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 opposite).
•  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.
CLEANING & MAINTENANCE
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.
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.

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. Select HIGH and programme the oven to 
cook for 1 minute.
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 chart below.
NOTE:
If you cook food for more than the standard time 
(see chart below) 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.
IMPORTANT:
If the display is blank and has gone dark, even if
the power plug is properly connected, the oven
may be in Energy Save Mode. To cancel it, open
and then close the oven door, see page 7.
TROUBLESHOOTING
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.

QUERY
ANSWER
Draught circulates around 
the door.
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.
Condensation forms in 
the oven, and may drip 
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.
Flashing or arcing from 
within the cavity when 
cooking.
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.
Arcing potatoes.
Ensure all “eyes” are removed and the potatoes have been pierced, place 
directly onto the turntable or in a heat resistant flan dish or similar.
The display is lit but the 
control panel will not 
work when pressed.
Check the door is closed properly.
Oven cooks too slowly.
Ensure correct power level has been selected.
Oven makes a noise.
The microwave energy pulses ON and OFF during cooking/defrosting.
Outer cabinet is hot.
The cabinet may become warm to the touch - keep children away.

The wires in the mains cable are colour coded as 
shown:
Green and yellow stripes 
EARTH
Blue = 
NEUTRAL
Brown = 
LIVE
As the colours in the mains lead of your oven 
may not correspond with the coloured marking 
identifying the terminals in your plug, connect the 
wires as described:
•  The green and yellow wire to the plug terminal 
marked E or   
  or coloured green or 
coloured green and yellow.
•  The blue wire to the plug terminal marked N 
or coloured black or coloured blue.
•  The brown wire to the plug terminal marked L 
or coloured red or coloured brown.
Make sure the terminal screws are tight and the 
cable is held securely by the cable grip where it 
enters the plug.
Like most appliances in your home, your oven 
must be connected to a single phase 230-240V, 
50Hz alternating current supply.
If you do not make the proper electrical 
connections you might damage the oven or injure 
yourself. Neither SHARP nor the supplier will be 
liable if this happens.
