Kitchen furniture

Oven housing units from virtually all lines of kitchen furniture are suitable for installing the built-in oven. However, the veneers or plastic laminates on the housing unit must be applied with heat-resistant glue (90 °C). If plastic laminate or glue are not sufficiently heat-resistant, warping, bubbling or detachment of the finish may result.

Installation without cupboard

Installation of the built-in oven

❑ To burn-in the insulation, heat up the oven prior to installing the unit.

❑ Push the built-in oven into the housing unit and align the unit until it is in a level position.

❑ Open the oven door and, using one screw on each side, fasten the built-in oven to the side strips of the housing unit (see illustration). The two screws (supplied with the builtin oven) must be started slightly outward.

❑ Verify that the built-in oven is positioned securely and in a level position, and that the required installation dimensions have been maintained.

❑ The properly installed appliance must be covered on all sides in such a fashion that not even components with rough insulation are exposed to the touch. The cover must be removable with tools only.

Maintenance

How do I change my oven bulb?

Most of our ovens use an E14 bulb. A special pack can be ordered from us which includes an E14 bulb and special tool to remove the bulb cover. Always make sure the oven is switched off and cold before replacing the bulb. The tool includes locating lugs to grip the cover. It can then be loosened by twisting and removed. This is a good opportunity to clean the bulb cover. The E14 bulb can then be changed and the cover replaced.

How do I clean my oven's fiberglass gasket?

Do not clean the fiberglass gasket.

How do I clean my oven's flat rack?

Wash with hot, soapy water and a soft cloth, rinse and then dry. Do not clean the rack in the self-cleaning oven. If flat racks are cleaned in the oven during the self-cleaning mode, they will lose their shiny finish and may not glide smoothly. If this happens wipe the rack edges with a small amount of vegetable oil, then wipe off.

How do I clean my oven's glass surfaces?

Wash with hot, soapy water and a soft cloth, rinse and then dry or use a glass cleaner.

How do I clean my oven's grill pan and grid?

Wash with hot, soapy water and a soft cloth, rinse and then dry. Do not clean the grill pan and grid in the oven during self-cleaning mode.

How do I clean my oven's painted surfaces?

Wash with hot, soapy water and a soft cloth, rinse and then dry. Do not use powder cleaning agents, steel wool pads, oven cleaners and other abrasive cleaning materials.

How do I clean my oven's telescopic racks?

Wash with hot, soapy water and a soft cloth, rinse and then dry. Avoid getting cleansing powder or residue in the telescopic slides. Re-lubricate the telescopic slides as needed by using high-temperature food-grade lubricants. Do not clean the rack in the oven during self-cleaning mode.

How do I use E-cloths?

Dusting: Use the green cloth dry for dusting. The static will pick up the dust particles. Cleaning grease and dirt: Fold the green cloth and use damp to remove any grease and dirt.

Glass cleaning and polishing: Lightly spray water on the blue cloth and wipe appliance with the cloth.

Stainless steel: Wet the green cloth and wipe away any grease. Spray the surface with water and polish with the blue cloth. Always wipe in the direction of the grain. Always make sure your cloths are clean to avoid scratching surfaces. E-cloths (part # 00466148) can be purchased in the Bosch online accessories store.

How should I protect stainless steel surfaces from marking?

You can treat the surface with a tested and approved oil impregnated Conditioning Cloth (can be ordered from us) will assist fingerprint and mark resistance. Some people use baby oil or similar products on stainless steel. However, these products do not work as they attract dust and fluff, causing a residue to form. The same Conditioning Oil as in the cloths can be ordered in a bottle from us. It is food-safe and can be used on surfaces which are in contact with food.

How to activate the oven’s self-cleaning process?

Note: Applicable for models with self-cleaning function only.

Please refer to the user manual to check if your oven has a self-cleaning function. If yes, follow the instructions in the user manual to activate the self-cleaning process. Before doing so wipe away spills, pools of oil, and excessive debris with a cloth. Those may cause smoke mission and possibly be a fire risk. Do not clean oven parts or accessories in the self-cleaning oven. The light in the oven cannot be turned on during the self-cleaning process. The special heat-resistant enamel and the polished components in the oven may become discoloured over time. This is normal and does not affect operation. Do not use scouring pads, abrasive cleaners or cleaners with high alcohol content, as they might damage the oven. Remove all accessories, racks and broiling pans before activating the self-cleaning process. In double ovens, the self-cleaning process is only available for one oven at a time.

How to remove grease from stainless steel surfaces?

Remove any deposits with our tested and approved Stainless Steel Cleaning Powder. This will remove dirt and spillages without damaging the surface. Make sure the powder is used on a damp cloth as a ‘paste’ and wipe along the grain of the metal. This product can be ordered from us.

Rust on the appliance

• Rust
  • Reason: Fat or other residue appears as corrosion.
  • Solution: Clean the appliance with detergents recommended in the instruction manual.
• Rust on stainless steel surface
  • Reason: Stainless steel surfaces have been cleaned incorrectly.
  • Solution: Read the instructions for care in the instruction manual. To ensure the stainless steel surface does not rust, it is important to always clean stainless steel surfaces in the polishing direction. Use a mild cleaning agent when doing so. Never use caustic or abrasive cleaning agents. Please visit our store to buy tested and approved products. Do not use stainless-steel cleaning agents on the controls. Use a damp cloth and a mild detergent. Dishcloths may contain salts. They encourage rust. Always rinse out new dishcloths and sponges thoroughly. Set aside a special cloth for stainless steel surfaces. If you use e.g. the same cloth for your iron pans and stainless steel surfaces, there is the risk of rust forming. Once rust has formed, it can no longer be removed.

Malfunction

Condensation or humidity

• Condensation in the cooking compartment
  • Reason: When baking cakes which have a very moist coating or cooking a joint, condensation may occur.
  • Solution: Open and close appliance door while cooking.
