Troubleshooting guide
• Check that all pump parts have been assembled correctly and that the valve is positioned correctly.
• Ensure that the silicone diaphragm and let-down massage cushion™ are fitted securely to the pump body and a perfect seal is created.
• Make certain that the tubing connections and control handle are firmly in place.
• Ensure the pump is correctly assembled and that suction is being created.
• Relax and try again, as expression may improve after practice.
• Refer to the ‘Hints to help you succeed’ section on page 14 of the instruction booklet.
• You may be squeezing too hard. You do not need to use all the suction the pump can generate.
• Try squeezing the handle more gently and remember the 2-3 second pumping rhythm.
• Consult your health professional/breastfeeding advisor.
• Remove and re-fit the let-down massage cushion to ensure it is firmly attached and pushed far enough down the centre of the funnel.
• Try leaning slightly forward.

CONCERN SOLUTION
• Avoid contact with antibacterial detergents/cleaners as they can damage the plastic. Combinations of detergents, cleaning
products, sterilising solution, softened water and temperature fluctuations may, under certain circumstances, cause the plastic
to crack. If this occurs, do not use. The pump bodies and breast milk containers are dishwasher safe but food colourings may
discolour them. Follow guidelines in ‘How to clean and sterilise your ISIS iQDUO’ on pages 5-6 of the instruction booklet.
