When the red ‘Service’ indicator light on the front of the boiler is
illuminated (solidly), the machine has been starved of water in excess
of 30 minutes and the solenoid valve has been disabled to prevent
damage to the solenoid coil through overheat. To re-energise the
solenoid, the electrical supply must be switched off and then on again,
after first reinstating the water supply.
If the unit requires servicing, the red ‘Service’ indicator will flash a
sequence of light pulses. A 2x or 3x light-pulse generally indicates
that the low or normal level probes require de-scaling.
A 4x or 6x light-pulse means the water level has reached the high
level sensor and the likelihood is that the normal level sensor requires
de-scaling, or the machine has over-filled due to debris trapped in
the solenoid valve. The debris can be removed by drawing plenty of
water from the dispense tap, causing the solenoid valve to operate
and flush out the obstruction. The machine will reset itself once the
problem has cleared. If this does not rectify the problem, turn off the
water supply and check for debris in the solenoid valve filter. The
unit can be used normally while the service indicator is flashing a
4x pulse. For further assistance, contact our service department on

Access to internal components can be gained by the removal of the
outer casing lid and front panel. Once the outer casing is removed,
access to the Service Area has been gained. This access must be
restricted to persons having knowledge and practical experience of the
appliance, in particular as far as safety and hygiene are concerned.
