The fan button on your Candy CCE119/1X hood has a backlight that indicates its status. When the button is activated (pressed), the backlight turns on simultaneously: this is the main visual indicator that the fan is operating. If the backlight of the button is off, it means that the fan is disabled.
Depending on your hood model, you have several possible configurations. If your hood has three distinct buttons (Button 1, Button 2, Button 3), the backlight of one of these buttons will indicate which speed level is currently active. Button 1 corresponds to low speed, Button 2 to medium speed, and Button 3 to high speed. When you press a button to activate the fan, its backlight will illuminate immediately.
If your model has a Power/Off button with a digital display, the backlight of this main button will also indicate activation. Additionally, the digital screen will display the current speed level (1 for low speed, 2 for medium speed, 3 for high speed, or 4 for the Booster function depending on your configuration). To turn off the fan, press the active button again: the backlight will turn off and the fan will stop operating.
In summary, the backlight of the button is the main visual indicator to know if the fan of your Candy CCE119/1X hood is on or off. A lit backlight = fan on, backlight off = fan off.
