CLEANING & MAINTENANCE
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 grills, 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:
Before cleaning, make sure the oven cavity, door, oven cabinet, accessories and especially 
the grills are completely cool.
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.
•  Heat up your oven regularly by using the
   grills, refer to NOTE on page 12. 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 buildup 
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 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.
•  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.

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 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 convection 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.
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 
elements will turn on and off.
•  After manual or automatic cooking using the 
Grill, Dual Cook or Convection 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.
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 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.
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
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.
Your oven may be set in Demo Mode. To cancel Demo Mode, unplug the 
oven from the socket and replug.
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.
The display shows 
message for “DEMO 
MODE”, or the time in 
the display is counting 
down very rapidly.
