IMPORTANT SAFETY INSTRUCTIONS

There is a seal around the oven interior which seals the inside of
the door. Take care not to rub, damage or move the gasket.

Do not use oven cleaners. Commercial oven cleaners or oven
liners of any kind should not be used in or around any part of the
oven.

The back panel can be removed for cleaning purposes (see
"Cleaning and care"). Ensure it is correctly fitted after cleaning and
never operate the oven without the back panel fitted.
Accessories

Use only genuine original Miele spare parts. If spare parts or
accessories from other manufacturers are used, the warranty may
become void.
