Frequently Asked Questions - KOB20721XK ZANKER

How do I preheat the oven for first use?

How do I clean the oven glass door?

Remove the oven door completely (see manual). Release the locking system, turn the two fasteners 90°, and lift out the inner glass panel. Clean with water and mild soap, dry, and reinstall. Do not use abrasive cleaners or dishwasher.

What should I do if the oven does not heat up?

Check if the oven is activated and the fuse is not blown. If the fuse blows repeatedly, contact a qualified electrician. Refer to troubleshooting section in manual.

How to replace the oven lamp?

Oven function

Application

Moist Baking

This function is designed to save energy during cooking. For the cooking instructions refer to "Hints and tips" chapter, Moist Baking. The oven door should be closed during cooking so that the function is not interrupted and to ensure that the oven operates with the highest energy efficiency possible. When you use this function, the temperature in the cavity may differ from the set temperature. The heating power may be reduced. For general energy saving recommendations refer to "Energy Efficiency" chapter, Energy Saving. This function was used to comply with the energy efficiency class according to EN 60350-1.

Setting a heating function

1. Turn the knob for the heating functions to select a heating function.
2. Turn the control knob to select the temperature. The lamp turns on when the oven operates.
3. To turn off the oven, turn the knob for the heating functions to the off position.

Pure technical line drawing of a mechanical component or bracket (no text or symbols)

Cooling fan

When the oven operates, the cooling fan turns on automatically to keep the surfaces of the oven cool. If you turn off the oven, the cooling fan can continue to operate until the oven cools down.

Hints and tips

Safety thermostat

Incorrect operation of the oven or defective components can cause dangerous overheating. To prevent this, the oven has a safety thermostat which interrupts the power supply. The oven turns on again automatically when the temperature drops.

Warning! Refer to Safety chapters.

The temperature and baking times in the tables are guidelines only. They depend on the recipes and the quality and quantity of the ingredients used.

Cooking recommendations

The oven has four shelf positions.

Count the shelf positions from the bottom of the oven floor.

Your oven may bake or roast differently to the oven you had before. The below tables provide you with the standard settings for temperature, cooking time and shelf position.

If you cannot find the settings for a special recipe, look for the similar one.

The oven has a special system which circulates the air and constantly recycles the steam. With this system you can cook in a steamy environment and keep the food

soft inside and crusty outside. It decreases the cooking time and energy consumption.

Baking cakes

Do not open the oven door before 3/4 of the set cooking time is up.

If you use two baking trays at the same time, keep one empty level between them.

Cooking meat and fish

Leave the meat for approximately 15 minutes before carving so that the juice does not seep out.

To prevent too much smoke in the oven during roasting, add some water into the deep pan. To prevent the smoke condensation, add water each time after it dries up.

Cooking times

Cooking times depend on the type of food, its consistency, and volume.

Initially, monitor the performance when you cook. Find the best settings (heat setting, cooking time, etc.) for your cookware, recipes and quantities when you use this appliance.

Care and cleaning

Warning! Refer to Safety chapters.

Notes on cleaning

Clean the front of the oven with a soft cloth with warm water and a mild cleaning agent.

To clean metal surfaces, use a dedicated cleaning agent.

Clean the oven interior after each use. Fat accumulation or other food remains may result in a fire.

Energy saving

The oven contains features which help you save energy during everyday cooking.

General hints

Make sure that the oven door is closed properly when the oven operates. Do not open the door too often during cooking. Keep the door gasket clean and make sure it is well fixed in its position.

Use metal dishes to improve energy saving.

When possible, do not preheat the oven before you put the food inside.

Environmental concerns

When the cooking duration is longer than 30 minutes, reduce the oven temperature to minimum 3 - 10 minutes before the end of the cooking time, depending on the duration of the cooking. The residual heat inside the oven will continue to cook.

Use the residual heat to warm up other dishes.

Keep breaks between baking as short as possible when you prepare few dishes at one time.

Cooking with fan

When possible, use the cooking functions with fan to save energy.

Keep food warm

Choose the lowest possible temperature setting to use residual heat and keep a meal warm.

Moist Baking

Function designed to save energy during cooking.
