Miele TX2070 Operating Instructions Manual page 13

~
The appliance must be disconnected from the mains electricity
supply before repairs, cleaning and maintenance work is carried
out. The appliance is only completely isolated from the electricity
supply when:
– it is switched off at the wall socket and the plug removed,
– the mains fuse is disconnected,
– or the screw-out fuse is removed (in countries where this is
applicable).
~
Faulty components must only be replaced by genuine Miele
original spare parts. The manufacturer can only guarantee the safety
of the appliance when Miele replacement parts are used.
~
Appliances which are built-in behind a furniture door must only be
operated when the door is open. Do not close the furniture door
when the appliance is in operation. Heat and moisture would build
up behind a closed furniture door, potentially causing damage to the
microwave oven and the furniture unit. Wait until the appliance has
cooled down completely before closing the furniture door.
