Trouble Shooting
SELF HELP: If the SB² is not working satisfactorily, make the following checks before callingout the
contractor. Any one of theseadjustmentscould restore the performance.
a) TEMPERATURE READY
light isnot on Thisisnormal: The water hasnot yet reachedthe set temperature. (See Table3 on page 10 for approximate heat up times).
b) TEMPERATURE READY
light isonbut the FULL
light isoff
Thisisnormal: Some water hasbeen takenout of the tankso it is
no longer full, but the water temperature is still hot enough to use.
(The tankwill automatically fill upagain).
c) The FULL light ison but
the TEMPERATURE
READY light isoff
Thisisnormal: The tankwill have automaticallyfilled and the
heater is still getting the water upto theboil.
(See Table3 on page 10 for approximateheat up times).
d) The POWER light is on
but the
TEMPERATURE
READY and FULL
lightsare both off
Thisisnormal: The tankisstill filling up withwater and the heater is
stillgetting up tothe boil.
(See Table3 on page 10 for approximateheat up times).
e) TEMPERATURE READY
light isonbut the water is
not boiling
To avoidenergy wastage, the SB² isdesigned to automatically
reduce the temperature by10°C if the unit isnot usedfor more
than 60 minutes.
(The SB² will automatically go back to boiling when the water is
used).
f) All thelightsareout and
the POWER buttondoes
not work
Ensure that the electricitysupply isswitched on at the local isolator,
andthen press the POWER button.
g) The water flowing from the
outlet is sometimesonly a
trickle
The water in the tankhasbeen drained out due toa high demand.
Wait for the FULLandTEMPERATURE READY lights to comeon
again.
h) The SB² takesa long time
toreachtheselected
temperature
When the SB² is first switched on it can take up to18minutes to
reach the Boil setting.
(See Table3 on page 10 for approximateheat up times).
i) Steam and very hot water
sometimesdribble out of
the vent at the back of the
SB²
Check that a pipehasbeen fittedto thesteam ve
nt.
Contact your installer if missing.
Use the POWER button topower down the unit and not the mains
electrical local isolator.
(This will reducetheamount of steam produced).
j) Thewater tastes different The new SB² needsto be flushed out before being used first used.
Werecommendthat the initialtankof boiling water isfully drawn off
anddiscarded.
Wait for the FULLandTEMPERATURE READY lights to comeon,
before using theunit.
k) Solid particles are visible
in the water Scale has built up inside thetank.
As with all water heatersscale may build up inside the water tank.
How quickly this build up occurs willdepend on the hardness of the
water and the usageof theSB².
Descalethe SB² heater tank(Thisshouldbecarried out by a
suitably qualifiedperson).
Werecommendthe useof inline resin filtersto protect the heater.
