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 cooker will not switch on

Has the wiring system in the house blown a fuse or tripped an 

RCD?
Has the cooker been correctly connected to the mains 

supply?

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 the oven(s) are on. Under 

certain conditions, the cooling fan may remain active when 

the grill or oven(s) are switched off. This is normal and the fan 

will switch off automatically.

The fascia gets hot when I use the oven

If the fascia becomes excessively hot when the cooker is in 

use then the cooling fan may have failed. Should this occur 

please contact your installer, a qualified repair engineer or 

Customer Service to arrange for its repair.

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 note of the oven fan may change as the oven heats up – 

this is perfectly normal.

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.

ALWAYS grill with the grill compartment door open.
DO NOT leave the oven door open.

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. Then adjust the 

settings according to your own individual tastes.
