List of Main Issues With Delta Touch Faucets

1. Light Blinking Red

The LED light on a Delta Touch kitchen faucet serves as an important indicator of its operational status. When the red light starts blinking, it’s a signal that the batteries need to be replaced in order to maintain the touch functionality.

It’s important to attend to this promptly, but if for some reason the batteries are not replaced, the faucet will still be able to function through manual operation.

 On the other hand, if you see the blue LED, it means that everything is working as intended and the touch sensor is ready to activate. However, if you observe long red blinks, it could be a sign of an error state that might need to be further investigated or addressed.

How to Fix it

If you notice that the LED light on your Delta Touch kitchen faucet is blinking red, it’s time to replace the batteries. The process is straightforward, and you’ll need six AA replacement batteries.

 First, locate the battery pack beneath the sink, and open the door to access it. Remove the old batteries and insert the new ones according to the polarity shown on the box. 

Then, reinstall the cap over the new batteries and position the pack back in its original place. Make sure the cable is free from obstructions and check your faucet for proper function. If the light continues to flash even after replacing the batteries, it’s likely that you need to replace the solenoid valve.

However, if you observe long red blinks, this indicates an error with the system. In this case, you should contact Delta’s customer support for further assistance. They can provide guidance and recommendations on fixing the issue or refer you to a licensed plumber to address the problem.

2. The faucet Turn on By Itself

If you have a Delta touch faucet that seems to turn on by itself, it could be due to several underlying factors. One of the primary reasons for this problem is inconsistent water pressure, which can cause the valve or pressure switch to malfunction, leading to unexpected activation.

 Another cause may be a fault in the faucet assembly itself, which can cause the faucet to turn on randomly.

In some cases, the problem may stem from issues with the grounding clips. If the clips are not properly secured, it can cause the faucet to turn on by itself. 

Another possible cause is that the battery pack may be touching something else, and not at least 2″ away from the faucet, which can trigger the faucet to turn on unintentionally.

How to Fix it 

Firstly, it’s important to disconnect the faucet from power to ensure your safety. If your faucet was manufactured before February 2009, check the grounding clips to ensure they’re securely in place and grounded. 

If your faucet was manufactured after this date, it doesn’t require grounding, so check the spout insulation components to ensure they’re in place and preventing electrical contact with the sink.

Next, check the wiring and sensors to ensure they’re properly connected and not damaged. It’s important to handle this part of the repair carefully, as water and electricity don’t mix. If you’re not comfortable doing this, consider seeking the help of a professional plumber. 

Additionally, make sure the supply valve is open and that you press and hold the reset button for 3 seconds.

Finally, check the battery pack to ensure it’s not touching anything except the wood it’s sitting on, and that it’s at least 2″ away from the faucet assembly itself.

3. Delta touch faucet turns off slowly

If your Delta touch faucet is turning off slowly, it could be due to several reasons, including a worn solenoid valve, dying batteries, or worn-down rubber seals and springs in the valve body. 

How to fix it

First, check the battery compartment to make sure it is closed completely. If the battery compartment is not closed all the way, it can cause the faucet to turn off slowly. Ensure that the batteries are fresh and have enough power to operate the faucet.

Next, check and replace any worn-down parts such as the solenoid valve or rubber seals and springs. A worn-down solenoid valve or rubber seals and springs can cause the faucet to turn off slowly. Replacing these parts should help restore the faucet’s proper function.

It may also be necessary to reset or replace the valve if these steps do not resolve the issue. In some cases, contacting Delta’s Smart Faucet Concierge Support Team may be necessary for further assistance. 

4. Delta Touch Function Not Working at all

If the touch function on your faucet stops working, it may be due to a lack of power, caused by dead batteries or a power interruption. 

How to Fix it

To fix this issue, check the battery pack for working batteries or verify there is the power to the unit.

In addition, you should check that the water supply is flowing properly to the faucet. Sometimes, the valves underneath the sink might be closed, causing a lack of water flow. Verify that both valves are on and that there is water flow to the faucet.

Another reason for the touch function not working could be due to crossed or blocked wires, which can cause issues. Check the wiring underneath the sink to make sure it isn’t touching anything, and the wires aren’t crossed. 

Rearrange the wiring as necessary, and make sure that the wires aren’t touching any metal components. If you find any loose connections, refasten them and move the wiring to avoid contact with metal components.

It’s essential to be cautious when handling the electrical components of the faucet, as water and electricity can create a hazardous mix. If you’re uncomfortable handling the repair yourself, consider enlisting the help of a professional plumber who can ensure that the faucet is working correctly.

5. The Faucet is Not Working  even after the Battery Replacement

The reason your Delta touch faucet is not working after battery replacement could be due to a faulty solenoid valve, incorrect battery installation, faulty wiring, or a touch sensor malfunction.

How to Fix it

If your Delta touch faucet is not working after replacing the batteries, you should first check that the batteries are inserted correctly and reset the system by disconnecting them for at least 30 seconds. 

If the issue persists, you should investigate the solenoid valve and replace it if necessary. If only one touch area is not working, check and rearrange its wiring. If all else fails, it may be time to replace your Delta Touch faucet altogether.

If you need to replace the solenoid in your Delta Touch kitchen faucet, you can purchase the Delta Faucet EP74854 Solenoid Assembly, which is specifically designed for this purpose. This replacement solenoid can help fix issues caused by a malfunctioning or broken solenoid.

To install the new solenoid, you will need to remove the mounting shank by pulling the clip and then replace the old solenoid with a new one. It’s important to note that you should turn off the water supply before attempting to replace the solenoid.

Once you have successfully installed the new solenoid, you can turn the water supply back on and test the faucet to ensure it is functioning properly.

Why does my faucet have low water pressure?

The most common reason for low water pressure in a Delta Touch kitchen faucet is a clogged aerator. To fix this, remove the aerator and clean it, ensuring that the debris screen is clear. Flushing the system can also help.

How to adjust the water pressure in a kitchen faucet

To adjust the water pressure in a Delta Touch kitchen faucet, check that the valves under the sink are on and water is flowing. Then turn off the water supply to both hot and cold, remove internal components under the handle(s), and turn the water supplies back on for 30-60 seconds. Remove debris from the valve if necessary, refasten loose connections, and rearrange wiring if needed. Finally, remove the flow restrictor from the wand and make sure there is good flow with it.
