Problem solving guide

Installation, maintenance and repairs may only be carried out by suitably qualified and competent persons in accordance with local and national safety regulations.

Repairs and other work by unqualified persons could be dangerous, and the manufacturer will not be held liable for unauthorised work.

Ensure current is not supplied to the appliance until after maintenance or repair work has been carried out.

Some minor problems can be corrected without contacting the Miele Service Department.

What to do if . . .

. . . the oven does not heat up

Check whether,

^the function selector and the temperature selector have been set at the function and temperature required.

^the mains fuse has tripped. If it has, contact a qualified electrician or the Miele Service Department.

.. the heating works but not the oven lighting

The lamp needs changing.

^Disconnect the appliance from the electricity supply. Switch off and unplug at the socket, or remove the fuse, or switch off at the isolator as appropriate.

Depending on model, the light is either in the oven roof or in the right side wall.

Light in the roof:

^Unscrew the lamp cover and the seal.

^Change the lamp.

When purchasing a new lamp, take the old one with you to make sure you obtain the correct replacement (230 V, 25 W, E 14, heat resistant to 300 °C).

^Screw the lamp cover and the seal back on again.

Reassemble in the reverse order, carefully ensuring all parts are correctly in place.
