Trouble Shooting
SELF HELP: If the SB² is not working satisfactorily, make the following checks before calling out the
contractor. Any one of these adjustments could restore the performance.
a) TEMPERATURE READY
light is not on
This is normal: The water has not yet reached the set temperature.
(See Table 3 on page 11 for approximate heat up times).
b) TEMPERATURE READY
light is on but the FULL
light is off
This is normal: Some water has been taken out of the tank so it is
no longer full, but the water temperature is still hot enough to use.
(The tank will automatically fill up again).
c) The FULL light is on but
the TEMPERATURE
READY light is off
This is normal: The tank will have automatically filled and the
heater is still getting the water up to the boil.
(See Table 3 on page 11 for approximate heat up times).
d) The POWER light is on
but the
TEMPERATURE
READY and FULL
lights are both off
This is normal: The tank is still filling up with water and the heater is
still getting up to the boil.
(See Table 3 on page 11 for approximate heat up times).
e) TEMPERATURE READY
light is on but the water is
not boiling
To avoid energy wastage, the SB² is designed to automatically
reduce the temperature by 10°C if the unit is not used for more
than 60 minutes.
(The SB² will automatically go back to boiling when the water is
used).
f) All the lights are out and
the POWER button does
not work
Ensure that the electricity supply is switched on at the local isolator,
and then press the POWER button.
g) The water flowing from the
outlet is sometimes only a
trickle
The water in the tank has been drained out due to a high demand.
Wait for the FULL and TEMPERATURE READY lights to come on
again.
h) The SB² takes a long time
to reach the selected
temperature
When the SB² is first switched on it can take up to 18 minutes to
reach the Boil setting.
(See Table 3 on page 11 for approximate heat up times).
i) Steam and very hot water
sometimes dribble out of
the vent at the back of the
SB²
Check that a pipe has been fitted to the steam vent.
Contact your installer if missing.
Use the POWER button to power down the unit and not the mains
electrical local isolator.
(This will reduce the amount of steam produced).
j) The water tastes different
The new SB² needs to be flushed out before being used first used.
We recommend that the initial tank of boiling water is fully drawn off
and discarded.
Wait for the FULL and TEMPERATURE READY lights to come on,
before using the unit.
k) Solid particles are visible
in the water
Scale has built up inside the tank.
As with all water heaters scale may build up inside the water tank.
How quickly this build up occurs will depend on the hardness of the
water and the usage of the SB².
Descale the SB² heater tank (This should be carried out by a
suitably qualified person).
We recommend the use of inline resin filters to protect the heater.
