Fixing Malfunctions; Normal Noise While The Appliance Is Working - Siemens EH8 SP1 Series Instruction Manual

Fixing malfunctions

Malfunctions are usually due to small details. Before calling the
Technical Assistance Service, you should consider the
following advice and warnings.

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,
certain noises or vibrations may be produced 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 in the adjoining surfaces of the different
superimposed materials. The noise comes from the pan. The
amount of food and cooking method can vary.
Solution
power cut.
Check that the appliance has been connected correctly according to
the connection diagram.
If in the above checks, the malfunction is not resolved, contact the
Technical Assistance Service.
Dry the control panel area or remove the object.
Unplug the hob from the mains. Wait about 30 seconds before plug-
ging it in again.*
Unplug the hob from the mains. Wait about 30 seconds before plug-
ging it in again.*
Wait until the electronic system has cooled down completely. Then
push 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 when it detects excess temperatures at
different power levels. The fan may also work by inertia after the
hob has been switched off, if the temperature detected is still
too high.
Rhythmic sounds similar to the hands of a clock
This noise is only produced when the 3 or more left hotplates
are working and disappears or is reduced when one of the
hotplates is switched off.
The noises described are normal, they are part of induction
heating technology and not a sign of malfunction.
