Why Won't My Kohler Smart Toilet Bidet Nozzle Retract?

Device: Kohler Intelligent Toilet (Numi 2.0, Veil Intelligent, K-5401, K-8298)

The bidet wand or nozzle on your Kohler intelligent toilet extends for cleansing but does not retract back inside the housing after the cycle completes. The nozzle remains extended and exposed, which prevents the lid from closing fully. This is caused by a mechanical jam, a water pressure issue preventing the retraction mechanism from engaging, or the control electronics entering a fault state.

Why Is My Kohler Touchless Faucet Not Turning On Automatically

Device: Kohler Touchless Faucet (Kohler Sensate, Kohler Setra, Kohler Malleco Touchless)

Your Kohler touchless kitchen or bathroom faucet sensor fails to activate when you wave your hand near it. The sensor may be completely unresponsive, require multiple attempts before activating, or randomly activate without anyone near the spout. Sensor failures in Kohler touchless faucets are primarily caused by low batteries, ambient IR interference, or a dirty sensor window — not hardware defects.

Why Is My Kohler Smart Toilet Not Flushing Automatically

Device: Kohler Intelligent Toilet (Kohler Numi 2.0, Kohler Veil, Kohler Eir)

Your Kohler smart toilet does not flush automatically when you leave the seat, or automatic flushing activates at random times without use. Automatic flushing in Kohler smart toilets uses an infrared proximity sensor to detect presence and departure — false triggers and missed flushes are both caused by sensor calibration, battery level, or obstructions in the sensor field.

Kohler PureWash Bidet Seat Not Heating Water or Seat — Troubleshooting Guide

Device: Kohler PureWash E930 / E925 / E815 Bidet Seat (PureWash E930, E925, E815, C3-230)

Your Kohler PureWash bidet seat does not produce warm water during use, the heated seat surface remains cold at all temperature settings, the remote control does not trigger any functions, or features like the night light and warm air dryer have stopped working. The PureWash requires a dedicated electrical outlet and a properly primed water supply line — most multi-feature failures trace back to a power interruption or the water inlet filter being blocked.

Why Is My Kohler Konnect Faucet Not Dispensing Water?

Why Is My Kohler Touchless Faucet Running Water Continuously and Won't Shut Off

Device: Kohler Touchless Faucet (Kohler Sensate, Kohler Barossa, Kohler Malleco, Kohler Setra Touchless)

Your Kohler touchless kitchen or bathroom faucet is running water continuously and will not shut off when you move your hands away from the sensor. The water keeps flowing regardless of hand proximity to the sensor zone. You may need to turn off the water supply valve under the sink to stop the flow.

Why Won't My Kohler DTV+ Digital Shower Start from the App After It Was Working Before

Device: Kohler DTV+ Digital Shower (DTV+, K-99693, K-99694, DTV Mode, DTV Prompt)

Your Kohler DTV+ digital shower system was previously working with the Kohler Konnect app but now refuses to start when you send a command from your phone. The physical interface on the shower still works to start and control water but app commands are ignored. You may see the app connect to the system but start commands do not activate the shower.

Why Won't the Kohler Konnect App Connect to My Smart Device?

Device: Kohler Konnect Smart Products (Numi 2.0, DTV+ Shower, Veil, K-99100, K-8298)

The Kohler Konnect app cannot find or connect to your Kohler smart toilet, shower, or bathroom device during setup or after a router change. The app searches but times out, or the device shows as offline after initial setup. Kohler Konnect devices require 2.4GHz WiFi and the app needs precise Bluetooth proximity during the initial provisioning handshake before switching to WiFi operation.

How to Fix Kohler Touchless Faucet That Stops Working or Drips

Device: Kohler Sensate / Setra Touchless Faucet (Sensate K-72218, Setra K-87014, Malleco K-562)

Your Kohler Touchless faucet sensor stops responding to hand waves, activates randomly on its own, drips when it should be off, or the battery depletes unusually fast. Touchless kitchen and bathroom faucets use infrared sensors that are sensitive to ambient IR sources, reflective surfaces near the spout, and battery voltage. Most sensor failures clear with a power cycle or battery replacement — hardware failure is uncommon before the 5-year mark.

Why Does My Kohler Sensate Faucet Keep Dripping After Being Activated?

Device: Kohler Sensate Touchless Faucet (Kohler Sensate, K-72218, K-72219, K-72220)

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.

How Do I Set Up Shower Presets on My Kohler Konnect DTV+?

Device: Kohler Konnect DTV+ (All Models)

You want to create and save shower presets on your Kohler DTV+ digital shower system so you can start your preferred shower with one tap. Presets store your temperature, water volume, and spray pattern settings. This guide covers creating presets on the DTV+ controller touchscreen and through the Kohler Konnect app.

Why Does My Kohler Sensate Touchless Faucet Turn On Without Hands Near It

Device: Kohler Sensate Touchless Faucet (Sensate, K-72218, K-560, Response Touchless)

Your Kohler Sensate touchless kitchen faucet randomly turns on when nobody is near the sink. Water starts flowing on its own, wasting water and causing surprise. The sensor seems to detect phantom motion or trigger from environmental factors. This wastes water and is unsettling.

Why Does My Kohler DTV+ Shower System Keep Disconnecting From WiFi

Device: Kohler DTV+ Shower System (Kohler DTV+ K-99695, K-99696, K-99697, DTV+ Interface, DTV Mode)

Your Kohler DTV+ digital shower controller loses WiFi connection overnight or intermittently throughout the day. The app shows the shower offline, and you cannot start presets remotely. The controller continues to work locally but remote access and voice control through the Kohler Konnect app fail.

Why Is My Kohler Konnect Faucet Constantly Dripping?

Device: Kohler Konnect Faucet (Sensate, Setra, Components)

Your Kohler Konnect smart faucet drips continuously from the spout even after being shut off through the app or the manual touchless sensor. The drip persists regardless of whether the water was closed remotely or physically. Constant dripping from a Kohler Konnect faucet after closure indicates a solenoid valve that is not fully closing — caused by mineral scale debris caught in the valve seat or a solenoid coil that is not receiving a full shutdown signal.

How Do I Adjust the Kohler Sensate Touchless Faucet Sensor?

Device: Kohler Sensate (All Models)

You want to adjust the sensor sensitivity on your Kohler Sensate touchless kitchen faucet. The Sensate has two sensors: a ready sensor that detects hands near the spout and a wave sensor that activates with a hand swipe above the faucet. Both sensors can be adjusted for sensitivity using the control box mounted under the sink.

Why Won't My Kohler Konnect Shower Turn On or Respond to Voice Commands?

Device: Kohler DTV+ / Konnect Smart Shower System (DTV+, Anthem, Konnect-enabled valves)

Your Kohler Konnect digital shower system will not start from the Kohler Konnect app, does not respond to Alexa or Google Home voice commands, or the digital valve shows as offline in the app. The Konnect system communicates through a digital interface module that requires a stable home network connection — connectivity issues and API authentication failures are the most common causes of unresponsive controls.

How Do I Fix My Kohler Konnect Faucet"s Temperature Not Changing?

Device: Kohler Konnect Faucet (Sensate, Setra, Components)

Your Kohler Konnect smart faucet is dispensing water at a fixed temperature, or the temperature is not changing as expected when adjusted via the app, voice, or manual handle. This prevents precise temperature control.

Why Won't My Kohler DTV Shower Preset Temperature Save?

Device: Kohler DTV Prompt Smart Shower (Kohler DTV Prompt, K-99700, K-99701, DTV+ Shower)

Your Kohler DTV shower controller will not save the custom temperature preset for your personal shower profile. Every time you return to the preset the temperature defaults back to a previous value or to the factory default. The preset save procedure requires a specific sequence of holding the temperature controls and is frequently not completed fully, causing the changes to revert when the shower turns off.

Why Is My Kohler Konnect Faucet Not Connecting to Wi-Fi?

Device: Kohler Konnect Faucet (Sensate, Setra, Components)

Your Kohler Konnect smart faucet is failing to connect to your home Wi-Fi network, preventing access to smart features, voice control, and app-based settings. This often manifests as a blinking or red LED on the control box.

Why Does My Kohler Sensate Show Low Battery After Replacing Batteries

Device: Kohler Sensate Touchless Faucet (Sensate K-72218, Sensate K-72218-CP)

Your Kohler Sensate faucet still reports low battery even after installing a new set, and touchless behavior may become delayed or inconsistent. This causes repeated alerts and unreliable activation. The issue is usually tied to mixed battery chemistry, poor terminal contact, moisture in the battery box, or battery status cache not refreshing after replacement.

Why Isn't My Kohler Numi 2.0 Seat Heater Getting Warm?

Device: Kohler Numi 2.0 Intelligent Toilet (Kohler Numi 2.0, K-5401, K-5402)

Your Kohler Numi 2.0 intelligent toilet seat heater is not warming up even though it is turned on and set to a heating level in the Kohler Konnect app. The seat remains cold regardless of the selected heat setting. Seat heater failures are caused by the occupancy sensor not detecting a user which prevents heating from activating, the energy saving mode disabling the heater after a period without use, or the heating element having a fault that requires a reset.
