    How to clean a Philips Avent Combined Steamer and Blender and fix common issues

    Published on 27 July 2026

    Wash the parts that have come into contact with food in hot water with liquid soap. All parts, except the motor unit, can also be cleaned in the dishwasher. Never immerse the motor unit in water. If necessary, clean it with a moist cloth.

    You are advised to pre-rinse the parts under tap water before putting them into the dishwasher for best results.

    Cleaning the water tank

    In case some food ingredients wrongly entered the water tank, it might happen they get stuck to the heating element in the water tank and can't be removed by only rinsing the water tank. Please follow these steps to clean the water tank:

    1. Make sure the appliance is switched off and unplugged.
    2. Add one sachet of citric acid (10g) to 200ml of warm water; you can also use a solution of 150 ml water and 50 ml of white vinegar (8%).
    3. Fill the water tank with the descaling solution; use the measuring cup; do not fill the water tank directly from the water tap.
    4. Close the lid of the water tank.
    5. The jar (without food inside) needs to be in steaming position.
    6. Plug the appliance back in and turn the control knob to the steaming position; the steaming light lights up orange to indicate that the appliance is steaming.
    7. Switch off the appliance after 5 - 6 minutes of steaming and unplug it; approximately 150ml water remains in the water tank.
    8. Pour the remaining used solution out of the water tank.
    9. Rinse the tank thoroughly with fresh water several times.
    10. Fill the tank with 200ml water and run two complete steaming cycles without any food in the jar (until the appliance switches off automatically) before you use the appliance again; make sure to wait for 10 minutes between each steaming cycle.
    11. Check if the water tank is completely empty from water and leave the lid open to avoid bacterial growth.

    Food residuals/mold has built up in my Philips Avent Combined Steamer and Blender

    To prevent the buildup of food residuals or mold:

    • All parts must be separated and cleaned immediately after use
    • All parts must be completely dry before assembly after cleaning

    Food or mold has built up in parts of the appliance

    Immerse the parts in warm soapy water for about half an hour to soften the residuals and remove them using a brush.

    My Avent Combined Steamer and Blender won't steam

    If your Philips Avent Combined Steamer and Blender does not steam or does not steam properly, we are here to help. Just follow these steps to resolve it yourself.

    Easy fix

    There can be several reasons why the steam function does not work (properly):

    • There is too much limescale in the water tank. Regularly descale your appliance every 2-4 weeks to prevent buildup.
    • After one steaming cycle, the device needs about 10 minutes to cool down until a new steaming cycle can be started. Try again after 10 minutes.
    • Make sure you have positioned the jar in the right way (steaming position).

    Still not working?

    If the steam function is still not working it could be that the safety switch is defect. Please contact us.

    The Philips Avent Steamer and Blender will not switch on

    If the Philips Avent Steamer and Blender will not switch on, it may be because:

    • The blade unit is blocked, because there is too much food in the jar. Switch off the appliance and process a smaller quantity; Do not let the device blend for more than 30 seconds.
    • The jar is in steaming position. Turn the jar upside down and start blending.

    My Philips Avent Steamer & Blender jar is leaking

    If you the jar is leaking, this may be because:

    • You might have not assembled the lid properly on the jar. Assemble the lid properly on the jar. 
    • There is too much food in the jar. Switch off the appliance and process a smaller quantity.

    My Avent Steamer & Blender makes noise while blending

    The sieve may not attached to the lid of the jar. Make sure the sieve is attached to the lid of the jar.

    Steam escapes my Philips Avent Steamer & Blender water tank

    Most commonly, steam escapes the Philips Avent Steamer & Blender water tank because:

    • The lid of the filling opening is not closed properly. Close the lid of the filling opening until you hear a clear click.
    • The steam outlet is blocked by food or by limescale. Clean the steam outlet with a pointed object without damaging the seal.

    My Philips Avent Steamer & Blender control knob moves while blending

    This is normal, you need to hold the control dial in blending position to blend. This is a regular safety feature enabling you to control the blending process.

    My Philips Avent Combined Steamer and Blender smells

    During the first times of use this unpleasant smell is normal. If the appliance continues to give off this smell after you have used it a few times, check if the processing quantity and processing time are correct. Process small quantities and do not let the appliance blend for more than 30 seconds at a time.
