Interference with and repairs to the hob MUST NOT
be carried out by unqualified persons. Do not try
to repair the hob as this may result in injury and
damage to the hob. Please arrange for repair by a
suitably competent person.
Note: The induction hob is able to self-diagnose a
number of problems and can show this information to
the user via the hob control display. Error codes may be
displayed if your hob has developed a fault.
If your appliance reports an error or is not working,
you may be able to correct the fault by consulting the
following.
Error code E2 is displayed
The electronic unit is too hot. Please check the
installation of the cooker, making sure that there is
sufficient ventilation. In extreme cases, if a cooking
utensil has been allowed to boil dry this error code
may also be displayed. If in doubt please contact your
installer or a qualified repair engineer.
No display operation
Over voltage or loss of supply voltage to the cooker. If in
doubt please contact your installer or a qualified repair
engineer.
Error code U400 is displayed
The cooker has been incorrectly connected. The control
will switch off after approximately 1 second and the
error code will be permanently displayed.
Consult your installer or a qualified repair engineer.
Error code Er followed by a number is displayed
The appliance has developed an internal technical fault
that cannot be rectified by the user.
Consult your installer or a qualified repair engineer.
The fuse blows or the RCD trips regularly
Please contact your installer or a qualified repair
engineer.
The hob will not switch on
Has the wiring system in the house blown a fuse or
tripped an RCD?
Has the hob been correctly connected to the mains
supply?
Has the child lock been activated? Please refer to the
child lock section for details of this function.
The induction hob is noisy
When using the induction hob there may be some
‘noise’ emitted from the pan. This is normal and may be
most noticeable when cooking on high power settings
or if 5 pans are used simultaneously. The type of pan
may also contribute to induction ‘noise’.
The cooling fan
The induction hob incorporates a cooling fan. This
cooling fan is active when either the grill or ovens
are on. Under certain conditions, the cooling fan may
remain active when the grill or ovens are switched off.
This is normal and the fan will switch off automatically.
A crack has appeared in the hob surface
Disconnect the cooker immediately from the power
supply and arrange for its repair. Do not use the cooker
until after the repair.
My hob is scratched
Always use the cleaning methods recommended in this
guide, and make sure that the pan bottoms are smooth
and clean.
Marks from mineral deposits from water or food can be
removed with a cleaning cream. However, tiny scratches
are not removable but will become less visible in time as
a result of cleaning.
The oven fan is noisy
The sound of the oven fan may change as the oven
heats up – this is perfectly normal.
Grill not cooking properly
Are you using the pan and trivet supplied with the
cooker? Is the grill tray pushed back fully to the ‘back
stop’ position?
The knobs get hot when I use the oven
or grill. Can I avoid
this?
Yes, this is caused by heat rising from the oven or the
grill, and heating them up. Do not leave the oven door
open. Make sure that the grill pan is pushed right back
to the ‘back stop’ when grilling.
If there is an installation problem and I don’t get my
original installer to come back to fix it, who pays?
You do. Service organisations will charge for their call-
outs if they are correcting work carried out by your
original installer. Therefore, it’s in your own interest to
keep track of this installer so that you can contact them
as required.
Food is cooking too slowly, too quickly, or burning
Cooking times may differ from your previous oven.
Check that you are using the recommended
temperatures and shelf positions – see the oven
cooking guide.
You can then adjust the settings according to your own
individual tastes.
The oven is not cooking evenly
Do not use a baking tray with dimensions larger than
those specified in the section on ‘General Oven Tips’.
