My Philips Avent electric breast pump has low or no suction

Always use the original power adapter or charging cable that came with your pump. If you’ve purchased a newer model that didn’t include a power adapter, check your pump’s user manual and make sure the charging accessories match the recommended specifications.

For some Philips Avent electric breast pumps, a worn or older power adapter can affect the performance.

If you are using an older adapter version, contact Philips Consumer Care Center to check if a free-of-charge replacement is available.

The valve is the key to keeping good suction. It helps create the vacuum needed for effective milk expression.

Check that:

• The valve is fully closed when not in use
• The valve is not damaged, stretched, or misshapen
• During pumping, the pointed end of the valve does not open excessively

If the valve looks damaged or does not close fully, replace it.

Check:

• Valves
• Membranes
• Breast cushions
• Breast shields
• Inserts (if you use them with your breast pump)

Look for:

• Cracks
• Tears
• Holes
• Deformation
• Worn-out parts

If any part looks damaged or worn out, replace it.

Even a small air leak can reduce suction.

Make sure that:

• All parts are connected securely
• The pump is correctly assembled as described in the user manual
• Only Philips Avent parts are used
• Parts from different pump models are not mixed together

If possible, assemble the pump while the disinfected parts are still slightly moist. This can help make a better seal.

Milk residue or damaged parts can affect how well your pump works.

Before first use and after every pumping session:

• Disassemble all parts that come into contact with the breast and breast milk
• Clean and disinfect them as described in the user manual
• Handle the valve carefully

To clean the valve:

• Wash it gently in warm water with a small amount of dishwashing liquid
• Rub it gently between your fingers
• Do not insert any object into the valve

The suction level may be set too low.

Gradually increase the suction to a higher level, but still comfortable.

Use the highest setting that feels comfortable and does not cause pain.

If your breast shield or insert isn’t the right size, it can make pumping less effective.

Signs of poor fit include:

• Little or no milk output
• Discomfort during pumping
• Excessive nipple rubbing

Before pumping:

• Apply a warm towel to your breast

This may help start the let-down effect and support the milk flow.
