Sparking
1. Burnt on food
debris
Spillages or splashes can burn and catch fire, all food that is
put into the microwave should be appropriately covered. All
spillages or splashes must be cleaned, and all areas of
microwave cleaned after each use. Burnt on food debris in
the microwave, on the waveguide and the behind the
waveguide can cause the microwave to 'spark'. This is
because burnt on debris can be focused on by the
microwaves and spark. Microwaves must be thoroughly
cleaned after every use to ensure no food is burnt on to any
part of the microwave. If the microwave does 'spark' the
waveguide must be disposed, the microwave must be cleaned
thoroughly and then contact customer services for a
replacement wave guide. The replacement wave guide should
be fitted and the microwave should operate normally.
However, if the microwave 'sparks' again on first use (after
the waveguide has been replaced and the microwave
cleaned,) please contact customer services for further advice.
2. Metal or foil
No metal or foil should be put inside a microwave as it can
cause 'sparking' which can damage the microwave. The only
metal accessories that should be used inside the microwave
are the ones supplied by the manufacturer.
3. Pressure build up in
food
Food with none porous skins (potatoes for example), must be
pierced to allow steam to escape. As the build up of pressure
can cause food to burst and create a 'fire hazard‘.
Heat spots
Operated empty or
with no moisture
Microwaves cannot be run empty, microwaves need moisture
to operate correctly. If microwaves are operated empty or are
used to heat up plates (this is not permitted), the microwaves
can focus on a single point inside the microwave. This can
cause a heat spot, which can cause the area to become
deformed, warped or start to melt. If microwaves are
operated empty or to heat up foreign objects this will void
the warranty.
