What Auto
actually means.
Bosch wall hoods carry overheating protection. When the appliance gets too hot, the fan jumps to the highest level, even if the hood was off, and the display shows Auto. You cannot turn the speed down until the temperature drops; the hood then returns to your setting, or shuts off if it had been off.

What to do when Auto shows on the range hoodKind of codeHeat and grease sensors
A sensor inside the canopy has stopped telling the control a believable story: the heat sensor that starts the fan when the air above the burners gets hot, or on some hoods a sensor that reads grease or steam to set the speed. One that reads hot all the time keeps the blower running with the burners long cold; one that reads nothing leaves the automatic mode doing nothing. The sensor, its wiring and the canopy around it are checked at the visit.

Testing the sensor that starts the fan by itself when the burners get hot, so the hood starts when it should and stops when the heat is gone.
Shows up asReading a Range Hood Error Code or Blinking Light
A range hood error code may appear as letters and numbers on a display, a light that blinks in a pattern, a filter reminder that will not clear, or a beep with the fan refusing to start.

Bosch range hoods and downdraft vents get a home visit in which the touch controls and the fan's timed shut-off are checked before anything is opened.

Before you book,
in this order.
Each step comes from Bosch's own guidance for Auto on its range hoods. Follow it to the end: the last card says whether this is a visit.
Let the fan run at full speed; it is carrying heat away from the hood.
Turn down or switch off burners that are running very high, and do not leave a hot empty pan on the heat.
Wait for Auto to clear on its own once the hood cools.
If Auto shows up with only light cooking below, book a visit so the temperature sensing can be checked.

What not to do
Auto here is not an automatic mode you switched on; this hood's display uses the word for its overheating protection. Flames or smoke inside the hood are a fire, not this message, and need the burner off and the safety steps first.

Heat and grease sensors on other makes
Wall-mount range hood
The chimney hood fixed to a bare stretch of wall above the burners, its canopy catching the rising smoke while a telescoping cover hides the duct that climbs to the ceiling.
Under-cabinet range hood
The slim hood screwed to the bottom of the wall cabinet over the burners, venting up through that cabinet or back through the wall, or cleaning the air and returning it to the room.
Island range hood
The hood that hangs from the ceiling over burners set into a kitchen island, open on all four sides, with its duct and wiring hidden inside a chimney that drops from above.
In Bosch's own words
While the overheating protection is active, "Auto" appears on the display panel.

Still showing Auto?
Three things make the booking useful: the letters or blink pattern exactly as they showed, the full model number from the label behind the filters, and whether the fan still moves air on every speed. With those, the technician arrives with half the answer already worked out.
