Water Dripping From The Spout End; Water Flow Rate / Stream Quality - PROBOIL .4E User's Installation Manual

1.3.3 Water dripping from the spout end:

Issue description:
Water is dripping (continuously
from the centre channel of the
spout end aerator).
Water is dripping (continuously
from the outer channel of the
spout end aerator).
Water is dripping (intermittently
from the centre channel of the
spout end aerator).
Most typically whilst the boiler is
reheating
Water is dripping (intermittently
from the centre or outer channel
of the spout end aerator typically
shortly after each use).

1.3.4 Water flow rate / stream quality:

Issue description:
98°C Water flow rate is slower
than expected.
Note: the typical flow rate is
between approximately
between 1 and 2 litres per
minute depending on your
incoming cold water pressure
and tap type, refer to the tap
specification sheet for more
detail.
No heated water is dispensed
when the Hotkey is placed near
the tap.

Possible issue & solutions:
The hot water on/off solenoid valve is leaking, to confirm the fault:
1) Turn the boiler into standby mode, press and hold the
seconds to activate.
2) run the 98°C water by placing the Hotkey on the tap for 5 minutes
3) Remove the Hotkey, If the water continues to continuously drip or leak
in large amounts the hot water solenoid valve may be faulty, call the
service number.
The standard hot and or cold water on/off valve is leaking, to confirm the fault:
1) Isolate the hot and or cold water supplies leading to the tap in turn, to
see if the dripping stops or not.
The expansion chamber in the boiler may be full:
1) Turn the boiler target temperature to 75°
2) Turn on the boiled water using the Hotkey, run for at least 4 litres
continuously to self-empty the expansion chamber.
3) Return the temperature back to 98°C
If the incoming cold water pressure is less than 1.5 bar, at low pressures the
expansion chamber will not self empty correctly, use a pressure gauge or use
the tap specific flow test on cold water only to confirm the incoming pressure.
This is water retained within the spout falling due to gravity and is normal for
any tap.
Possible issue & solutions:
The boiler could be calcified: follow the boiler descale procedure in this manual.
Your incoming cold water pressure could be too low: test your incoming cold
water pressure and compare it to the minimum required pressure.
Your filter cartridge could be partly blocked with debris: connect the blue
flexible pipe from the filter inlet directly to the boiler (bypass the filter) to
confirm, if needed replace the filter.
Your boiler inlet could be partly blocked with debris: with the water isolated
remove the blue inlet wingnut (G) and inspect the meshed inlet seal (H)
underneath, clean if required.
The aerator on the tap end could be partly blocked with debris or calcified:
follow the aerator descale procedure in this manual.
The data wire (R & X4) connecting
the tap to the boiler is disconnected.
The data wire connecting the tap to
the boiler is damaged.
The boiler is not switched on.
Follow the wire from the tap to boiler.
Check the plugs are firmly connected.
The wire to or from the boiler needs
replacing. Contact the service agent for
parts.
Check the boiler has power and the
display is not showing any error
messages.
