Kohler Touchless Faucet Not Working: Full Troubleshooting Guide

Kohler touchless faucets are a convenient and hygienic option for your kitchen or bathroom. However, just like any other faucet, they can experience issues affecting their performance. If you’re facing problems with your Kohler touchless faucet, don’t worry; there are a few simple steps to troubleshoot the issue.

The Kohler Touchless faucet is not working at all

Check the Power Source

The first step in troubleshooting your Kohler touchless faucet is to check the power source. If your faucet is powered by an AC adapter, make sure it is plugged into an unswitched outlet. And, If your faucet is battery-operated, check that the batteries are not low or old. If necessary, replace them with new batteries.

Clean the Sensor

Over time, mineral deposits and other debris can build up on the sensor lens and sensor wire connector, which can affect the touchless function. To clean the sensor, use a toothbrush or small brush to remove any debris that may have accumulated. You can also use a mild soap and water solution to clean the sensor if necessary.

Tighten Loose Connections

Check for any loose connections and tighten them if necessary. Loose connections can cause issues with the touchless function. Be sure to check all connections, including those on the faucet body, control box, and battery compartment.

Turn the Spout Away from Steam

If your touchless faucet is located near a steam source, such as a dishwasher or coffee maker, turn the spout away from the steam. This can cause false activations of the touchless feature.

Disengage Manual Override

If your touchless faucet is in manual override mode, disengage it to ensure that the touchless function is working properly. Refer to the owner’s manual for instructions on how to do this.

Check Water Supply

Check the water supply to ensure it is not interrupted and the water pressure is sufficient. Low water pressure can affect the touchless sensor of the faucet. Ensure the water supply valves are open and there are no leaks or clogs in the water supply lines. Read more in detail on how to fix low water pressure

Replace the Sensor Assembly

If the issue persists, consider replacing the sensor assembly. Faulty wiring or a damaged sensor can cause issues with the touchless function. You can find replacement parts on the Kohler website or by contacting their customer service department.

Kohler Touchless Faucet is Leaking

If you notice that your Kohler touchless faucet is leaking, it can be frustrating and wasteful. However, you can identify and fix the issue with a little troubleshooting. Here are the steps to follow:

Check the Cartridge

The cartridge is responsible for controlling the water flow in the faucet. If it is damaged or worn out, it can cause leaks. Turn off the water supply valves and remove the faucet handle. Check the cartridge for any cracks, debris, or mineral buildup. If there is damage, replace the cartridge with a new one.

Check the O-rings

O-rings are small rubber rings that seal the different components of the faucet. If they are worn out or damaged, they can cause leaks. Check the O-rings around the base of the spout and the valve body. If they are damaged, replace them with new ones.

Check the Manual Override

If your touchless faucet has a manual override mode, make sure it is not engaged. This mode is designed to allow you to use the faucet as a regular faucet. If it is engaged, it can cause leaks. Refer to the owner’s manual for instructions on disengaging the manual override.

Check the Aerator

The aerator is the small screen at the end of the faucet spout. If it is clogged or damaged, it can cause leaks. Remove the aerator and clean it with mild soap and water. If it is damaged, replace it with a new one.

A leaking Kohler touchless faucet can be an easy fix with a little troubleshooting. Following these steps, you can identify and fix the issue, ensuring that your touchless faucet is working properly.

Kohler Touchless Faucet is Making Noise

Kohler touchless faucets may produce noise for different reasons, such as the presence of debris on the sensor, the detection of steam by the sensor, or restricted water flow resulting from a washer that is either the wrong size or not properly attached to the stem.

How to Fix it

Start by checking the aerator for any debris or buildup that might be obstructing the water flow.

To do this, turn off the faucet or water supply and carefully remove the aerator. Soak it in hot vinegar for a little while and brush the screen to clear any blockage.

If the noise persists, try tightening or replacing the washer. Sometimes, a faulty washer can cause unwanted noise in the faucet.

If this doesn’t work, inspect the washer seat for any residue that might be partially closing it. If there is any residue, clean it to remove the restriction and restore normal water flow, thus eliminating any whistling or chattering.

If you’ve tried all these steps and the noise persists, it’s likely that the issue is with the solenoid valve. Check if there is a clicking sound coming from the pilot valve. If so, it’s most likely a problem with the membrane in the solenoid valve. In this case, cleaning or solenoid replacement valve should solve the issue.

Finally, if the solenoid valve is worn out, it may not push or pull as effectively as it should, causing unwanted noise. If this is the case, you may need to reset or replace the solenoid valve.

With these steps, you should be able to eliminate any unwanted noise and enjoy a quiet and functional Kohler touchless faucet.

Kohler Touchless Faucet Water Temperature is Not Right

If you have a Kohler touchless faucet and the water temperature is not right, there could be several reasons for this issue. One common problem is with the water flow; either it’s not flowing or not stopping, which may be caused by a malfunctioning membrane or valve.

Another possible reason is that the motion sensor in your Kohler touchless kitchen faucet may not be working correctly, which could be due to debris on the sensor, steam interfering with the sensor’s functionality or an issue with the AC power adapter.

How to fix it

First, shut off the cold and hot water valves underneath the sink. This will ensure that water does not flow while you’re making adjustments. Then, remove the handle using an Allen wrench. You should be able to access the control box underneath the handle.

Locate the part that controls the temperature limit and rotate it clockwise. This will move the limit tab, allowing the faucet handle to turn further to hot. Adjust the handle to the desired water temperature.

It’s important to note that this process may vary depending on the model number of your Kohler faucet. Be sure to consult the owner’s manual for specific instructions.

Additionally, if you encounter any issues with the sensor lens or battery pack, you may need to replace the batteries.

By following these steps, you can ensure that your faucet is working properly and that you have the right water temperature for your needs.

Kohler Touchless Faucet Low water pressure

If you’re experiencing low water pressure with your Kohler touchless faucet, there are a few potential causes to consider. One common culprit is mineral buildup within the faucet’s aerator, which can significantly restrict water flow.

How to fix it 

Start by checking the spray head for mineral buildup, which may be causing restricted water flow. If this is the case, remove the spray head and check the flow from the hose. If the pressure is still poor, proceed to the next step.

Next, flush the supply lines to remove any debris or dirt that may be obstructing the water flow. You should also check the inlet screen for any debris that may be blocking the water flow.

If the water pressure is still low, check the mixed supply hose for kinks or other obstructions that may be restricting water flow. If you find any obstructions, clear them out to improve water pressure.

Finally, if none of the above steps work, you may need to replace the valve/cartridge if it is damaged or worn out.

By following these steps, you should be able to improve the water pressure of your Kohler touchless faucet and enjoy its full functionality. Read more in detail on How to fix it Low water pressure
