Symptoms Probable Cause
Low flow (cont.) Digital Mixing Valve box failure.
Flow stops during showering 'Shower run time' setting is
enabled. Shower run time reduces
the shower run time to a user
defined time.
Outlet hose or handset blocked.
Combination boiler cutting in and
out (HP/Combi valve only) causing
blend temperature fluctuations.
Cold inlet water supply pressure
too low or fluctuating.
Cold inlet water supply failure.
Inlet filters or check valves
blocked.
Digital Mixing valve air locking.
Reversed inlet supplies.
Digital Mixing Valve box failure.
Showering temperature too cool Temperature adjustment on
interface set too low.
Inlet filters or check valves
blocked.
Outlet hose or handset blocked.
Reversed inlet supplies.
Hot inlet water supply temperature
is too cool.
Insufficient quantity of stored hot
water.
Inlet water supply pressures are
unstable or imbalanced.
Combination boiler cutting in and
out (HP/Combi valve only).
Outlet pipe run is too long.

Possible Remedy
Contact Customer Services.
No product fault, refer to 'using
the shower' in the user interface
manual or check the 'shower
duration' within the APP.
Check for correct installation
practices, repeat commissioning
procedure and rearrange pipework
to avoid airlock forming, refer to
'Typical Suitable Installations'.
Refer to 'Use of Flow Regulators'
for correct operation.
Ensure the water supply pressures
are stable and nominally equal,
refer to 'Specifications'.
Check and remedy.
Check and remedy, refer to
'Maintenance'.
Check for correct installation
practices, repeat commissioning
procedure and rearrange pipework
to avoid airlock forming, refer to
'Typical Suitable Installations'.
Check and remedy. This can be
reversed easily via the APP -
'Settings' screen - 'Outlet Setup'
screen.
Contact Customer Services.
Increase temperature by rotating
temperature indicator.
Check and remedy, refer to
'Maintenance'.
Check and remedy.
Check and remedy.
Increase hot inlet water
temperature to between 55°C and
65°C, refer to 'Specifications'.
Hot water supply running out,
increase storage capacity to
minimum 120 litres, refer to
'Specifications'.
Ensure the water supply pressures
are stable and nominally equal,
refer to 'Specifications'.
Refer to 'Use of Flow Regulators'
for correct operation.
Ensure outlet pipe work is
thermally lagged.
Symptoms Probable Cause
Showering temperature too cool Digital Mixing Valve box failure.
(cont).
Shower temperature too hot or Temperature adjustment on
fluctuates. Controller set too high.
Hot inlet water supply temperature
is too hot.
Inlet filters or check valves
blocked.
Combination boiler cutting in and
out (HP/Combi valve only) causing
blend temperature fluctuations.
Inlet water supply pressures are
unstable or imbalanced.
Shower temperature affected by
the use of adjacent hot/cold tap.
Insufficiently sized pipework to
feed both Digital Mixing Valve and
taps at the same time.
Digital Mixing Valve box or
Controller failure.
Internal leaking. Pumped Gravity LP valve fitted to a
HP/Combi water system.
Digital Mixing Valve box failure.
No shut off / continuous flow / Natural drain down of shower
shower fitting drain down. fittings.
Digital Mixing Valve box failure.
Noise. Digital Mixing Valve air locking.
Possible Remedy
Contact Customer Services.
Increase the temperature by
rotating the temperature indicator.
Reduce hot inlet water temperature
to between 55°C and 65°C, refer to
"Specifications".
Check and remedy, refer to
'Maintenance'.
Refer to "Use of Flow Regulators"
for correct operation.
Ensure the water supply pressures
are stable and nominally equal,
refer to 'Specifications'.
Increase pipe sizes or separately
feed shower, refer to 'Installation'
for correct plumbing method.
Contact Customer Services.
Pumped Gravity LP valves are
not suitable for connection to HP/
Combi water systems, refer to
"typical suitable installation".

No product fault. It is natural for
all shower outlets to continue to
expel water for a short period of
time after use. It is not uncommon
for larger deluge shower heads,
particularly those connected to
long outlet pipe runs and therefore
holding large volumes of water, to
drain down water several hours
after use due to the changes in the
ambient temperature. We would
therefore recommend that all water
outlets are kept enclosed within the
water catchment area.
