-out materials not removed from the motor (usually from rust).

  1. Worn-Out Material on The Drive’s Gears

If your touchless faucet is still powered, there may be some friction that makes the faucet not move freely.

  1. Worn-Out Material in The Device’s Handle

The turning handle of a touchless faucet may get worn out over time; this is especially true if you have used the device for a long time.

Do Touchless Faucets Break?

Yes! Touchless faucets do break when:

  • An object that is too large damages the faucet.
  • The faucet has a loose valve stem, and water leaks when you turn it off.
  • The faucet has a flexible handle, and water flows when you turn it off.
  • The solenoid valve is malfunctioning or needs replacement.
  • The wiring or the water pressure is too high, which can lead to shorts in the system.
  • The power to the faucet’s solenoid valve is not working properly.
  • Another possible reason for broken touchless faucets is low water pressure. This can occur in areas where there was a recent replacement of the water main and may occur if water pressure has decreased.

Step 1. Ensure you turn off the power to your entire house, and then turn on a backup supply. Water supply lines can be as short as 2 feet, so be sure your backup has enough pressure to run a houseful of fixtures.

Step 2. Try turning the faucet on by hand. If it’s not working, then there is a loose valve stem. This is most likely caused by the actions of children or pets in the home.

The stem can easily shear off without ever leaking fluid or getting wet, and you may need to replace it with a new stem if you have pets.

Step 3. If the faucet is still not working properly, check the valve stem. You can do this easily by observing the water pressure when you open it.

If the water pressure is low, there may be a leak in the valve stem. Remove the loose portion of the stem and tighten it with pliers or a nut driver. Then replace it with a new stem.

Step 4. If you can’t fix your touchless faucets at home, call a plumber to replace them.


Touchless faucets have become popular in recent years. They are a more sanitary solution to food preparation and drinking.

However, they are not suitable for all situations. If you use your kitchen extensively or have children or pets, then a touchless faucet is probably not the best solution.
