Fixing Malfunctions; Normal Noise While The Appliance Is Working - NEFF T4.D.0 Serie Instrucciones De Uso

Fixing malfunctions

Malfunctions are generally caused by minor faults. Before
contacting the Technical Assistance Service, make sure you
have read the following recommendations and warnings.
Indicator Malfunction

rupted.

nected following the connection diagram.

Do not place hot pans on the control panel.

Normal noise while the appliance is working

Induction heating technology is based on the creation of
electromagnetic fields that generate heat directly at the base of
the pan. Depending on how the pan has been manufactured,
these may produce certain noises or vibrations such as those
described below:
A deep humming sound as in a transformer
This noise is produced when cooking on a high power level.
It is caused by the amount of energy transferred from the hob
to the pan. The noise disappears or becomes faint when the
power level is lowered.
A low whistling sound
This noise is produced when the pan is empty. It disappears
when water or food is added to the pan.
A crackling sound
This noise occurs in pans which are made from different
materials superimposed on one another. It is caused by the
vibrations that occur ajoining surfaces of the different
superimposed materials. The noise comes from the pan.
The amount of food and cooking method can vary.
Measure
Use other electrical appliances to check if there has been a power
cut.
Make sure that the appliance has been connected correctly.
If in the above checks, the malfunction is not resolved, contact the
Technical Assistance Service.
Dry the control panel area or remove the object.
Disconnect the hob from the mains. Wait 30 seconds or so, then con-
nect it again.*
Disconnect the hob from the mains. Wait 30 seconds or so, then con-
nect it again.*
Wait until the electronic system has cooled down completely. Then
press any symbol on the hob.*
Please contact the local electricity board.
Wait until the electronic system has cooled down sufficiently before
switching it back on.
A high-pitched whistling sound
This noise is produced mainly in pans made from different
materials superimposed on one another, and it occurs when
such pans are heated at maximum power on two hotplates at
the same time. The whistling disappears or becomes fainter as
soon as the power level is lowered.
Noise from the fan
For proper use of the electronic system, the temperature of the
hob must be controlled. For this purpose, the hob has a fan
that starts working after detecting excess temperatures at
different power levels. The fan may also work due to inertia
after the hob has been switched off, if the temperature detected
is still too high.
The noises described are normal, they are part of induction
heating technology and not a sign of malfunction.
