Fault Diagnosis - Mira Platinum Installation And User Manual

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 digital mixing 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 make sure that the underlying cause of the malfunction has been resolved.
Warning! 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 Mira Showers app
(see section "Set Up: Mobile App").
Please follow this self-diagnosis section to be sure the product is at fault before contacting Mira.
