Power source
Check the following information before making inquiries or requesting service.
Operation panel
Sounds and noises
Heat power
Symptom Probable cause
The IH cooktop cannot
be turned ON.
- The main power switch has not been turned ON.
The power switch was designed so that it will not be easily
turned on if it is mistakenly touched.
Touch the main power switch a little longer.
- The “Child safety lock” has been activated.
Main power switch auto shutoff
If 1 minute has elapsed without any operation since the main
power switch was turned on, the main power automatically
turns off.
Turn on the main power switch again.
The “Deep frying temperature control sensor” and the left
rear IH heater cannot be used simultaneously.
The IH heater turned
itself off while being
used.
Forgotten-OFF auto shutoff
If no key is touched for approx. 45 minutes while an IH
heater is in operation, a buzzer will sound and the IH heater
is automatically turned off.
Touch the key again.
* The timer is recommended for simmering.
Symptom Probable cause
Key operation is
disabled.
- Your fingertips are covered or have bandages on them.
- You performed the operation while holding the cookware
handle.
- The operation panel is stained.
Turn off the main power switch and remove any foreign
objects. Then, turn on the main power switch again.
* Remove after cooking when deep-frying.
Keys react even when
only their vicinity is
touched.
Water is on or around the keys, for example.
Symptom Probable cause
Noise is heard during
heating.
Various resonant sounds may be heard depending on the
type of cookware. You may feel a small vibration when you
hold the handle and the cookware may slightly move.
This is not a malfunction. Moving the cookware slightly or
replacing it may be able to get rid of the sound.
If the cookware is removed while being heated, a short
metallic sound may be heard.
The level of the
noise from the main
unit increases and
decreases.
It is the noise from the cooling fan inside the main unit. The
level of the noise changes according to the heat level and
the material the cookware is made of.
(When the heat level is increased, the fan will operate at high
speed and generate more noise.)
Even after the main
power switch is turned
off, noise from the fan is
still heard.
While the inside of the main unit is still hot, the cooling fan
operates.
(When the temperature decreases, it will automatically stop.)
Symptom Probable cause
The heating power of
the IH heater seems to
be weaker.
Overheating prevention function
If the bottom of the cookware overheats, for example, when
preheating too long, the heating power will automatically
decrease without the power indication changing.
(The function ends after the appliance cools down.)
Cookware, such as ceramic and earthenware pots, which
cause the IH heater to overheat are used.
Do not use ceramic and earthenware pots even if they are
for induction heating.
When several IH
heaters are used
simultaneously,
- The heating power
decreases.
- The power indicator
automatically
decreases.
- The heat level does
not increase.
The heat level is automatically controlled so that overall
power consumption does not exceed the limit. (See page
25.)
* The power indicator for an IH heater may decrease on its
own. Even after touching , it may not increase and the
appliance may beep.
