The boiling water flow is agitated and noisy
Please bear in mind that your Franke Omni system is
dispensing boiling water, rather than very hot water, and as a
consequence there will be the normal steam, agitation and
noise associated with boiling water. Initially this may be
alarming, but read through the technique suggested below
and practice it a few times. Soon you will gain confidence and
using the tap will be second nature.
Operate the boiling water function. Discharge a small amount
of water until steam appears. Turn off the boiling water,
position the vessel over the outlet of the tap spout and
continue to dispense boiling water by maintaining pressure
on the handle. Gradually lower the vessel while keeping the
spout just above the surface of the water.
Please take a moment to visit www.franke.co.uk for a short
video demonstration of an Omni in use to accompany the
above instructions.
The flow of boiling water splutters more than shown
in the video
• Check that the stop valve is fully open and for kinks in the
flexible hoses; particularly the boiling water hose.
• If this does not resolve the issue, check the water
pressure using a gauge rather than estimating to ensue a
reliable reading. As previously stated it should fall
between 1.5 bar (22 psi) 5 bar (73psi).
• If the problem persists, remove the filter cartridge and try
running the system without the cartridge installed to
determine whether the cartridge is blocked and restricting
the flow.
Water fails to discharge from the vent tube after power
has been switched on to the boiler for 10 minutes
• Check there is power to the boiler. The ‘Plug’ LED should
be green. Check there are no kinks in the vent hose.
Water is continually dripping/running into the
vent assembly
Water continuously discharging from the vent indicates that
the water pressure is too high; above the 5 bar (73 psi)
stipulated maximum. In normal operation the pressure relief
valve will allow water to drip for approximately 20 minutes
after the boiler is switched on. Thereafter it will drip
periodically; after water is drawn off and as the boiler comes
back up to temperature.
Check the water pressure at a low demand period (mid
morning or mid afternoon). If it exceeds 5 bar (73 psi)
it will be necessary to install a 3-4 bar pressure reducing valve.
A suitable valve can be purchased at
www.frankefilterflow.co.uk or from a plumber’s merchant.
While waiting for the pressure relief valve to be fitted turn
off the boiler.
