Frequently Asked Questions - C24MR21G0B NEFF
How do I set the microwave power level?
Press the Microwave button, then turn the rotary selector to choose the desired power level (e.g., 900 W). Confirm with Start.
Can I use aluminum foil in this oven?
Yes, but only in combination mode and without covering the entire rack. Keep foil at least 3 cm away from the oven walls and never use it in pure microwave mode.
How do I clean the oven cavity?
Use the ActiveClean function: pour 400 ml of water into a heat-resistant dish, select ActiveClean, and let the cycle run. Wipe away softened residue afterwards.
What types of cookware are microwave safe?
Use glass, ceramic, and microwave-safe plastic containers. Avoid metal and dishes with metallic trims. Check for a microwave-safe symbol on the bottom.
How do I activate the child lock?
Press and hold the Lock button for 3 seconds. A symbol appears on the display, and all functions are disabled until you release the lock.
Why does the oven make a humming noise during operation?
Humming is normal, especially in microwave mode, as the magnetron converts electricity. If you hear clicking or grinding, stop the oven and contact support.
How do I replace the internal light bulb?
Disconnect the oven from the mains, unscrew the bulb cover inside the cavity, and replace the bulb with the same type (e.g., E14, 25 W). Reassemble and reconnect.
Is it safe to use steam cooking with hard tap water?
For models with a steam inlet, use distilled or demineralized water to prevent limescale buildup. If you use tap water, run the descaling cycle regularly.
What does error code E011 mean?
Error E011 indicates a sensor fault in the temperature probe. Turn the oven off and on again. If the error persists, contact NEFF customer service.
How do I set a delayed start?
Select a cooking function, press Delay, set the desired end time using the rotary selector, and confirm. The oven will start automatically so that it finishes at that time.
