Symptom Possible cause Action
Controller LEDs
flashing and changing
colour when power
turned on to the
Aqualisa SmartValveTM
Start up sequence
and controller
configuration in
process
No action required - sequence and
configuration can last up to 2 minutes. Wait
until LEDs go out and then the controller is
ready to use.
Controller
unresponsive -
No Lights / Blank
Power supply turned
o to Aqualisa
SmartValveTM
Check power supply is turned on - Green power
light should be illuminated on the Aqualisa
SmartValveTM.
Loss of
communications
Check data cable connections are making good
contact and are fully inserted and that there is
no visible damage.
Check that the wiring schematics are as
per installation instructions in the Smart
Installation Guide.
Pump noisy and low
/ no flow
Air lock (for Gravity
fed systems only)
For models utilising a adjustable head kit;
disconnect the handset from the hose, see Head
section on page 7, lower the hose into the shower
tray or bath and then start the shower. Set the
temperature to fully cold and as the water starts
to flow and increase in volume, gradually turn up
the temperature. If the flow starts to splutter, stop
moving the temperature control until the flow again
stabilises, then continue to move the bezel towards
the hottest setting.
Restriction in the
waterway
Check for debris in the inlet filters of the
Aqualisa SmartValveTM, diverter and Fixed Head
connection washer. Must be conducted by a
qualified person. NOTE: The water supplies
MUST be isolated when checking the inlet filters.
Blocked or kinked
hose liner
Where a flexible hose is fitted, unscrew the
shower hose from the outlet connection and
turn the shower on.
Low / no flow Seasonal conditions During the cooler months the mains water
temperature drops and this will reduce the
performance of combination boilers. Check
with your boiler manufacturer for details.
Incorrect Aqualisa
SmartValveTM fitted
If water supplies are gravity fed, the PUMPED
Aqualisa SmartValveTM must be used (unless a
separate stand alone pump is being utilised).
Refer to the Smart Installation Guide.
Water supply issue For the Standard Aqualisa SmartValveTM - Ensure
water is turned fully on at the mains and at the
servicing valve in the supply.
Ensure isolation valves are fully open.
Low / no flow
(continued)
Restriction in the
waterway
See same cause in 'Pump noisy and low / no
flow' symptom.
Blocked or kinked
hose liner
Where a flexible hose is fitted, unscrew the
shower hose from the outlet connection and
turn the shower on.
Incoming mains water
pressure or flow too low
(Standard Aqualisa
SmartValveTM only)
After confirming that the filters are clear, check
with the local water authority.
Separate, stand
alone pump
not activating
(Standard Aqualisa
SmartValveTM only)
Ensure sucient flow to activate the
flow switches of the pump. Refer to
IMPORTANT INFORMATION section in
the Smart Installation Guide.
Aqualisa
SmartValveTM pump
not activating
Refer to Setting Water System Mode section in
the Smart Installation Guide, ensure mode is set
to normal or ECO gravity setting.
Shower head or
Aqualisa SmartValveTM
is set to ECO mode
Refer to page 6 of this guide and to the above
point.
Unable to adjust or
control temperature
Reversed inlet water
supplies (i.e. Hot
supply feeding cold
inlet and vice-versa)
Ensure correct water supply to specified inlet
connection of the Aqualisa SmartValveTM.
Fluctuating water
temperature
Incorrect setting
on Logic Module
of Aqualisa
SmartValveTM
If hot water supply is from a combination
boiler- the Logic module mode MUST be set to
COMBI. Refer to Setting Water System Mode
section in the Smart Installation Guide.
Airlock in water
supplies (for gravity
fed systems only)
See “Air lock” in Possible Cause section on
page 12.
Hot water
temperature too high
Ensure hot water supply temperature is below
65ºC 55ºC (minimum 55ºC for stored water
and 50ºC for combination boilers).
Communications issue Check data cable connections and that there is
no visible damage.
Combination boiler
unable to meet
demand
Check if another outlet in the property is being
used at the same time.
Check that the hot water temperature is stable
at another high flowing outlet (e.g. bath hot tap
- run at maximum flow rate), additionally run a
cold outlet at 1/3 of a maximum flow rate. If the
same issue is evident on these outlets, contact
your boiler manufacturer.
Temperature
too low
Low hot water
temperature
Check that domestic hot water temperature
is a minimum of 55ºC for stored water and
50ºC for combination boilers.
Logic Module
temperature setting
too low
Maximum temperature is set to a factory
default of 45ºC. To adjust refer to the important
information section (Safety Information) and
Controller Commission Instructions in the Smart
Installation Guide.
