• 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 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
• 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
cleaning instructions opposite).
• Ensure the turntable and accessories 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 and accessories are dishwasher
• 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.
• It is important to keep the grills clean at all
• Food and liquid splashes build-up and stick to
the grill, which may cause smoke and possibly
fire when next using the oven (follow the
cleaning instructions above).
• Never use spray cleaners, oven pads or abrasive scourers as these damage the surface of the oven.
• 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.
• Slight tarnishing of the oven cavity, around the area of the grills, is likely to occur. This is normal and
will not affect the ovens performance.
• Failure to maintain your oven in a clean condition could adversely affect the life of the oven and
possibly result in a hazardous situation.
Cleaning tip - For easier cleaning of your oven:
Place half a lemon in a bowl, add 300ml (1/2 pint) water and heat on 100% for 10 - 12 minutes.
Wipe the oven clean using a soft, dry cloth.
The door, outer cabinet, oven cavity, turntable, dishes, accessories and especially the grills
will become very hot during operation. Before cleaning, ensure they have cooled down.

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 100% microwave power.
1. Does the oven lamp come on when it is
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?
Take the cup of water out of the oven and close
the door. Programme the oven to cook for 3
minutes using the top and bottom grills.
6. After 3 minutes, do both the grill heating
elements become red?
Programme the oven to cook for 3 minutes using
the oven on 180ºC.
7. After 3 minutes, is the oven cavity 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 on the
following page.
• 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 or the grill heating
elements will turn on and off.
• After manual or automatic cooking using the
Grill, Dual Grill or Oven modes, the cooling
fan will switch on to cool the oven cavity.
When the cooling fan works, the display may
show “NOW COOLING”. To clear it, press
the STOP/CLEAR key and the display will
return to the time of day, if set.
During these modes, the cooling fan will carry
on working after you have pressed the
STOP/CLEAR key. You may feel hot air
blowing out of the air-vent openings.
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 8.
• 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.
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.

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 and the potatoes 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.
Draught circulates
around the door.
Condensation forms in
the oven, and may drip
from the door.
Flashing or arcing from
within the cavity when
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.

The wires in the mains cable are colour coded as
Green and yellow stripes
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.
If you have any doubts about your
electrical supply ask a qualified
