ALL THESE THINGS ARE NORMAL:
Sounds will occur when 
using the Steam function.
This is caused by air mixed when the water tank is working. It is 
normal.
The sound of “Bar... Bar...” 
may be emitted at the back 
of the oven cavity during 
and after the use of different 
kinds of Convection function.
This is a cause of thermal expansion and contraction of the metal 
material used in the product. It is normal.
Steam accumulates on 
the oven door and warm 
air comes from the air 
outlet.
During cooking, steam and warm air are given off from the food. 
Most of the steam and warm air are removed from the air outlet by 
the air which circulates in the oven cavity. However, some steam will 
condense on cooler surfaces such as inside or on the oven door. 
 
It is normal.
Steam leaks out from all 
four sides of the oven 
door.
When a function related to steam is used, a lot of steam are 
generated in the oven cavity during operation of the product. Some 
steam may leak from all four sides of the oven door. It is normal.
I accidentally operated 
my oven without any food 
in it.
Operating the oven empty for a short time will not damage the oven, 
however, it is not recommended.
The oven has an odour 
and generates smoke 
when using Convection 
and Steam Convection 
function.
It is essential that your oven is wiped out regularly, particularly after 
cooking by Convection and Steam Convection. Any fat and grease 
that builds up on the roof and walls of the oven will begin to smoke 
if not cleaned.
The fan motor continues 
operating after cooking is 
over.
After using the oven, the fan motor will operate for several minutes 
to cool the oven and electric components. It is normal.
The rear side of the oven’s 
color has yellowing.
Metal ions will generate yellow marks when heated. It is normal that 
will not affect the use of the oven and harm to human health.
Door seal maybe 
deformed.
The door seal may be distorted due to high temperature. It is 
normal and will not affect the performance of use of the oven.
Some smoke and odour 
will be given off from the 
cavity when using different 
kinds of Convection 
functions for the first time.
It is caused by the excessive oil in the cavity used for rust 
protection.
The part where the power 
supply cord connects to 
the product’s bottom plate
has loosened.
It is normal.
