1. Kohler Touchless Toilet Sensor Not Working
Obstructions that may stop the sensor from activating are the most probable reasons for the problem. Another problem is mounting cabinets or bars too close to the sensor, which may result in intermittent flushing, mainly if the cabinet doors keep opening.
Below are a few potential factors to watch out for if the sensor does not activate your touchless flush.
a) Installing The Tank Cover A Few Seconds Before Flushing
You should resolve this problem in five minutes after the unit has an automated adjustment.
Fix: Wait at least 15 seconds after your last flush before removing the tank lid.
b) The Touchless Module Is Set Too Low
Setting the sensor higher than two inches will inhibit your toilet’s functionality.
- Raise the component one notch at a time, testing the sensor with each step until it begins to function.
- Repeat this process until the detector range is 1 to 2 inches above the toilet tank lid. The sensor should be no higher than two inches above the tank cover.
If the procedures outlined above cannot correct the problem, purchase a module box lid or a new module box, then follow these steps:
- Remove the cover from the toilet tank, then take the chain link out of the module box.
- Take out the battery holder by opening the module box.
- Push the metal tabs up against the cover’s springs.
- The box is OK as long as the actuator wheel spins, but a new top is required. If it doesn’t spin, it signifies you have a broken box that needs replacement.
- Get the manufacturer-recommended spare component for the model and get a professional to install it.
2. Ghost Flushing
Ghost flushing happens when a flush happens without you initiating it or when the unit flushes without external activation. When the toilet refills, water from the flush valve spills on the Touchless component or underneath the tank lid.
- Insert the refill hose far enough into the flush valve.
- Realign the hose to reduce splashing.
3. Actuator Wheel Does Not Fully Rotate
Low batteries hinder the activating wheel from making complete rotation stations. The touchless component beeps five times before activating, signaling that the batteries are low.
Consider replacing the batteries and avoid using rechargeable ones.
4. Touchless Module Activating Early
The touchless module activates early when you lean back or when the toilet seat touches the tank lid. Additionally, a moving or a rocking toilet tank lid and objects above the tank cover will have a similar effect.
- Attach the foam pads (bought with the touchless module) to the tank top. Install the pads according to the instructions.
- Ensure there are no objects within 8 inches of the sensor.
- Shim the toilet bowl to keep it from moving.
- Use silicone sealant around the bowl’s base to keep it in place.
5. Kohler Touchless Toilet Leaks
Toilet leaks in these models are often associated with faulty vacuum breakers.
- If leakage occurs after a flush, use component 1192024 to replace the vacuum breaker unit.
- If the leakage persists after changing the vacuum breaker component, use Sloan valve VB6551A.
Why Does My Kohler Touchless Toilet Keep Flushing?
Here is why your touchless toilet keeps flushing and how to fix it.
a) The Water Level Rises Too Quickly
The water level rapidly rises when refilling and triggers the sensor.
Fix: To slow the filling rate, close the water supply partially.
b) Small Or Narrow Tank
A narrow tank fills faster than a bigger one.
Fix: Cut off the water supply partially to reduce the rate of refilling.
c) Water Splashing On The Touchless Module
It happens when you position the refill hose incorrectly.
- Insert the refill hose into the flush valve and reposition it to limit splashing.
- If you bought a Kohler touchless toilet with a canister valve, check the color of the cylinder cap.
- Replace the black cap (such as Highline or a retrofitted Wellworth) with the one in the canister repair kit K-GP1229656.
- Reduce the water supply to slow the refill rate and prevent splashing.
- Alternatively, buy a K-1219268 chain kit and allow the chain to dangle in the water from the mounting bracket. It lowers the sensor’s sensitivity to water in the tank.
d) Condensation From The Internal Tank Pouring Onto The Touchless Module
It is a prevalent issue in warmer areas with warmer water sources.
- Dry the touchless device and underneath the tank lid. Check that the tank cover is totally dry.
- Insert the foam pad kit K-1275758 to minimize condensation below the toilet lid.
Kohler Touchless Toilet Discontinued
The brand has discontinued Kohler K-3817-0, K-4000-47, and K-6419-0 because of installation difficulties and faults with their touchless modules. In their place, the company offers you K-4434, K-4380, K-4636, and K-1954 touchless toilet retrofit packages, among others.
They employ the Aquapiston single flush canister mechanism, which uses trapways, precision-engineered bowls and tanks, and gravity. This technology creates an efficient siphon while flushing.
Additionally, the alternative packages are ADA-compliant, WaterSense certified, and have a one-year warranty.
Kohler Touchless Toilet Beeps 3 Times
Your touchless toilet beeps three times because the actuator wheel fails to rotate completely. It signals low batteries.
The touchless unit would beep three times or more before activating. Get new batteries when this happens.
