Checking Pot Detection - Siemens EH675TK11E Repair Instruction

5.9

Checking pot detection

All inductor areas are fitted with an automatic pot detection system
included in the inductor control system. The minimum diameter is
approximately 50% of the nominal diameter, although this may vary
depending on the material.
When the pot is considered to be of a small size, the inductor control
system automatically reduces the supplied power to adapt to the size
of the pot.
After activating the cook area, if no pot is placed on it or the pot is
made of an unsuitable material, the display showing the level of power
will flash. After 90 seconds the TouchControl will emit an acoustic
warning and turn off the cook area.
When a pot is recognised as suitable, the power level display will
remain constant and the level of power indicated by the display will be
supplied.
5.9.1 Problem
 One inductor plate does not detect a pot but another of a
smaller diameter does.
 The pot is not detected on any inductor plates.
5.9.2 Cause
 The diameter of the pot is not suitable for that hotplate. See
table of recommended minimum diameters.
 The pot is not suitable for our induction technology (the magnet
sticks sometimes). Depending on the composition of the pot,
our technology may not be programmed to detect it as suitable
so as to avoid possible module faults arising from operation in
unsuitable conditions. See power supply reduction or cut-off
diagram depending on the pot being used.

understanding of the problems that may arise in the market.
