Delta has a wide range of touch faucets and due to its popularity and durability, Delta touch faucets are found in many kitchens. Its touch faucets make washing work easy in the kitchen but when the Delta touch faucet not working, it leaves you frustrated and with a sink full of dirty dishes.
You touch the Delta faucet body but water doesn’t come out. In this guide, we will see why your Delta touch faucet is not dispensing water when you touch it. Try our troubleshooting tips to get back the working Delta touch faucet.
Cause of Delta Touch Faucet Not Working
Delta touch faucets are built with modern and advanced technologies to give a reliable and convenient user experience. You can operate them with a simple touch. This feature makes them an ideal choice for many kitchens. However, like regular faucets, touch faucets also can encounter issues and stops working. Here are the causes of why your Delta touch faucet is not working.
Low Battery
The common cause of the Delta touch faucet not working is its drained batteries. Delta touch kitchen faucet gets powered by 4 AA batteries. Batteries give power to the sensors of the faucet so when you touch the faucet body, the sensor reacts and starts or stops the flow of water.
When the batteries are low, they won’t give power to sensors. Without power, the sensor can’t sense the signal when you touch the faucet.
So, how do you know if the batteries are the culprits behind your Delta touch faucet’s misbehavior? Well, it’s simple. You need to take a trip underneath your sink and remove the battery box cover. Look for the battery level indicator and check the battery level. If the batteries are low or depleted, it’s time to replace them.
Clogged Solenoid Valve
The main element of a Delta faucet that regulates water flow is a solenoid valve. A signal is sent to the solenoid valve to open the water flow when you touch the faucet body. An electromagnetic field causes a plunger inside the solenoid valve to move, opening the valve and allowing water to flow through.
Mineral buildup harm the solenoid valve. The solenoid valve accumulates buildup with time, which interferes with its proper operation. Buildup stops the valve from fully opening and inhibits the flow of water. It has an impact on how well the faucet works.
Slow or irregular water flow, a dripping faucet, or a faucet that won’t shut off are all indications of a clogged solenoid valve.
Malfunctioning Sensor
The sensor is the main component that separates Delta touch faucets from standard faucets. The sensor detects the user’s touch and initiates the water flow. The faucet would not be able to function as planned if it did not have a working sensor.
The touch sensor is situated in the faucet’s body and detects movements using modern technology. When the sensor senses human contact, it transmits a signal to the faucet’s control module, which enables the water flow.
There may be problems with the water flow if the Delta faucet’s sensor isn’t working properly. For instance, the sensor may not function properly if the batteries are not providing enough power, which might cause problems with water flow.
Electrical Problems
Due to electrical problems in the Delta touch faucet, it stops working. A faulty wiring or damaged power supply creates electric problems in the Delta fixture. If your Delta touch faucet is powered by an electrical supply instead of batteries, you need to check whether it is getting an electric supply or not. Check the electric outlet or wiring that supplies electricity to the Delta fixture.
Maybe the electric output is not providing enough power or its wiring is damaged, and the fixture won’t receive power to operate correctly.
Sometimes the water gets into the electrical components of the Delta faucet and creates a short circuit in its wiring. A short circuit can cause the delta touch fixture to not work.

Troubleshooting Steps For Delta Touch Faucet Not Working
Resetting The Faucet
One of the simplest and most efficient troubleshooting techniques is resetting the faucet. Resetting the faucet is similar to rebooting the computer, and this frequently fixes problems.
Turn off the water supply under the sink, then unhook the faucet from the outlet or take the batteries out to reset it. Any remaining electrical current can dissipate by waiting for a minute or two. Reinstall the batteries or plug in the faucet once more after that. Restart the water supply and check to see if the faucet is functional.
Cleaning The Solenoid Valve
Your Delta touch faucet may stop working or work slowly if the solenoid valve becomes clogged. Mineral buildup from the water might accumulate over time in the solenoid valve, reducing water flow.
Turn off the water supply under the sink before removing the solenoid valve from the faucet to clean it. To remove any mineral buildup or debris, soak it for a few hours in a bowl of vinegar or a descaling solution.

Inspecting The Sensor
The sensor, which detects your touch and initiates the water flow, is an essential part of your Delta touch faucet. After resetting, checking the battery, and cleaning the solenoid valve but your Delta sensor faucet is still not working, it’s time to look at the sensor.
Then, check to see if any debris or objects are blocking the sensor. The sensor could not recognize your touch if there is a tiny bit of dust or debris on it. Next, ensure sure the sensor wire connections underneath the sink are safe and connected correctly.
It could be necessary to replace the sensor if it is broken or not working properly. For assistance, get in touch with Delta customer service, and replacement instructions are provided in the faucet’s handbook.
