REHEATING ADVICE
Plated meals
Sliced meat
Poultry portions
Casseroles
Remove any poultry or meat portions, reheat
these separately, see below.
Place smaller items of food to the centre of the plate,
larger and thicker foods to the edge. Cover with vented
microwave cling film and reheat on 50P, stir/rearrange
halfway through reheating.
NOTE: Ensure the food is thoroughly reheated before
serving.
Cover with vented microwave cling film and reheat on
50P. Rearrange at least once to ensure even reheating.
NOTE: Ensure the meat is thoroughly reheated before
serving.
Place thickest parts of the portions to the outside of the
dish, cover with vented microwave cling film and reheat
on 70P.
Turn over halfway through reheating.
NOTE: Ensure the poultry is thoroughly reheated
before serving.
Cover with vented microwave cling film or a suitable lid
and reheat on 50P.
Stir frequently to ensure even reheating.
NOTE: Ensure the food is thoroughly reheated before
serving.
For the reheating of foods, follow the advice and guidelines below to ensure food is thoroughly
reheated before serving.
NOTES:
• Remove food from foil or metal containers before reheating.
• Reheating times will be affected by the shape, depth, quantity and temperature of food together with
the size, shape and material of the container.
• To avoid overheating and fire, special care must be taken when reheating foods with a high sugar or
fat content, e.g. mince pies or Christmas pudding.
• Never heat oil or fat for deep frying as this may lead to overheating and fire.
• Canned potatoes should not be heated in the microwave oven, follow the manufacturer’s
instructions on the can.
To achieve the best results when reheating, select a suitable microwave power level appropriate to the
type of food. e.g. A bowl of vegetables can be reheated using 100P, while a lasagne which contains
ingredients that cannot be stirred, should be reheated using 50P.
Never heat liquids in narrow-necked containers, as this could result in the
contents erupting from the container and may cause burns.
The contents of feeding bottles and baby food jars are to be stirred or shaken
and the temperature is to be checked before consumption to avoid burns.

CLEANING & MAINTENANCE
OVEN INTERIOR
• It is important to clean the interior of your
microwave oven after each use.
• To clean the oven interior, use a mild detergent
solution, such as washing-up liquid, with warm
water on a soft cloth.
• Food and liquid splashes will build-up on the
oven walls and ceiling. If grease, fat and food
debris is allowed to build-up in the oven
interior it may overheat, smoke or even catch
fire when next using the oven.
• Keep the waveguide cover clean at all times.
The waveguide cover is constructed from a
fragile material and should be cleaned with
care (follow the cleaning instructions above).
NOTE: Excessive soaking may cause
disintegration of the waveguide cover.
The waveguide cover is a consumable part and
without regular cleaning, will need to be
replaced.
• Food will release steam during cooking and
cause condensation inside the oven and door.
It is important to wipe the oven dry. A build-
up of condensation will eventually lead to rust
forming on the oven interior.
• Do not allow grease or dirt to build-up
on the door seals or areas around the
door. This may prevent the door from
closing correctly and may cause a
leakage of microwaves (follow the
cleaning instructions).
• Ensure the turntable and roller stay are
cleaned after every use with a mild washing-up
liquid solution and dried. This will prevent the
build-up of grease and food debris.
The turntable is dishwasher safe.
• CLEAN THE OVEN AT REGULAR
INTERVALS AND REMOVE ANY FOOD
DEPOSITS.
Failure to maintain the oven in a clean
condition could lead to a deterioration of
the surface that could adversely affect
the life of the appliance and possibly
result in a hazardous situation.
OUTER CABINET
• Wipe the outside of the microwave oven with
a mild detergent solution, such as washing-up
liquid, with warm water on a soft cloth.
• The control panel must be wiped clean and
dried with the door open, therefore
inactivating the oven.
NOTES:
• Never use spray cleaners, oven pads or abrasive scourers as these damage the surface of the oven.
• A steam cleaner should not be used.
• Take care not to let soapy water drip through the small holes in the oven walls and the cavity floor.
Excess water spillage through these holes will cause damage to the oven interior.
Cleaning tip - For easier cleaning of your oven:
Place half a lemon in a bowl, add 300ml (1/2 pint) water and heat on 100P for 10 - 12 minutes.
Wipe the oven clean using a soft, dry cloth.

TROUBLESHOOTING
If you think the oven is not working properly there are
some simple checks you can carry out yourself before
calling an engineer. This will help prevent unnecessary
service calls if the fault is something simple.
Follow this simple check below:
Place half a cup of water on the turntable and close the
door. Programme the oven to cook for 1 minute using
100P microwave power.
1. Does the oven lamp come on when it is cooking?
2. Does the turntable rotate?
3. Does the cooling fan work? (Check by placing your
hand above the air vent openings.)
4. After 1 minute does the audible signal sound?
5. Is the water in the cup hot?
If you answer “NO” to any question first check that the
oven is plugged in properly and the fuse has not blown.
If there is no fault with either, check against the
troubleshooting chart below.
NOTE: If you cook food for more than the standard time
(see chart opposite) using the same cooking mode,
the oven’s safety mechanisms automatically activate.
The microwave power level will be reduced.
• The door seal stops microwave leakage during oven
operation, but does not form an airtight seal. It is
normal to see drops of water, light or feel warm air
around the oven door. Food with a high moisture
content will release steam and cause condensation
inside the door which may drip from the oven.
• Repairs and Modifications: Do not attempt to
operate the oven if it is not working properly.
• Outer Cabinet & Lamp Access: Never remove the
outer cabinet. This is very dangerous due to high
voltage parts inside which must never be touched, as
this could be fatal.
Your oven is not fitted with a lamp access cover. If
the lamp fails, do not attempt to replace the lamp
yourself, call a SHARP approved service facility.
WARNING:
Never adjust, repair or modify the oven
yourself. It is hazardous for anyone other than
a SHARP trained engineer to carry out
servicing or repairs.
This is important as it may involve the
removal of covers that provide protection
against microwave energy.

ANSWER
When the oven is working, air circulates within the cavity.
The door does not form an airtight seal so air may escape from the door.
The oven cavity will normally be colder than the food being cooked, and so steam
produced when cooking will condense on the colder surface.
The amount of steam produced depends on the water content of the food being
cooked. Some foods, such as potatoes have a high moisture content.
Condensation trapped in the door glass should clear after a few hours.
Arcing will occur when a metallic object comes into close proximity to the oven
cavity during cooking. This may possibly roughen the surface of the cavity, but
would not otherwise damage the oven. 
Ensure all “eyes” are removed from the potatoes and that they have been
pierced, place directly onto the turntable or in a heat resistant flan dish or
similar.
Check the door is closed properly.
Ensure correct power level has been selected.
The microwave energy pulses ON and OFF during cooking/defrosting.
The cabinet may become warm to the touch - keep children away.
QUERY
Draught circulates around the
door.
Condensation forms in the
oven, and may drip from the
door.
Flashing or arcing from within
the cavity when cooking.
Arcing potatoes.
The display is lit but the control
panel will not work when pressed.
Oven cooks too slowly.
Oven makes a noise.
Outer cabinet is hot.
