What This Guide Helps With

This guide helps troubleshoot Valve Error alarms on the Cardinal Health Kangaroo OMNI feeding pump. This alarm can stop feeding when the pump detects valve actuator resistance, blockage, contamination, misorientation, cassette seating problems, or feeding set issues.

A Valve Error should be treated as a delivery-interrupting condition because the pump may be unable to control flow correctly until the cassette and valve actuator area are inspected and corrected.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• If the Kangaroo OMNI is connected to a patient and the Valve Error alarm is active, confirm feeding has stopped and notify clinical staff.
• Do not continue troubleshooting while the patient depends on this pump for uninterrupted nutrition or hydration.
• Move the patient to another verified feeding pump if feeding must continue.
• Expected outcome: Patient feeding is safely supported before troubleshooting continues.
• Why it matters: A valve-related alarm can interrupt delivery and should not be bypassed or repeatedly cleared without confirming the cause.

Verify the Reported Alarm and Behavior

• Look at the pump display and confirm the alarm is specifically: Valve Error.
• Confirm whether the alarm occurs immediately after cassette loading, after pressing Start or Continue, during feeding, intermittently after pump movement, or only with a specific feeding set.
• Observe whether the pump stops feeding, will not restart, or alarms again within a few seconds.
• Expected outcome: The Valve Error is confirmed and the failure timing is understood.
• Why it matters: This confirms a true valve actuator condition rather than a general feed, tube, or cassette-loading issue.

Translate the Alarm Into the Real-World Condition

• The Valve Error alarm means the pump detected unusual resistance at the valve actuator or the actuator is not positioned correctly.
• Check for cassette seating issues, feeding set valve binding, debris, dried formula, contamination near the actuator, actuator misorientation, damaged feeding set material, or a pump-side valve mechanism problem.
• Expected outcome: Troubleshooting focuses on the valve actuator and cassette interface.
• Why it matters: The pump is detecting that the valve mechanism cannot move or position normally.

Remove the Cassette

• Stop the pump and remove the cassette from the Kangaroo OMNI.
• Inspect the cassette and the area where it interfaces with the valve actuator.
• Check for improper cassette seating, bent or distorted set material, dried feeding solution, sticky residue, visible obstruction, or fluid contamination.
• Expected outcome: Cassette and valve area are free of visible obstruction or damage.
• Why it matters: A poorly seated or contaminated cassette can create resistance and trigger the alarm.

Inspect the Valve Actuator

• Check the valve actuator for blockage, residue, or abnormal position.
• Confirm the actuator appears correctly oriented and is not stuck, tilted, obstructed, or contaminated.
• Do not force the actuator or perform internal disassembly.
• Expected outcome: Valve actuator is clean, dry, unobstructed, and correctly oriented.
• Why it matters: The alarm specifically indicates unusual actuator resistance or incorrect actuator orientation.

Clean and Dry the Valve Actuator Area

• Clean the valve actuator area using approved facility cleaning practices for the Kangaroo OMNI.
• Remove dried formula, feeding solution, or contamination from the actuator region.
• Allow the area to fully dry before reloading the cassette.
• Expected outcome: Valve actuator area is clean and dry before retesting.
• Why it matters: Moisture or sticky enteral solution can interfere with actuator movement and cassette recognition.

Reload the Cassette Correctly

• Reload the cassette into the pump.
• Confirm it is fully seated and aligned before restarting the pump.
• Press Continue if prompted, then attempt to restart feeding using a safe test setup or approved clinical workflow.
• Expected outcome: The pump accepts the cassette and resumes operation without the Valve Error alarm.
• Why it matters: Correct cassette seating is a common external cause of valve actuator resistance alarms.

Replace the Feeding Set

• If the Valve Error returns, replace the feeding set with a new compatible set.
• Prime and load the new set correctly.
• Disconnect from the patient before priming if priming is required.
• Restart feeding or test operation.
• Expected outcome: Alarm clears when a defective or misloaded feeding set is replaced.
• Why it matters: A damaged cassette or set can bind at the valve interface even when the pump itself is functional.

Try a Different Kangaroo OMNI Pump

• If the Valve Error continues after cleaning, drying, reloading, and replacing the feeding set, use a different Kangaroo OMNI pump for patient feeding.
• Remove the original pump from service.
• Expected outcome: Patient feeding continues on a known-good pump.
• Why it matters: Continued Valve Error alarms after external causes are ruled out suggest a pump-side valve actuator issue.

Stop When Resolved

• If cleaning, proper cassette loading, or feeding set replacement clears the alarm, verify normal pump operation before returning the device to service.
• Confirm that no Valve Error alarm returns, the cassette remains seated correctly, feeding starts normally, the pump display and buttons respond normally, and no unusual sounds or binding are observed.
• Expected outcome: Device operates normally and can be returned to service.
• Why it matters: The alarm should be corrected and verified before clinical reuse.

If the Problem Persists

If the Valve Error alarm continues after the cassette is removed, the actuator is inspected, cleaned and dried, the cassette is reloaded, and the feeding set is replaced, external and common causes have been ruled out.

Persistent Valve Error alarms may indicate a device-side valve actuator or internal pump mechanism failure.

The pump should be removed from service, labeled Out of Service, and sent for repair or bench evaluation.

Do not keep clearing the alarm and returning the pump to clinical use.

Clinical Use Tip

Never troubleshoot a Valve Error on an active patient while feeding delivery is required. Move the patient to a backup feeding pump first, then evaluate the cassette, actuator, and feeding set. Avoid relying on a pump with unresolved valve actuator alarms.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Kangaroo OMNI feeding pump reported Valve Error alarm. Staff stated pump stopped feeding and alarm returned after attempting to continue."

Cause

What was observed during troubleshooting.

Example:
"Valve actuator area found with dried feeding solution and possible cassette binding. Alarm cleared after cassette removal, actuator cleaning/drying, and proper cassette reload."

Resolution

What action was taken.

Example:
"Removed cassette, inspected valve actuator for obstruction and orientation, cleaned and dried valve actuator area, reloaded cassette, and verified pump resumed operation without Valve Error alarm. Device returned to service after functional check."

Helpful Details to Include (If Known)

• Alarm behavior
• Accessories swapped
• Power behavior
• Environmental factors
• Indicator lights
• Final device status

Final Thought

The Valve Error alarm should be treated as a delivery-interrupting condition. Start with patient safety, confirm the alarm, inspect the cassette and valve actuator area, clean and dry the actuator, and replace the feeding set if needed. If the alarm continues after these checks, remove the pump from service and escalate for repair. Accurate CCR documentation helps show what was tested, what was corrected, and why the final device status was appropriate.

That is successful troubleshooting.
