Repair instructions
•
Never attempt to carry out repairs by “randomly replacing” components!
•
Always proceed systematically and observe the technical documentation that goes with the
appliance!
•
Electronic circuit boards are generally not repaired; instead they are completely replaced with original
spare parts. Exceptions are documented separately.

General information on induction
The inductive component is a choking coil which directly converts magnetic energy into heat.
Induction is based on the principle of the electromagnetic field.
The principle of heating by induction is a natural phenomenon discovered in the 19th century by several
physicists, among whom Léon Foucault. He highlighted the development of currents facing the magnetic
field in a moving metallic mass or a fixed metallic mass run through by a variable magnetic flux. These
eddy currents in comparison to short-circuits cause a heating effect (Joule effect) in the mass.
Since the middle of the 20th century induction started being used as a heating means. Induction only
found its place in kitchens in the 80s, or even 90s for domestic electrical appliances.
The operating principle is innovating. Contrary to other cooking modes, it is the container itself, which
heats and not the hob.
You put a saucepan down and this is sufficient to initiate the heat while the hob remains cold. The heating
element is nothing but the container metal, which transforms the magnetic energy into thermal energy.
Induction qualities are flexibility, low inertia, easy cleaning, good efficiency and thermal safety.
Induction enables a litre of water to boil in two minutes, milk to heat without overflowing and chocolate
to melt just as desired. Induction efficiency may reach up to 90% according to the types of cooking.
With such a technique, only the container heats. Inertia is therefore low and, above all, the plate
temperature never exceeds the saucepan temperature.
Stepping from the mildest temperature to the strongest power, in an instant and while diffusing heat in a
homogeneous way, attracts more and more consumers.

Introduction
The aim of the present document note is introducing the new G1 range of induction hobs, showing the
main features, its configuration mode and the error messages that could appear during the normal use
of the end customer.
Besides it, it is given a brief explanation about how to substitute some of the most important components
during the reparation procedures.
