9.3 Cleaning the burners

After each use, clean the surface of the burner parts.
This prevents food remains from burning on.

The burner parts can be damaged if you clean them in
a dishwasher.

Do not clean the burner parts in a dishwasher.

Note: 

Read the information on the cleaning agents.

Allow the appliance to cool down.

2.

Clean using a non-metallic brush and soapy water.

3.

Let the appliance dry completely. If there are water
droplets or damp areas at the start of cooking, this
may damage the enamel.

Insert the burner parts. Ensure that the burner caps
are correctly positioned on the flame spreader.

1.

Allow the appliance to cool down.

2.

Carefully remove the pan supports.

3.

Clean using a non-metallic brush and soapy water.
Carefully clean the area around the rubber pads. If
the rubber pads come loose, the pan support may
scratch the hob.

Alternatively, you can clean the pan supports in the
dishwasher.
Use the cleaning agents recommended by the dish-
washer manufacturer. In the case of heavy soiling,
we recommend precleaning the pan supports.

5.

Let the appliance dry completely. If there are water
droplets or damp areas at the start of cooking, this
may damage the enamel.

6.

Insert the pan supports correctly.
