MODEL ...622:
An energy coupling occurs
in the different induction
areas.
It is not a defect; try changing
the power levels chosen.
Sounds similar to "whistles" are heard when two or more induction
areas are activated at high power levels.
When connecting the hob to the power for the first time or after a power fai-
lure, the H of residual heat will turn on in the radiant plates, even though the
glass is cold.
A power failure occurs when
the H were on.
It is not a defect. The H indica-
tors will disappear after some
time has passed.
An L will appear in the indicators and the control will not
work (except models …604)
The control is blocked.
Follow the instructions
manual to unblock the
control.
