Troubleshooting

several things:

the yellow valve.
• Verify that yellow valve on breastpump kit is fitted correctly into the
breastshield connector.

Breastpump Troubleshooting
• Make sure breastpump is plugged in.
• Check and secure all connections of kit and breastpump.
• Ensure that the pale yellow ends of the tubing fit securely into
connectors and the triangular two-tone yellow ends into the
membrane caps. (Refer to Symphony kit assembly instructions.)
• Inspect Symphony membranes. If membranes appear to be worn or
have a tear they need to be replaced (Article # 8200094).

Breastpump Troubleshooting
• Make sure the stem assembly on the
pump handle is seated all the way
into the pump body until it will go no
further. Make sure the white o-ring is in
place in the stem handle.
• Make sure the oval base of the stem is
properly seated in the oval base of the
diaphragm.
• Finally, make sure the diaphragm is pushed all the way onto the
circular rim on the underside of the handle.
• If pump handle does not release smoothly or sticks, check
diaphragm assembly to correct. (Refer to step 6 of the Harmony Kit
Assembly Instructions on page 4.)
