Water dripping from the spout end when the handle is in the off position:
Issue description:
Possible issue & solutions:
Water is dripping (continuously from the
centre channel of the spout end aerator).
The hot water on/off valve is leaking, to confirm the fault:
1)
Turn the boiler into standby mode, press and hold the
⏻
key for 1.5 seconds to activate.
2)
Turn the 98°C tap handle off fully.
3)
If the water continues to continuously drip or leak the
boiling water valve needs to be replaced.
Water is dripping (continuously from the outer
channel of the spout end aerator).
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.
Water is dripping (intermittently from the
centre channel of the spout end aerator).
Most typically whilst the boiler is reheating
The expansion chamber in the boiler may be full:
1)
Turn the boiler target temperature to 75°
2)
Turn the 98°C tap handle on fully, run for at least 2 litres
continuously to self-empty the expansion chamber.
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.
Water is dripping (intermittently from the
centre or outer channel of the spout end
aerator typically shortly after each use).
This is water retained within the spout falling due to gravity and is
normal for any tap.
1.3.4
Water flow rate / stream quality:
Issue description:
Possible issue & solutions:
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.
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.
98°C water does not stop the instant the 98°C
handle is turned off.
It is normal for a short delay after the handle is turned off for
water to stop flow as the pressure remaining in the filter and boiler
tank equalise.
