Bosch Serie 6 BFL524MB0 20L Built-in Microwave with Grill, 800W, Black

Want a microwave with a grill that sits neatly inside your kitchen units? Is the Bosch Serie 6 Built-in Microwave the right fit for your kitchen?

This 20L black microwave with grill is designed to be built into a kitchen unit, with a clean glass front and a side control panel.

It offers 800W of microwave power and a grill for browning, with a connected load of 1270W.

Why Choose the Bosch Serie 6 Built-in Microwave

A rotary dial and touch controls make it simple to set the power and cooking time, and the display shows the clock when it is not in use.

It suits a wall unit or a tall housing, so it can sit at eye level or above a built-in oven.

A microwave earns its place by warming leftovers, defrosting and cooking simple meals without heating up the main oven.

Capacity matters: around 20 litres suits singles and couples, while 25 litres or more gives room for larger plates and family dishes.

Before you choose, check the space you have and whether you want a freestanding model or one built into your kitchen units.

Key Features

• Microwave and grill: 800W of microwave power plus a grill for browning and crisping.
• Built-in design: Made to fit inside a kitchen unit for a flush, fitted look.
• Simple controls: A rotary dial and touch keys set the power, time and grill.
• 20L cavity: Room for everyday plates, bowls and reheating family portions.

Tips for Use and Fitting

Check the size of your kitchen unit against the installation dimensions before you order, including the depth behind the opening.

This is a built-in appliance for building into a kitchen unit. Fitting is carried out by the buyer or their installer, and is not included.

Use only microwave-safe dishes, never metal, and stir or turn food halfway through so it heats evenly.
