CARE AND CLEANING
CAUTION: DO NOT USE COMMERCIAL OVEN CLEANERS, STEAM
CLEANERS, ABRASIVE, HARSH CLEANERS, ANY THAT CONTAIN
SODIUM HYDROXIDE OR SCOURING PADS ON ANY PART OF
YOUR MICROWAVE OVEN.
Before cleaning, make sure the oven cavity, door, oven cabinet
and accessories are completely cool.
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.
Oven controls
Open the door before cleaning to de-activate the oven controls.
Care should be taken when cleaning the oven control. Using a cloth
dampened 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 away 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. Built-up splashes may
overheat and begin to smoke or catch fi re, and cause arcing. Do
not remove the waveguide cover.
2. Make sure that the 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 type cleaners on the oven interior.
4. Heat up your oven regularly by using the convection and grill.
Remaining food or fat splashed can cause smoke or bad smell.
5. 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.
SPECIAL NOTE for WAVEGUIDE COVER: 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 in-
structions above).
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.
Accessories
The accessories like turntable, turntable support, rack and crisp plate
should be washed in a mild washing up liquid solution and dried.
They are dishwasher safe.
SPECIAL NOTE for TURNTABLE SUPPORT:
After cooking, always clean the turntable support, especially around
the rollers. These must be free from food splashes and grease. Built-
up splashes or grease may overheat and cause arcing, begin to
smoke or catch fi re.
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.
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 “. 0”. 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.
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.
• 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 Modifi cations: 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 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
or the grill heating element will turn on and off .
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 grill.
6. After 3 minutes, does the grill heating element become red?
Programme the oven to cook for 3 minutes using the convection
on 240°C.
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:
• Safety powerdowns:
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, Combi or
