Delta Touch Faucet Troubleshooting Guide

Delta touch faucets offer a modern and convenient way to control water flow with just a simple touch. However, like any electronic device, they can occasionally run into issues. This guide will help you troubleshoot common problems such as Delta touch faucets not working after battery replacement, issues with blinking lights, and solenoid malfunctions.

Step-by-Step Troubleshooting for Delta Touch Faucets

1. Delta Touch Faucet Not Working After Battery Replacement

If your faucet stopped working after you replaced the batteries, there are a few possible causes:

• Check Battery Orientation. Ensure the batteries are correctly installed. If they’re positioned incorrectly, the faucet won’t receive power.
• Battery Type. Make sure you are using fresh AA alkaline batteries. Do not mix old and new batteries or use rechargeable batteries.
• Reconnect the Battery Pack. Ensure the battery pack is securely connected to the control box. A loose connection can prevent the faucet from functioning.
• Reset the Faucet. After replacing the batteries, perform a reset by disconnecting the power (batteries or AC adapter), waiting for 30 seconds, and reconnecting it.

2. How to Reset a Delta Touch Faucet (Reset Button)

Sometimes, a simple reset can fix many issues, such as an unresponsive faucet. Here’s how you can reset your Delta touch faucet:

• Turn Off the Water Supply. Shut off the water under the sink.
• Disconnect the Power. Remove the battery pack or disconnect the AC adapter if connected.
• Wait for 30 Seconds. Give the faucet time to reset its system.
• Reconnect the Power. Reattach the batteries or AC adapter securely.
• Turn the Water Back On. Check if the touch feature is working properly by turning the faucet on.

3. Delta Touch Faucet Not Working with Blue Light On

If your faucet’s blue light is on but it’s not responding to touch, follow these troubleshooting steps:

• Check Sensor Placement. Ensure that the faucet is not too close to metal objects or other surfaces, as these can interfere with the sensor.
• Grounding Issues. If you’re using an AC adapter, make sure the outlet is properly grounded and always powered on.
• Separate Wires. Ensure that sensor wires and battery wires are separated by at least 2 inches to prevent interference.
• Loose Connections. Double-check that all the connections under the sink are secure, especially the sensor wire and solenoid valve connections.

4. Delta Touch Faucet Blinking Red Light

A blinking red light typically signals low battery power, but there are other potential causes to check:

• Replace the Batteries. Replace the batteries with fresh AA alkaline batteries.
• Battery Corrosion. If your battery holder shows signs of corrosion, clean it before inserting new batteries.
• Solenoid Check. If the red light continues to blink after battery replacement, the solenoid may need to be replaced. You can also check for any pinched or damaged wires.

5. Delta Touch Faucet Manual Bypass

If your Delta touch faucet isn’t responding, you can switch it to manual mode and use it like a traditional faucet:

• Remove the Battery Pack. With the water running, disconnect the battery pack. The solenoid will remain open, allowing water to flow manually.
• Solenoid Removal (For Newer Models). For later models (post-2014), you can remove the solenoid entirely and connect the spray wand hose directly to the valve outlet tube.

Here’s how you can remove the solenoid assembly:

1. Disconnect the sensor wires from the spout and valve shank.
2. Remove the hose from the solenoid and detach the solenoid assembly.
3. Reconnect the hose to the valve outlet for manual operation.

6. Troubleshooting the Solenoid Valve

The solenoid valve plays a crucial role in controlling water flow. Here’s how to troubleshoot it:

• Check for Loose Connections. Ensure the solenoid valve is securely connected to both the control box and battery pack.
• Insulation Issues. If your faucet is installed on a metal or granite sink, ensure there is proper insulation around the faucet shank, and that the shank is at least ½ inch clear of the sink’s edge to prevent interference with the sensor.
• Low Water Flow. If the solenoid is clogged with debris or mineral deposits, clean it using a vinegar solution.
• Ghosting or False Activation. If the faucet turns on randomly, try replacing the solenoid with the latest version, especially if it activates when other appliances are running.
