Published on 27 July 2026

You have pressed the power-on button (unintentionally) before you plugged in the appliance.

When you press the power-on button before you put the plug in the wall socket, the sterilizer starts operating immediately when you plug it in.

Warning: The appliance becomes extremely hot during sterilization and may cause burns if you touch it.

Always check if the sterilizing light is on, this is an indication that the appliance is already operating.

Below are other frequently-asked questions to help you with your appliance.

My Philips Avent sterilizer's cycle lasts longer than usual

The sterilizing process may take longer than usual because you poured too much water into the sterilizer.

To ensure accurate sterilization you should follow the following instructions:

Instructions

Measure and pour exactly 100ml/3.5 oz. of pre, fresh water directly into the water reservoir
Make sure all parts that need to be sterilized are completely disassembled and place them in the basket with their openings pointing down to prevent them from filling up with water
When you fill the small basket:
Put the nipples on the bottom of the basket
Place the screw rings loosely on top of the nipples
Clip the bottle dome caps into the holders

My Avent sterilizer shows an orange light

The sterilizing light shows orange to indicate that it has started operating.

My new Philips Avent sterilizer smells when I unpack it

When you unpack the sterilizer, you may notice a strange smell. This smell is not harmful. Due to the newness of the materials the appliance will produce a slight smell when you take it out of the box.

This smell will soon disappear after you have unpacked your sterilizer. We also recommend that you complete one sterilizing process with empty baskets to remove any remaining dirt and smell.
