Troubleshooting
Fault Diagnosis
Read the section “Important Safety Information” first. As with most electronic equipment resetting the digital mixing
valve by powering it down waiting a few seconds then powering it up again can often cure most issues.
Providing the KOHLER Digital Valve has been correctly installed and is operated in accordance with the instructions
contained in this guide, difficulties should not arise. If any maintenance is required, then it must be carried out by a
competent tradesperson. Before replacing any parts, verify that the underlying cause of the malfunction has been
resolved.
IMPORTANT! There are no user serviceable components beneath the cover of the appliance. Only a competent
tradesperson should remove the cover.
The digital mixing valve has built-in sensors to help diagnose system and product issues. To access these advanced
diagnostics features, please download the KOHLER Konnect app (see Homeowners Guide).
Please follow this self-diagnosis section to verify that the product is at fault before contacting Customer Service.
Diagnosis stage 1 (Error code check):
In the first instance, check that your product has no error warning displayed on the controller. You can also check for error
codes on the KOHLER Konnect app.
Only some errors are displayed on the controller. You will need to download the KOHLER Konnect app for full diagnosis
and error functionality.
If you have an error code not listed below, or if the errors continue to occur after it has been reset, please contact Customer
Service to resolve the issue.
If you do not have an error code, proceed to Diagnosis stage 2.
