Problem Description

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.

Symptoms

  • App shows connected but Start button does nothing
  • Shower worked from app previously but stopped
  • Physical shower controls work fine
  • App commands have several second delay then fail
  • Presets saved in app no longer activate shower
  • Voice commands through Alexa also fail to start shower

Recognize these? Here's what usually causes it.

Common Causes

  • WiFi module in shower system lost connection
  • Kohler cloud authentication token expired
  • Router changed IP address of shower system
  • App needs re-authorization to shower controller
  • Shower system firmware needs update
  • Water heater not providing hot water causing safety cutoff

Most fixes happen in the first 3 steps.

Warning

Never attempt to access the DTV+ controller electronics while the system is wet or powered on. Water and electricity are a dangerous combination. If you are not comfortable working with electrical systems or plumbing, contact a licensed professional or Kohler authorized service technician. Incorrect troubleshooting can cause electrical shock or damage the system.

Step-by-Step Solution

1

Power Cycle the DTV+ System

Locate the circuit breaker that controls your DTV+ shower system. Turn it off and wait 60 seconds. Turn it back on and wait 2 minutes for the system to fully boot and reconnect to WiFi. The shower controller needs time to re-establish its cloud connection after a power cycle.

2

Check WiFi Connection Status

On the DTV+ interface panel in your shower, navigate to Settings and then Network. Verify that the system shows connected to your WiFi network with a valid IP address. If it shows disconnected or has an IP starting with 169.254, the WiFi connection was lost and needs to be reconfigured.

3

Re-Link Shower in Kohler App

Open the Kohler Konnect app and go to your DTV+ device. Select the gear icon for settings and choose Unlink Device. Confirm removal. Then go through the Add Device process again to re-pair your phone with the shower system. This refreshes the authentication tokens.

4

Verify Hot Water Availability

The DTV+ system has a safety feature that prevents starting if the water heater cannot provide adequate hot water. Run hot water from another faucet to ensure your water heater is working. If you have a tankless heater, verify it is powered on and has gas or electricity supply.

Update System Firmware

In the Kohler Konnect app, check if a firmware update is available for your DTV+ system. Updates often fix connectivity bugs. If an update is available, apply it when you will not need to use the shower for at least 30 minutes as the update process interrupts operation.

Quick Solutions

Power cycle the DTV+ system at breaker
Re-link shower in Kohler Konnect app
Check that shower system is on same network as phone
Verify hot water supply is available
Update DTV+ firmware if available
Reset WiFi module on shower controller

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.

Pro Tip

Create a DHCP reservation in your router for the DTV+ system to ensure it always gets the same IP address. This prevents connection issues when the router assigns a different address.

Real-World Insight

This issue almost always looks more complex than it is — the majority of cases trace back to a single setting, a stale credential, or a default that shipped wrong.

What Usually Goes Wrong
  • WiFi module in shower system lost connection
  • Kohler cloud authentication token expired
  • Router changed IP address of shower system
  • App needs re-authorization to shower controller
  • Shower system firmware needs update
