Why Is My Kohler Konnect Faucet Not Dispensing Water?

Problem Description

Your Kohler Konnect smart faucet is not dispensing water when activated by touch, motion, or voice commands, even though power is connected. This prevents basic faucet functionality and smart features.

Why This Happens in Real Homes

A Kohler Konnect faucet that won't dispense water at all - not by touch, motion, or voice - while the manual handle still works points to the electronic flow path being dead: either no power or a solenoid that won't open. Start with power, especially if the problem began after an outage. The faucet runs on a 6-AA pack in the under-sink control box, and a fully drained or disconnected pack leaves the sensor and solenoid inert. Install fresh cells, reseat the connector, and do a 30-second battery-out reset to clear any glitch the outage caused.

If power checks out, work down the flow path. The under-sink supply valves are the easiest thing to overlook - if one got bumped closed, no amount of sensing will produce water, and the fix is simply reopening them. Next is the solenoid valve: if it clicks but nothing flows, it's stuck closed and can sometimes be freed, or debris may be blocking it or the aerator. WiFi only matters for app and voice control, so a faucet that's offline in the app but works on touch has a network issue, not a water issue. Reserve a Kohler service call for a solenoid or control module that stays dead after fresh power, open supplies, and a reset.

Symptoms

• No water flow on touch, motion, or voice
• LED indicator off or red
• Faucet unresponsive to all inputs
• Manual handle still delivers water
• App shows the faucet offline
• Started after a power outage
• Solenoid clicks but no water comes
• Weak trickle instead of full flow

Recognize these? Here's what usually causes it.

Common Causes

• Power interruption or dead 6 AA battery pack
• Solenoid valve stuck closed or failed
• Sensor malfunction not signaling the valve
• WiFi disconnection affecting app/voice control
• Firmware glitch after an outage
• Water supply valve closed or partially shut
• Battery connector unseated or contacts corroded
• Debris blocking the valve or aerator

Tools & Requirements

Step-by-Step Solution

1

Check Power Supply

Make sure the control box (usually under the sink) is plugged into a working outlet and receiving power. Check for tripped GFCI outlets. If the outlet is controlled by a wall switch, make sure the switch is in the ON position.

2

Power Cycle the Faucet

Unplug the control box from power for at least 30 seconds, then plug it back in. Allow a few minutes for the control box to reboot and re-establish its connection. This can resolve temporary electronic glitches affecting water dispensing.

3

Verify Water Supply

Make sure both the hot and cold water supply valves under the sink are fully open. Also, check if the main water supply to your house is turned on. Sometimes, a partially closed valve can restrict water flow.

4

Inspect Solenoid Valve

Locate the solenoid valve on the control box (it"s typically a cylindrical component with wires). When you activate the faucet (e.g., by waving your hand), listen closely for a faint click from the solenoid. If you don"t hear a click, the solenoid might be faulty or not receiving power.

5

Check for Obstructions or Kinks

Inspect the water lines leading to and from the control box for any kinks, bends, or obstructions that could restrict water flow. Make sure the spray head is not clogged; try removing it and testing the flow directly from the hose.
