Trouble shooting
SELF HELP (See Table 1) – If the SB 2 is unsatisfactory, then make the following checks before
calling out the contractor. Any one of these adjustments could restore the performance.
Table 1
a) TEMPERATURE READY
light is not on
This is normal: The water has not reached the set temperature.
(See Table 3 on page 10 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).
c) The FULL light is on but
the TEMPERATURE
READY light is off
This is normal: The tank has automatically filled itself
and the heater is still getting the water up to the boil.
(See Table 3 on page 10 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 itself with water and the
heater is still getting up to the boil. (See table 3 on page 10 for
approximate heat up times).
e) TEMPERATURE READY
light is on but the water is
not boiling
To avoid energy wastage, the SB 2 is designed to automatically
reduce the temperature by 10ºC if the unit is not used for
more than 60 minutes. (The SB
2 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
isolator, 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 & TEMPERATURE READY lights to
come on again.
h) The SB 2 takes a long time
to reach the selected
temperature
When the SB 2 is first switched on it can take up to 18 minutes
to reach the Boil setting. (See Table 3 on page 10 for
approximate heat up times).
i) Steam and very hot water
sometimes dribbles out of
the vent hole at the back of
the
SB 2
Check that a pipe has been fitted to the steam vent. Contact
your installer if this is missing.
Use the POWER button to power down the unit and not the
main electrical isolator. (This will reduce the amount of steam
produced).
j) The water tastes different A new SB 2 needs to be flushed out before being first used.
We recommend that the initial tank of boiling water is fully
drawn off and discarded. Wait for the FULL & 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 will 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 SB
2 .
Descale the SB 2 heater tank. (This should be carried out by a
qualified electrician).
We recommend the use of in line resin filters to protect the
heater.
