Mira GO 8.5 Installation, Operation, Maintenance Manual page 31

Malfunction
Appliance fails to
produce hot water
in any switch
position.
Shower cycles
hot and cold.
Cause
Electrical supply isolated
at double pole switch (the
pull-cord).
Fuse 'blown' or MCB/RCD
tripped - indicating an
electrical fault e.g. heater
tank element failure.
Insufficient water supply
pressure.
Possible failure of the
microswitch or thermal
switch.
Poor internal wire
connections.
The temperature is set to
an unsafe level. To protect
the appliance, a fixed
temperature thermal switch
is incorporated that cuts
the power to the heater
tank at too high a
temperature.
Handset spray plate
blocked.
Remedy
Switch on.
Correct the fault and
renew the fuse or reset
the MCB/RCD.
Renew the heater tank.
Contact local water
authority/undertaker.
Use a suitable continuity
measuring device to
check the continuity of
the microswitches or
thermal switch and
renew parts as
necessary.
Check integrity of
internal wiring.
Turn the temperature
knob sufficiently
anticlockwise to
increase the water flow
and prevent operation of
the thermal switch. DO
NOT tamper with the
thermal switch.
Remove and clean/
replace, refer to
Maintenance in the
shower fittings I,O & M
guide.
