What Is A Delta Kitchen Faucet?

What Is A Delta Kitchen Faucet

Delta is a top kitchen manufacturer who sell many different types of kitchen faucets including touch or touchless taps. Many of their designs are extremely popular and they offer a fantastic range of products.

They are unique, durable and modern and look fantastic in your kitchen! The faucets available from delta are unconventional as well as affordable and many people are choosing to have them in their kitchens.

Delta is known for years of craftsmanship and knowledge and they are favoured by many!

Touchless faucets offer many fantastic improvements to your kitchen. They allow you to wash your hands, dishes, sink and clean your surfaces all without touching the tap itself.

They also save water as they stop you from turning the tap on too fast or running it for longer than necessary. 

However, although delta faucets are known for their durability, inevitably, they sometimes go wrong. 

How Do Touch And Touchless Faucets Work? 

Now, before we go any further into exploring how your Delta kitchen faucet (see also ‘What Are The Best Touch Kitchen Faucets?‘) may have malfunctioned, we must first understand how they work.

Touch faucets include two sensors, one in the handle of the faucet and one in the spout, where the water comes out of.

When you touch either of these sensors, it should trigger the solenoid valve, causing the water to turn on or off. Touchless faucets work in a very similar way, however, instead of detecting touch, they detect motion. 

There are many pros to having a sensor on your kitchen tap. They are fantastic for limiting the spread of bacteria in the kitchen, they work really well for those who struggle with mobility and they look fantastic.

Why Has My Delta Kitchen Faucet Stopped Working?

Why Has My Delta Kitchen Faucet Stopped Working

There are many reasons why your faucet may have run into some problems, so the best way to work out what is wrong is to rule out all the possible problems until you work out which one is causing your problem.

So, let’s get down to troubleshooting our Delta faucet (see also ‘How To Fix A Delta Faucet That Still Leaks After Replacing The Cartridge‘). 

Check The Battery Pack 

Checking if your Delta faucet’s battery is charged up is easy. It includes an LED indicator light.

When the light is blue, it indicates cold water is coming out of the tap. When the light is red, it indicates that hot water is coming out of the tap. 

Blue Light 

If you see a blue light on your Delta touch or touchless faucet, it means that everything is in order and working as it should be. 

Flashes Red Every 5 Seconds

When this indicator light is flashing, it means that your faucet needs attention and may be running out of battery.

On Delta products, if your faucet LED light is flashing red every 5 seconds while you are not using the water, this indicates a low battery.

Luckily, this problem is very easy to rectify, and all you need to do is change the batteries.

Permanent Red Light 

If the indicator light is stuck on red while you are not using the tap, this means that the battery is fully drained.

Again, this has a very simple solution. You simply have to change the batteries to get the faucet back up and running.

Flashes Red In Long Blinks 

If the LED indicator light flashes red in long blinks, then your faucet is telling you that something else is wrong.

You may need to contact Delta support if this happens. 

How To Change The Batteries 

So, if your faucet is telling you that the batteries are low, you simply need to change them.

Most Delta faucets are powered by AA batteries, however, the amount of these batteries required varies depending on the specific product.

Open up the battery pack to see how many batteries power your specific faucet.

Lack Of Water To Your Faucet

If your faucet seems to be reacting to your touch or motion and is indicating that it is releasing water by showing a flashing light, however there is no water coming out of your tap, there are a few things you can do to get this working again. 

First, ensure that the space under your sink is clear. This is where the wiring will be for your tap. Ensure that the valve is on and nothing is interfering with the wiring.

If there is anything metal beneath the sink that is in contact with the wires, this may be interfering with the connection so remove it or move it out of the way of the faucet.

Check the connection of the faucet with the battery pack, and check all wires for a loose connection.

If you can see a loose connection or you have identified a loose connection and you don’t feel comfortable fixing it yourself, contact Delta support so that they can help you fix it. 

Problems With The Solenoid Valve

This one may sound scary, however it is not too difficult to fix so don’t fret! If you’re faced with a flashing red light, you’ve attempted a battery change and the problem hasn’t been rectified.

Often, this is due to a malfunction in the solenoid valve. Before you begin any analysis of the solenoid valve, ensure you remove the batteries from the faucet so you don’t get any unexpected action from your faucet!

To troubleshoot the solenoid valve do the following:

  • Remove the clip from the mounting shank.
  • Remove the wire from the solenoid valve by pulling at it.
  • Replace the solenoid valve with a new one. Be careful here as you are working with electricity near to a water source!
  • Link it all back up to see if this has fixed the warning light.

Check The Spray Head

Sometimes, the tap head becomes blocked and filled with debris. If this happens, clean it out to ensure that the debris isn’t stopping the water from coming out of the tap.

The TouchPad Or Motion Sensors Are Broken 

Occasionally, the sensors on your faucet fail to work properly. If this happens, or they only work some of the time, you’ll have to check the wires under the sink.

Make sure they aren’t crossed and haven’t been knocked. If you can’t find the problem, you may need to get in touch with a plumber or Delta support!

It may sound silly, but ensuring that the sensors are clean is essential to the functioning of the faucet.

If there is something covering the sensor, it will fail to work. This may explain the problem if your sensor works intermittently.

Sometimes, in this case, simply resetting the system may work. The trusty ‘turn it off and on again’ is still useful to this day!

Simply take out the batteries from the battery pack, leave them out for 30 seconds and then replace them.

Call A Plumber

If you’ve tried all of the things above and your Delta kitchen faucet is still not doing what you need it to, call in a plumber to help to get your problem fixed or talk to Delta support!

These products involve a lot of complex parts and an expert will be able to troubleshoot the problem.

Final Thoughts

Hopefully, in reading this information, you found your problem and fixed it without too much hassle!

If so, you should be very proud of yourself, you saved yourself some money by doing it yourself and not to mention some valuable time! 

However, don’t fret if you didn’t find the root of your problem! These systems are very complicated and sometimes you’ll need to enlist the help of a professional.

Remember to sit back and relax while they fix the problem, safe in the knowledge that you did everything you could.
