Why Does My Kohler Sensate Faucet Keep Dripping After Being Activated?
- Solenoid valve not fully closing due to debris in valve seat
- Sensor sensitivity too high causing it to detect ambient movement
- Solenoid coil in fault state requiring power reset
Problem Description
Your Kohler Sensate touchless kitchen faucet drips or runs continuously after a wave activation ends, even when no hands are near the sensor. The faucet should shut off within 2 seconds of the wave gesture being completed but instead water continues to flow or drip after the sensing event. This is caused by the solenoid valve not fully closing, sensor sensitivity detecting background motion, or the solenoid coil needing a power reset.
Symptoms
- Faucet drips continuously after activating with a hand wave
- Water keeps flowing for 30 seconds or more after hand is removed
- Faucet activates then never shuts off without turning handle manually
- Drip persists at a slow rate even hours after last intentional use
- Sensor light blinks as if sensing motion even when sink is empty
- Faucet began dripping after a low water pressure event
Recognize these? Here's what usually causes it.
Common Causes
- Solenoid valve not fully closing due to debris in valve seat
- Sensor sensitivity too high causing it to detect ambient movement
- Solenoid coil in fault state requiring power reset
- Low water pressure during previous activation leaving valve partially open
- Soap or grease buildup on sensor window causing phantom sensing
- Valve seal worn from high-mineral-content water causing drip
Most fixes happen in the first 3 steps.
Do not attempt to disassemble the Kohler Sensate solenoid valve yourself. The solenoid assembly is a sealed unit and user disassembly voids the faucet warranty. Contact Kohler support for solenoid replacement.

Step-by-Step Solution
Power Cycle the Faucet Solenoid
Turn off both the hot and cold supply valves under the sink. Wait 30 seconds for the solenoid to fully de-energise and any residual water pressure to equalise. Slowly turn the supply valves back on. The solenoid will reset to its default closed position on power restoration. Test the faucet by waving your hand in front of the sensor to activate it then removing your hand. The water should stop within 2 seconds. If the drip continues after power cycling the solenoid seal may be worn.
Clean the Sensor Window
The Sensate faucet sensor is located on the neck of the faucet behind a small window. Soap residue, hard water scale, and cooking grease can accumulate on this window causing the sensor to register phantom activations and keep the solenoid open after use. Wipe the sensor window firmly with a clean damp cloth. Use a small amount of white vinegar to dissolve mineral deposits if present. After cleaning the sensor window dry it completely before testing touch-free activation.

$13.99Adjust Sensor Sensitivity
The Kohler Sensate has a sensitivity adjustment button located under the sink on the solenoid control box or on the faucet base depending on the model. Press the adjustment button once to reduce the sensor range by approximately 25 percent. A shorter detection range reduces false activations from passing objects and kitchen activity that can keep the solenoid open. After adjusting test by waving at the normal distance and verifying the faucet turns off promptly.
Flush the Valve Seat
Debris caught in the solenoid valve seat can prevent it from fully closing causing a continuous drip. To flush the valve turn the faucet on manually using the handle and run cold water at full pressure for 30 seconds. Then turn the handle off and immediately activate the touch sensor three times in quick succession. This rapid cycling can dislodge debris from the valve seat. If the drip reduces or stops after this flush the valve seat was partially blocked.
Check Water Pressure Range
Kohler Sensate solenoids are rated for water pressure between 20 and 125 psi. Pressure above 125 psi can force the solenoid valve partially open when it tries to close resulting in a continuous drip. Install a pressure gauge on the faucet supply line to measure inlet pressure. If pressure exceeds 80 psi install a pressure reducing valve on the supply line. Reducing pressure to 60 to 70 psi allows the solenoid to close fully and eliminates pressure-induced dripping.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If this comes back after following these steps, check whether a recent app or firmware update reset a default setting — the fix works, but the setting gets reverted silently.
Use the Kohler Konnect app to monitor daily water usage from the Sensate faucet. A sudden spike in reported water volume without corresponding use is the first indicator of a dripping solenoid valve.
Battery-related failures are almost always flagged too late — the device degrades silently for days before the app catches up to what's actually happening.
- Solenoid valve not fully closing
- Sensor sensitivity too high
- Solenoid coil in fault state requiring power reset
- Low water pressure during previous activation
- Soap or grease buildup on sensor window
