Delta Kitchen Faucet (Touch Or Touchless) Is Not Working

Delta and many other top kitchen faucet manufacturers sell several touch and touchless faucet products. They make life much easier, even if it’s just washing your hands without having to touch the faucet handle. However, like all other technology, touch and touchless faucets are bound to have a few hiccups here and there.

If your Delta touch or touchless faucet won’t turn on, it can be quite frustrating no matter how many times you clap your hands in front of the sensor or touch the faucet. If you wanted a manual faucet, you’d just buy one, right? Well, we’re here to help, so keep reading for a troubleshooting guide to get your faucet up and running in no time.

What Caused My Delta Kitchen Faucet To Stop Working?

Your touch or touchless Delta kitchen faucet may have struck for a number of reasons. While determining the exact cause of a malfunction can be tricky, you should be able to do so. Start with each possible culprit and troubleshoot them one by one.

How Do Touch And Touchless Delta Faucets Work?

Before we get started, let’s take a look at how these faucets work. Touch faucets, also known as touch or touch technology faucets, use technology similar to that of your smartphone. The faucet is equipped with two capacitive sensors, one in the handle and the other in the spout. If you touch either of these sensors, it triggers a solenoid valve that causes the water to turn on or off.

Contactless faucets operate in a similar way, although they do not require physical contact. Sensors in the faucet detect motion, such as your hand moving in front of the faucet, and trigger the solenoid valve, which turns the water on or off. Now that we understand how they work, let’s move on to troubleshooting.

How To Check The Status Of Your Battery Pack

Delta makes it super easy to troubleshoot battery pack problems. Your faucet’s LED indicator will tell you exactly what the status of your battery pack is. When the faucet is on, the indicator will turn blue when cold water is flowing and red when water is flowing.

However, if your faucet is off and blinking, it is trying to tell you something.

What Does The Red Light On A Delta Faucet Mean?

If your faucet is flashing red when it’s off, there are a few things it could mean. Delta’s system is simple: if it flashes once every five seconds, it’s a warning that you’re replacing the battery. If the blinking frequency increases to once per second, the battery has reached its final limit and needs to be replaced.

If the light remains red when the water is turned off, then your chance to catch the batteries before they fail has passed. Fortunately, nothing dramatic will happen. Just replace the batteries and you’ll be back in business.

Finally, if the light is flashing for an extended period of time, the faucet is in an error condition, so it’s time to contact Delta’s support.

What Does The Blue Light On The Delta Faucet Mean?

The blue LED on the bottom of the Delta faucet means that everything is fine and the touch sensor is active.

How Big Of A Battery Does My Touch Or Touchless Delta Kitchen Faucet Need?

How large of a battery your faucet requires depends on the type of faucet you have. For example, the Touch2O technology kitchen faucet is powered by 6 AA batteries. On the other hand, some of Delta’s other faucets are powered by 4 AA batteries.

How To Diagnose The Solenoid Valve

If you’ve replaced the batteries and the faucet still gives you an angry red flash, the culprit may be the solenoid valve. While this process may sound scary, it’s actually not that bad, but it’s not as easy as figuring out the faucet’s blinking light or replacing the batteries.

First, locate the solenoid valve in the cabinet under the sink. Before repairing the valve, take the batteries out of the package and set them aside. Back to the solenoid: pull the clip off the mounting handle.

There should be a clip that slides into a slot in the shank of the faucet. Remove the extended cord from the solenoid assembly by pulling. The extended wire goes from the faucet body along the hot and cold water supply lines. It plugs into the solenoid with a tip that looks similar to a headphone jack.

Once removed, you can replace the old solenoid with a new one. Before you start, make sure you ground yourself so you don’t send static through the connections because they are sensitive enough.

If the outlet shows the correct color, but still refuses to work, you can still blame the solenoid. However, before you point to the valve as the culprit, check the spout first. To do this, make sure the handle is in the closed position, then unscrew the hose from the sprinkler head. Check for debris at the nozzle inlet. If there is debris, clean it up before replacing it.

If this does not help, make sure the handle is in the closed position again. Under the sink, remove the hose from the solenoid valve, then go back over the sink and check the water flow. Then, reconnect the hose to the solenoid.

Disconnect the hose from the faucet to the solenoid and check the water flow again. This will tell you if water is flowing through the manual valve and reaching the solenoid. If there is water flowing to the solenoid, then the solenoid is the problem and you must replace the solenoid and electronics package.

Troubleshooting No Water

Considering that this is the job of the faucet, lack of water to the faucet is a problem. If the indicator light is flashing, indicating that the sink is on and active, but there is no water, try these steps.

To figure out what might be causing this, first clean the area under the sink. Touch technology is wired very precariously, and you don’t want anything touching it. Make sure the water shut-off valve under the sink is open and not bumped into the closed position.

If none of these solutions help, check the battery (if you haven’t already) to reset the system. Then make sure that the special wires that have been in place are not in contact with any metal under the sink. Make sure they are connected properly. Check each wire connection for loose connections, adjusting them as you go so they don’t cross each other or touch metal.

Part Of The Touch Zone Is Not Working

Sometimes, one of the sensors on your touch faucet will refuse to cooperate or will only work intermittently. If this is the case, check under the sink. Check the wires in the affected area to make sure they are not crossing or touching metal. If you can’t find anything wrong, you may need to seek the help of a plumber.

How Do I Reset My Delta Touch Faucet?

Resetting your Delta Touch faucet is quick and easy. You will need to remove the batteries from the battery compartment and wait about 30 seconds. Then, put the batteries in the battery compartment and your faucet is reset.

What To Do If You Have Tried Everything?

If you’ve tried everything you can think of to troubleshoot your touch or touchless Delta kitchen faucet and nothing seems to work, it may be time to call in the professionals. Sometimes, specific components can malfunction. Given the number of components in a touch technology system, identifying a specific component can be tricky.

So, if you’ve done everything you can and your efforts haven’t yielded results, call a plumber or contact Delta support.
