Troubleshooting
It may happen that the appliance does not function properly

check if anything can be done. First, check to see that there
are no interruptions in the gas and electrical supplies, and,
in particular, that the gas valves for the mains are open.

around the burner.
Check whether:
• The gas holes on the burner are clogged.
• All the movable parts that make up the burner are
mounted correctly.
• There are draughts near the appliance.
The flame dies in models with a safety device.
Check to make sure that:
• You pressed the knob all the way in.
• You keep the knob pressed in long enough to activate
the safety device.
• The gas holes are not blocked in the area corresponding
to the safety device.
The burner does not remain lit when set to minimum.
Check to make sure that:
• The gas holes are not blocked.
• There are no draughts near the appliance.

The cookware is unstable.
Check to make sure that:
• The bottom of the cookware is perfectly flat.
