  If no displays light up on your Bosch Hob, it could be due to a disconnected power supply. Check other electrical appliances to see if there's a power failure. Also, ensure the appliance is connected according to the circuit diagram. If these steps don't resolve the issue, it may be an electronics fault, and you should contact technical after-sales service.

Why did my Bosch DWB97CM50B/03 cooking zone switch off?

  Ryan ReyesAug 27, 2025
  If your Bosch Hob cooking zone switched off to protect the electronics, it is likely due to hot cookware being near the control panel. Remove the cookware, wait a few seconds, and touch any button. Once the fault display disappears, you can continue cooking.

How to prevent poisoning from flue gases with my Bosch Ventilation Hood?

  Always ensure adequate fresh air in the room if the appliance is being operated in exhaust air mode at the same time as a room air-dependent heat-producing appliance.

This document describes an extractor hood, a kitchen appliance designed to remove smoke, steam, heat, and airborne grease from the cooking area. It can operate in two main modes: exhaust air mode and circulating-air mode, each with specific installation and operational considerations.

Function Description

The primary function of the extractor hood is to maintain a clean and comfortable kitchen environment by extracting cooking fumes. In exhaust air mode, the appliance draws in air from the cooking area, filters it, and then expels it outside the building through a duct system. This mode is highly effective at removing odors and moisture. For optimal performance in this mode, the exhaust air duct should be as short and straight as possible, with a large diameter to minimize resistance and noise. It is crucial to ensure adequate fresh air supply in the room, especially if other room air-dependent heat-producing appliances (like gas or wood heaters) are operating simultaneously, to prevent the risk of flue gases being drawn back into the living space. A safety switch for the electricity supply to the hood is recommended in such cases.

In circulating-air mode, the appliance filters the extracted air through both a grease filter and an activated carbon filter, and then returns the cleaned air back into the kitchen. This mode is suitable when external venting is not possible or desired. While it effectively removes grease and odors, it does not remove moisture from the air. Different options for the activated carbon filter are available, and it's important to replace or regenerate these filters regularly to maintain effectiveness.

The extractor hood also features integrated lighting to illuminate the cooking surface, enhancing visibility during food preparation.

Usage Features

The appliance offers several operational modes and settings to suit different cooking needs:

Fan settings: The fan speed can be adjusted to various levels (e.g., 1, 2, 3) to match the intensity of cooking fumes. Higher settings are used for more vigorous cooking, while lower settings are suitable for lighter tasks.
Intensive mode: This mode provides a temporary boost in extraction power for particularly strong odors and fumes. After a set period (e.g., 6 minutes), the fan automatically switches back to the previously selected fan setting.
Lighting: The integrated lighting can be switched on and off independently of the fan operation, allowing users to illuminate the hob as needed.

To operate the appliance, users typically interact with a control panel that includes symbols for fan on/off, fan settings, intensive mode, and light on/off.

Maintenance Features

Regular maintenance is crucial for the efficient and safe operation of the extractor hood. Key maintenance tasks include:

Cleaning the metal grease filters: These filters capture grease particles and should be cleaned regularly to prevent fire hazards and maintain extraction performance. They can typically be removed and cleaned either by hand in hot soapy water or in a dishwasher. The frequency of cleaning depends on usage, but it is generally recommended every 2 months.
Replacing/cleaning mesh grease filters: If the appliance uses mesh grease filters, they should be cleaned or replaced as per the instructions.
Cleaning the appliance surfaces: The surfaces of the extractor hood, including stainless steel and painted surfaces, should be cleaned with appropriate cleaning agents to prevent damage and maintain appearance. Stainless steel surfaces should be cleaned in the direction of the grain, and abrasive cleaners should be avoided. Operator controls should not be cleaned with a wet cloth to prevent damage to electronic circuitry.
Replacing activated carbon filters: In circulating-air mode, activated carbon filters absorb odors and need to be replaced or regenerated periodically, as they lose their effectiveness over time.
Replacing bulbs: Faulty bulbs should be replaced promptly to prevent overloading of the remaining bulbs and ensure adequate lighting.
Checking for damage: Users should regularly inspect the appliance for any signs of damage, especially to the power cable, and contact customer service if any issues are found. Incorrect repairs can be dangerous and should only be carried out by trained technicians.

The manual also emphasizes safety precautions during maintenance, such as disconnecting the appliance from the power supply before cleaning or repairs, and wearing protective gloves when handling components with sharp edges.
