If you have a Delta Touch faucet in your home, it may stop working from time to time. When this happens, you’ll need to troubleshoot the problem and fix the faucet as soon as possible.
A Delta Touch faucet is a high-end faucet that comes with exceptional features and an intuitive design. However, like any other technically advanced product on the market today, these faucets can also break down at any time.
But if it’s become a persistent problem, how do you troubleshoot and repair it? Let’s find out.

Take Care Of Any Quick Fixes First
Before getting into the more nitty gritty fixes, there are various things you can check to see if the most common issues are the source of your problem.
- Look at the spray head to make sure it’s not clogged
- Make sure batteries are in good condition and oriented correctly
- Check the handle to make sure that it’s mounted securely and hasn’t come loose
- Verify that the sensor wire hook is securely connected to the faucet’s shank
- If the faucet is stuck in one position and won’t open, check for corroded or damaged parts on the linkage rod
- Make sure that all parts are fully seated and that the unit is securely connected to the sink
- Make sure that the wires aren’t touching each other, or anything else
Delta Touch Function Issues
The touch function on the Delta faucet is an advanced feature that allows you to use a single tap to operate all functionalities such as temperature, flow rate, and more.
However, sometimes the touch feature doesn’t work as expected. In most cases, it is a power issue that’s causing the faucet to fail. Look at the battery compartment to ensure the batteries are working and verify that the unit has power on it by checking the LED lights system.
Some other steps include:
- Ensure that the faucet valves are turned on (find these under the sink) and that water is flowing
- Refasten any loose connections
- Rearrange the wiring (found beneath the sink), making sure they’re not touching each other (generally they work best with 2 inches between them) or anything else
Another possible cause of a non-working touch function is a damaged cable connection or loose wire. To repair a faulty wire issue, consult your local faucet repair professional.
Only One Sensor Of The Delta Touch Function Is Working
Your Delta Touch might have one touch sensor that works and another that is unresponsive. The wiring beneath the sink is usually to blame when this occurs.
- Fixes For The Delta Touch Function
The wiring diagram for the sensor can be found in the instruction manual. Make adjustments to the wiring using the steps above to resolve the issue.
If neither of the above faucet function solutions works, you should call a professional plumber in order to repair any damage caused by broken wires or improper installation.
LED Light Blinking?
LED lights are a fixture of the touch faucet industry. Their blinking usually indicates that there is something wrong with the water supply, so they should be checked out immediately.
The purpose of LED lights is to display if everything is in working order or a faulty condition in the battery compartment such as low battery power or system error. If the indicator light is flashing or fixed, there is a problem with the faucet.
The Meaning Behind The Delta Touch LED Lights
A blue light means that everything is in working order when the sensor is on. If the blue LED is flashing, it means that the hands-free mode is on.
The LED light will turn red if the batteries are almost out of juice. If they’re flashing red, however, this means the batteries need to be replaced ASAP. When the red LED is flashing in long bursts, there is a major system error that Delta can fix — or you can by following the next steps.
Delta Touch Faucet: How To Replace The Batteries
Battery sizes vary depending on the type of faucet you have. But most models are fuelled by four AA batteries. If you have a Touch2O though, these models are fueled by six AA batteries.
Here are the instructions for battery replacement in your Delta Touch:
Step 1: Find the battery compartment under the sink.
Step 2: Get rid of the old batteries and swap them out for new ones.
Step 3: Make sure the battery pack is properly locked up before closing it.
Step 4: Once the batteries have been changed and aligned correctly, reset the faucet’s functions by activating the reset button.
Check the LED light for flashing lights, and water flow from the faucet.
Having Changed The Batteries On The Delta Touch But It’s Still Not Working?
If you replaced the battery, but the LED red light is still flashing, then the solenoid valve could be to blame. This type of valve is usually used in applications where there is a flow of water but no pressure.
In other words, the solenoid valve allows you to control the flow of water without having to worry about the water pressure.
The process isn’t as bad as it sounds. It’s just more complicated than replacing your faucet’s battery or figuring out why it’s blinking.
Investigate The Delta Touch Solenoid Valve
Replace a solenoid valve only if there is no debris blocking the water flow. So first let’s check the spray head for issues.
Step 1: Check the spray head
- Make sure the handle is off.
- Remove the spray head from the hose.
- Make sure there is no debris in the spray head inlet. If the spray head is clogged with gunk, clean it out and reconnect it.
Step 2: Check the solenoid valve
If the first step didn’t do the trick, check the solenoid valve. Again, make sure to turn the handle to the off position.
- Locate the solenoid valve — you’ll find this in the battery compartment, beneath the sink.
- Remove the mounting shank by pulling the clip, then disconnect the hose from the solenoid to the faucet
- If there is water flowing to the solenoid but not through the faucet, then the solenoid needs to be replaced.
Step 3: Replace The Delta Touch Solenoid Valve
Most hardware department stores sell solenoid valves, or you can find them online.
- Remove the batteries before doing anything else.
- Remove the mounting shank by pulling the clip.
- Pull the wire from the solenoid assembly — the wire connection looks similar to a headphone jack.
- Replaced the old solenoid with a new one.
Delta Touch Faucet Dripping?
A dripping tap can lead to a few problems. It can be an annoyance, as it draws attention to your home, and it can waste valuable water. A dripping faucet can also gradually damage your pipes, which can lead to a whole host of problems, including leaks and water damage.
Mineral and calcium buildup can accumulate in the faucet’s aerator, causing the dripping.
The calcium combines with the dissolved minerals found in water to form a white residue that will harden over time. If your tap has been running for a while, it might have accumulated some mineral deposits.
How To Remove Delta Touch Calcium Buildup?
To remove the hardness from your tap, you need to use an acid-neutralizing chemical called calcium hydroxide, which neutralizes the calcium ions in your water supply so that they do not combine with other minerals to form a deposit.
If you don’t want to use a chemical product to remove mineral buildup, there are a few things you can try.
Step 1: Try soaking some cotton pads in vinegar and putting them over the faucet spout overnight. This should help break down the salts and allow them to drain into the sink
Step 2: Spray a half-and-half vinegar and warm water solution on the mineral deposit and let it sit for about thirty minutes before rinsing it with hot water. You can also try turmeric and baking soda
Step 3: Combine vinegar and warm water (half-and-half) in a sandwich bag. Put the bag on top of the spout of the faucet and secure it with an elastic. Leave the solution to do its job for as long as possible — preferably until the next day.
You can try the solenoid method above if you’re still experiencing problems with the faucet not working. You may also contact the manufacturer if you’re not comfortable replacing the solenoid valve yourself.
Be sure to dig around if your lifetime warranty is still valid if you are returning the device to the manufacturer.
To Sum Up
When Delta touch faucets were first released, they were the talk of the town. The features and functionality that come with this model are very impressive and unique.
However, like any other high-quality product that is prone to breaking down from time to time, these faucets have their shortcomings.
The main issue with these faucets is the sensor. Even though Delta claims that this feature is super intuitive and easy to use, the sensors have the ability to break down from time to time.
If issues occur check the following components:
- Batteries
- Wiring
- Solenoid valve
- The faucet for calcium buildup
