What This Guide Helps With

This guide helps troubleshoot the Cassette Error alarm on the Cardinal Health Kangaroo OMNI feeding pump. This alarm may occur when the pump detects an unusual cassette operating condition, a cassette loading problem, disposable feeding set irregularity, contamination near the cassette area, or a pump-side cassette detection issue.

A Cassette Error may interrupt feeding delivery or prevent the pump from running reliably. Because enteral feeding accuracy and continuity matter, troubleshooting should begin with patient safety and simple external checks before removing the pump from service.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• If the pump is connected to a patient and the Cassette Error alarm is active, confirm feeding has stopped or is unreliable.
• Do not continue repeated troubleshooting on an active patient setup.
• Transfer feeding to another known-good pump if nutrition delivery must continue.
• Expected outcome: The patient is not dependent on a pump with an unresolved cassette-related alarm.
• Why it matters: A cassette error may prevent accurate or continued feeding delivery.

Verify the Reported Alarm and Behavior

• Confirm the display shows Cassette Error.
• Ask staff when the alarm occurred, such as during startup, after loading the set, shortly after feeding begins, intermittently during feeding, or only with one specific feeding set.
• Note that alarm detection may take longer at very low flow rates and may be faster at higher flow rates.
• Expected outcome: The alarm is reproduced or clearly confirmed.
• Why it matters: This verifies a true cassette-related operating condition rather than a setup misunderstanding or unrelated alarm.

Remove the Cassette and Inspect the Feeding Set

• Stop the pump and remove the cassette.
• Inspect the cassette and tubing for improper seating, warped cassette housing, pinched tubing, kinks near the cassette, crushed tubing, stretched tubing, twisted tubing, debris, residue, or visible fluid contamination.
• Do not force a damaged or irregular cassette back into use.
• Expected outcome: The cassette and tubing appear physically normal and properly formed.
• Why it matters: Cassette Error can occur when the pump detects an unusual condition involving how the cassette or feeding set is operating.

Correct Any Obvious Cassette or Tubing Irregularities

• Straighten tubing and remove twists or kinks.
• Confirm the cassette is not visibly damaged, contaminated, warped, crushed, or improperly positioned.
• If the cassette or tubing appears damaged, replace the feeding set instead of reusing it.
• Expected outcome: Simple loading or tubing issues are corrected before retesting.

Reload the Cassette Properly

• Reload the cassette into the pump and confirm it is fully seated and aligned.
• Close the pump door or loading mechanism completely.
• Press Continue if prompted.
• Restart feeding using an appropriate test setup, not an active patient setup.
• Expected outcome: The pump accepts the cassette and resumes operation without the Cassette Error alarm.
• If this resolves the alarm, complete functional verification and return the pump to service.

Check for External Contamination or Moisture

• Inspect the cassette loading area for visible formula, water, residue, or debris.
• Clean and dry the external cassette area according to facility-approved cleaning practices.
• Do not use sharp objects to scrape sensor or cassette-loading areas.
• Expected outcome: The cassette area is clean, dry, and free of buildup.
• Why it matters: Feeding solution or residue can interfere with cassette seating or cassette detection.

Replace the Feeding Set

• If the Cassette Error returns after reloading, replace the feeding set with a new compatible Kangaroo OMNI feeding set.
• Prime and load the new set correctly before retesting.
• Expected outcome: A known-good feeding set operates without the Cassette Error alarm.
• Why it matters: This isolates whether the alarm is caused by the disposable cassette or feeding set rather than the pump.

Test Pump Operation With the New Set

• Run the pump long enough to determine whether the Cassette Error returns.
• Consider the programmed flow rate when evaluating recurrence because detection time may be longer at lower rates.
• If the pump runs normally with a new set, document the disposable set as the likely cause.
• Expected outcome: The pump runs normally without recurring Cassette Error.

Isolate Device-Related Failure

• If the Cassette Error continues after the cassette has been inspected, reloaded, and replaced, remove the pump from use.
• Use a different Kangaroo OMNI pump for patient feeding.
• Expected outcome: The issue follows the pump, not the feeding set.
• Why it matters: Persistent Cassette Error after replacing the set suggests a pump-side cassette detection, loading, sensor, or operating mechanism fault.

If the Problem Persists

If the Cassette Error continues after correcting cassette irregularities, cleaning visible external contamination, reloading the cassette, and replacing the feeding set, external and common disposable-set causes have been ruled out.

Remove the pump from service, label it Out of Service, and send it for repair or bench evaluation.

Persistent cassette alarms may indicate an internal cassette detection, sensor, door/loading, or operating mechanism issue. Knowing when to stop is proper troubleshooting.

Clinical Use Tip

Never troubleshoot on an active patient. Move the patient to a backup device first.

For a Cassette Error alarm, do not repeatedly reload or restart the same patient setup if feeding delivery is interrupted or uncertain. Use a known-good pump and evaluate the suspect pump separately.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Kangaroo OMNI feeding pump reported with Cassette Error alarm during feeding. Staff stated pump alarmed and feeding delivery was interrupted."

Cause

What was observed during troubleshooting.

Example:
"Cassette removed and inspected. Tubing/cassette irregularity suspected. Alarm cleared after cassette was reloaded and feeding set was replaced."

Resolution

What action was taken.

Example:
"Replaced feeding set, reloaded cassette, primed, and verified pump operation without recurring Cassette Error. Device returned to service."

Helpful Details to Include (If Known)

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

Final Thought

Cassette Error troubleshooting should begin with patient safety, then move through visible cassette condition, proper loading, contamination checks, and feeding set replacement. If the alarm continues after the disposable set is ruled out, the pump should be removed from service for repair evaluation. Clear documentation helps show whether the problem was corrected externally or requires deeper service.

That is successful troubleshooting.
