2. Fault Diagnosis – Installer Maintenance
The Mira Extreme is one part of an entire plumbing system. The fitting of a pump places
additional requirements on the plumbing system. Some systems may require plumbing
modifications to allow them to cope with higher flow rates.
Providing the Mira Extreme has been correctly installed and is operated as advised,
difficulties should not arise. Fault diagnosis and maintenance must be carried out by
a competent person for whom the fault diagnosis table is provided.
In the event of any of the following tests failing, re-check as appropriate before
contacting the Kohler Mira Customer Support Department (refer to
Back Cover ).

Malfunction Cause Remedy
Shower runs for a
short time (30-60
seconds) then flow
reduces, splutters or
stops. Aggravated
when other hot taps
are in use. Less
evident on full cold. Air is being sucked
down the vent pipe, as
the hot take off to the
shower is too high up
the pipe. Refer to plumbing system diagrams
in the section "
Installation Re-
quirements " for correct connec-
tion method. Note the 1 metre hot
take-off dimension. Consider in-
creasing cold feed pipe to cylinder
to 28mm diameter.
Shower runs cool af-
ter a short time (1–2
minutes) then flow
splutters. Air ingress into hot
pipework. Refer to plumbing system diagrams
in the section "
Installation Re-
quirements " for correct connec-
tion method.
