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.
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 50%, stir/rearrange 
halfway through reheating.
NOTE:  Ensure the food is thoroughly reheated before 
serving.
Cover with vented microwave cling film and reheat on 
50%. 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 70%.
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 50%.
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.
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 100%, while a lasagne which contains 
ingredients that cannot be stirred, should be reheated using 50%.
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 fi re, 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 fi re.
•  Canned potatoes should not be heated in the microwave oven, follow the manufacturer’s instructions 
on the can.

      WARNING:
Before cleaning, make sure the oven cavity, door, oven cabinet and accessories are 
completely cool.
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. Do not use caustic cleaners 
(including alkali, acid, thinner, benzin, alcohol or 
oven cleaner).
•  Heat up your oven regularly by using the grill, 
refer to "Heating without food" on page 11. 
Remaining food or fat splashed can cause smoke 
or bad smell.
•  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 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 accessories are dishwasher safe.
•  Keep the waveguide cover and accessories clean 
at all times. If you leave grease or fat in the cavity 
or accessories, it may overheat, cause arcing, 
smoke or even catch fire when next using the 
oven.

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.
Door
•  To remove all trace of dirt, regularly clean both 
sides of the door, the door seals and adjacent 
parts with a soft, damp cloth.
•  Do not use harsh abrasive cleaners or sharp 
metal scrapers to clean the oven door glass 
since they can scratch the surface, which may 
result in shattering of the glass.
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.
•  Slight tarnishing of the oven cavity, around the area of the grill, is likely to occur.  This is normal and 
will not affect the ovens performance.
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.

     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.
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 100% 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?
Take the cup of water out of the oven and close 
the door. Programme the oven to cook for 3 
minutes using the grill.
6.  After 3 minutes, does the grill heating 
element become red?
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.
NOTES:
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 element will turn on 
and off.
•  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.

TROUBLESHOOTING
TROUBLESHOOTING CHART
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 from the potatoes and that they 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.
