OVEN INTERIOR
Clean the microwave oven cavity after each
use with a mild detergent  solution on a soft
cloth, pay special attention to the waveguide
cover. Built up splashes may overheat and
begin to smoke or catch fire, and cause
arcing.
After Grill, Convection, Dual, AutoCook and Express
Cook modes the oven cavity, door, cabinet and
accessories will become very hot. Before cleaning,
ensure that they have cooled down.
Ensure all food splashes are wiped off immediately
after use, otherwise it is possible that any food
deposits will become baked onto the rear of the oven
cavity resulting in staining of the polished surface,
which may then be impossible to remove. Slight
tarnishing of the oven cavity around the area of the
convection and grill heaters is likely to occur. This
effect does not indicate a problem.
Take care not to let soapy water drip through the small
holes in the oven walls and the cavity floor particularly
if the turntable and turntable support are removed.
Excess water spillage through these holes will cause
damage to the oven interior. Heat up your oven
regularly by using the convection and grill without
food, refer to the notes on pages 10 and 11.
• Do not allow grease or dirt to build up on
the door seals and adjacent parts as this
may prevent the door from closing
correctly and may cause a leakage of
microwaves. To clean use a mild
detergent  solution on a soft damp cloth.
• Keep the waveguide cover and
accessories clean at all times. If you leave
grease or fat in the cavity, it may
overheat, cause arcing, smoke or even
catch fire when next using the oven.
• Never use spray cleaners, oven pads or
abrasive scourers as these damage the
surface of the oven.
Remaining food or fat splashed on the oven interior
can cause smoke or a bad smell. To prevent
splashing, cover food whenever possible.
