1. Depleted Batteries

When you experience the Delta touch faucet blinking red light on the base of the spout, the matter probably is just about to change the batteries. 

Because whenever the Delta touch faucet blinks red it indicates the battery is depleted and needs to be replaced. 

So, only by replacing the batteries, sort out the matter hopefully without any further fixes. 

How To Change The Batteries on Delta Touch Faucet

The process is a very easy fix to be done. Just follow the steps as described. 

Step 1: To change the batteries, locate the battery pack of your Delta faucet in the cabinet under the sink. 

First thing is to make sure the top of the battery pack is securely fastened. If it’s fastened properly, move ahead to the process of changing. 

Step 2: Now hold the battery box & press on either side of the box. It’ll remove the top cap of it. 

Take out the old batteries & install the new ones just as the polarity of the batteries is shown in the box. 

Because if you put the batteries in the wrong direction, it won’t operate the touch faucet. Replace the cap of the box and reconnect it to its spot. 

Delta Recommendations: For the best result of your Delta touch faucet activity, place the battery pack on the floor of the cabinet as close as possible. Put the box flat on the floor & maintain a minimum 2“ clearance around the battery pack. 

2. Messy Connections

If the simple battery fix can’t work out & still Delta touch faucet flashes red, there are other things you need to check. That is the connection of your Delta touch faucet solenoid. 

Anyhow when the wires connected to your solenoid come undone, you experience the Delta touch faucet 3 red blinks. 

Even if there are a lot of actions going on under the sink, that could get the wires bumped loose. 

Plus, the clip connection on the threaded shaft also needs to be checked. It’s a metal connection on the metal shaft that allows the touch sensor of the faucet to work. 

Solutions:

• If you look underneath your sink, you will notice there are two blue clips and a little box right in the middle of those clips. That’s your solenoid. 
• You can see some wires running into the solenoids. Now you have to ensure all the wires connected to the solenoid that comes to the faucet haven’t come undone & plugged in properly. 
• Also, check the C-shaped metal clip connected to the threaded shaft with a wire. Just how it looks in the image. 
• If the clip comes out, you may face the Delta touch faucet not working and blinking red light. In that sense, check if the clip is in its exact location. 

Plus, there should be no obstruction or messiness around the wires that can loosen or undo the connections.

3. Flawed Solenoid

Outside of these easy fixes, still having the Delta touch faucet red light flashes 3 times, then that can mean the solenoid valve needs to be replaced. 

To turn on the Delta faucet and to turn it off, the solenoid works accompanied by the touch sensor. 

When the solenoid wears out, you may face the Delta touch faucet flashing red light. So, it can be an indication of the solenoid replacement. 

How To Change The Delta Touch Faucet Solenoid

ii) Remove The Hose

Now it’s time to remove the hose. First, detach the bottom one by disconnecting the bottom blue clip. 

Slide down the hose and take that out. As for the top hose which leads to the faucet, first pull out the metal clip straightly & slide down that hose. 

iii) Replace The Solenoid

That’s all done! Now you can separate the whole valve unit attached to the battery pack. 

Take your replacement valve body and install it under the sink in a reverse way, just as you detach the valve body. Hopefully, the blinking red light issue is resolved!
