CARE AND CLEANING
C AUTION: DO NOT USE COMMERCIAL OVEN

HARSH CLEANERS, ANY THAT CONTAIN SODIUM 
HYDROXIDE OR SCOURING PADS ON ANY PART OF 
YOUR MICROWAVE OVEN.
CLEAN THE OVEN AT REGULAR INTERVALS AND 
REMOVE ANY FOOD DEPOSITS - Keep the oven 
clean, or the oven could lead to a deterioration of 
the surface. This could adversely aff ect the life of 
the appliance and possibly result in a hazardous 
situation.
Oven exterior
The outside of your oven can be cleaned easily with 
mild soap and water. Make sure the soap is wiped off  
with a moist cloth, and dry the exterior with a soft 
towel.
Control panel
Open the door before cleaning to de-activate the 
control panel. Care should be taken in cleaning the 
control panel. Use a cloth damp with water only, 
gently wipe the panel until it becomes clean.
Avoid using excessive amounts of water. Do not use 
any sort of chemical or abrasive cleaner.
Oven Interior
1. For cleaning, wipe any splatters or spills with a soft 
damp cloth or sponge after each use while the oven is 
still warm. For heavier spills, use a mild soap and wipe 
several times with a damp cloth until all residues are 
removed. Do not remove the waveguide cover.
2. Make sure that mild soap or water does not 
penetrate the small vents in the walls which may 
cause damage to the oven.
3. Do not use spray cleaners on the oven interior.
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.
Turntable and Turntable support
Remove the turntable and turntable support  from the 
oven.
Wash the turntable and turntable support in mild 
soapy water. Dry with a soft cloth. Both the turntable 
and the turntable support are dishwasher safe.
Door
To remove all traces 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 glass oven door 
since they can scratch the surface, which may result in 
shattering of the glass. 
NOTE: A steam cleaner should not be used.
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.
GB-16
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 protec tion against 
microwave energy.
•  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.
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?
 
If you answer “NO” to any question fi rst 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. 
 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 fl an 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.

TO REPLACE THE MAINS PLUG
IMPORTANT!
•  The fuse from the cut-off  plug should be removed 
and the plug disposed of in a safe manner.
•  Under no circumstances should the cut-off plug 
be inserted into a socket outlet as a serious electric 
shock may occur.
•  The plug must not be used without the fuse cover 
fi tted.
If you have any doubt about your microwave oven 
obtain the help of a qualified electrician. When 
replacing the plug please ensure that you use a BSI or 
ASTA approved plug to BS1363, this should be fi tted 
with a brown coloured 13 amp fuse approved by 
BSI or ASTA to BSI 362. If you have any doubt about 
electrical connection seek the help of a qualified 
electrician.
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.
WARNING: THIS APPLIANCE MUST BE EARTHED
If you have any doubts about your electrical 
supply ask a qualifi ed electrician.
