9.0 SERVICE
9.1 When the green service indicator light on the front of the unit is
showing solid colour, the machine has been starved of water for in
excess of 20 minutes and the solenoid valve has been disabled to
prevent damage to the solenoid coil through overheat. To re-energise
the solenoid, the unit must be disconnected from the electrical supply
and then switched back on, after first reinstating the water supply.
9.2 If the unit requires servicing the service indicator will flash a sequence
of light pulses. A 2 times or 3 times light pulse generally indicates
that the low or normal level sensors require de-scaling.
9.3 A 4 times 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 remove the flexible hose to check for debris in
the solenoid valve's filter. The unit can be used normally while the
service indicator is flashing a 4 times pulse. For further assistance,
contact the Heatrae Sadia Service Department, telephone 0844 871
1535, fax 0844 871 1528.
9.4 To gain access to internal components, the lid must be removed.
The lid 'pops' off in an upward motion. Beneath the lid there are four
screws holding the steam trap in place. Removing these will allow the
steam trap to be removed and access to the tank will be gained.
To gain access to the rear components the rear panel must be
removed which is held in place by six screws.
NOTE: Whenever the body lid has been removed from the unit a new
lid gasket may be required to ensure a steam-tight joint. Damage to
the unit caused by a poor lid seal is not covered by warranty.
