Normal Operating Noises; Causes Of Damage - Thermador PRD364WIGU Guía De Uso Y Cuidado

Normal operating noises

Induction technology is based on the creation of
electromagnetic fields. They may generate heat directly
on the bottom of the cookware. Pots and pans may cause
a variety of noises or vibrations depending on the way
they've been manufactured. These noises are described as
follows:
Low humming (like a transformer)
This noise is produced when cooking at a high heat level.
It is based on the amount of energy transferred from the
cooking surface to the cookware. The noise ceases or
quiets down when the heat level is reduced.
Quiet whistling
This noise is produced when the cooking vessel is empty.
It ceases once water or food is placed in the vessel.
Crackling
This noise occurs with cookware comprised of various
materials layered one upon the other. It is caused by the
vibrations of the surfaces where different materials meet.
The noise occurs on the cookware and can vary
depending on the amount and method of preparation of
the food.
Loud whistling
This noise occurs with cookware comprised of different
materials layered one upon the other, and when they are
additionally used at maximum output and also on two
cooking zones. The noise ceases or quiets down when the
heat level is reduced.
The noises described are a normal element of the
described induction technology and should not be
regarded as defects.

Causes of damage

Saucepan and pan bases
• Rough saucepan bases can scratch the induction
surface. Check your cookware.
• Avoid boiling the pan dry, especially with enamel
pans. This damages both the pan base and the
induction surface.
• Observe the manufacturer's instructions when using
special cookware.
Salt, sugar and sand
• Salt, sugar and sand can scratch the induction surface.
DO NOT use the glass as a work surface or a storage
area.
• Sugar and foods with a high sugar content can
damage the Induction Module. Remove food spills
immediately with a glass scraper.
Hard and pointed objects
• Hard or pointed objects can damage the induction
surface if they fall on the surface. DO NOT store such
objects over the appliance.
DO NOT operate this appliance if it is not working
properly, or if it has been damaged. Contact an authorized
servicer.
DO NOT cook on a broken surface. Cleaning solutions
and spillovers may create a risk of electric shock.
DO NOT repair or replace any part of the appliance unless
specifically recommended in this manual. Refer all
servicing to a factory authorized servicer.
Examples of possible damage
The following types of damage have no effect on either
the function or the integrity of the induction surface top.
Pitting
Pitting is caused by melted sugar or foods
with a high sugar content.
Scratches
Scratches are caused by grains of salt, or
sand, or by the rough bottom of a pan.
Discoloration with a metallic sheen
Discoloration is caused by pan abrasion or
an unsuitable cleaning agent.
Dulled markings
Dulled marking are caused by an
unsuitable cleaning agent.
