The vent assembly is overflowing
• Check that the has been hole has been properly cut in the
waste pipe.
The hot water flow from the tap is slow (not the
boiling water)
• Check the hot water pressure. A minimum of 0.8 bar
pressure is required.
The filtered cold and boiling water flow from the
tap is slow
• Generally this indicates that the filter cartridge is clogged
with contaminants and needs replacing. You can check by
operating the filtered water with no cartridge in the filter
housing.
The flow of filtered water has slowed to an unacceptable
level inside the 6 months change period
• The period between cartridge replacements is not
guaranteed; it is an estimate based on filtering mains
water of average quality. Please bear in mind that water
quality varies from locality to locality and situation to
situation. In areas with higher than average turbidity
(particle contamination) more frequent cartridge changes
may be necessary.
The boiling water function is dispensing cold water
instead of boiling water
• Check that the electrical supply is correctly connected.
• Check the 13amp fuse in the plug.
• If you are still experiencing problems after completing
these steps please contact Franke FilterFlow on 01603

Unsightly deposits on the surface of a cup of tea
• In hard water areas a ‘scum’ can appear on the surface of
hot tea. Although unsightly it is completely harmless. The
cause is related to the precipitation of calcium and
magnesium in hard water regions and a reaction with the
tea bag material. Changing tea bags will often remedy the
problem. Alternatively you can consider switching to a
Franke 06 cartridge which will remove the calcium and
magnesium however please note this filter will need to be
change more frequently, perhaps every 2- 3 months. The
life of the Franke 06 is dependent on the hardness of the
water supply and the volume of water passed through it, so
is impossible possible to predict, however the return of the
‘scum’ on hot drinks is an indication it should be replaced.
Foam is forming on the surface of hot drinks
• This is caused by a combination of the agitation of the
boiling water creating millions of tiny air bubbles and the
amount of oil in the teabag material. To reduce the problem
try filling the teapot or cup with boiling water and allowing
the water to settle before dropping the tea bag in rather
than running the boiling water directly onto the teabag, or
perhaps experiment with different brands of tea bag.
Milky or cloudy appearance of the filtered water
• A new filter cartridge has a significant amount of air
trapped in the microporous structure of the cartridge.
This will form tiny bubbles and give the water in the glass
a milky appearance that will soon disperse when left to
stand for a few moments. This may continue for 2 to 3
weeks until the cartridge is fully conditioned.
Tiny black specks in the water
• Tiny black specks may appear initially in the water. These
are harmless particles of carbon; residues from the
manufacturing process. Allow the filtered water to
continue flowing for a while until they are completely
flushed through.
Condensation is dripping from exposed copper pipes
adjacent to the boiler
• This can be reduced by wrapping insulation around the
pipes in question.
