Understanding the ZOLL AED Plus: Key Features to Keep in Mind

Before we get into troubleshooting, let’s highlight some unique features of the ZOLL AED Plus that make it a top choice:

Real CPR Help®: This feedback system guides you in real-time, helping maintain correct compression depth and rate during CPR.
One-Piece CPR-D-padz® Electrode: The pre-connected pad design reduces application errors and improves ease of use.

Common ZOLL AED Plus Issues and How to Solve Them

1. Battery-Related Issues

Problem: The device won’t power on or shows a “low battery” indicator.

Solution:

Check Battery Orientation: Ensure each battery is inserted in the correct orientation. The ZOLL AED Plus uses a 10-battery setup, and all batteries must be oriented properly.
Use Lithium Batteries: Always use ZOLL-approved lithium batteries for optimal performance and longevity.
Regular Replacement: ZOLL AEDs require battery replacement every 5 years, but periodic testing and monthly checks are advised.
Battery Test: Run a manual battery test to confirm the power source.

2. Pad Connectivity and Adhesion Issues

Problem: The device displays “Check Pads” or fails to detect proper pad placement.

Solution:

Check Connection Points: Ensure pads are securely connected to the device’s electrode input.
Clean Skin Before Application: Moisture, body hair, or dirt can prevent pads from adhering correctly. Dry the chest area and trim hair if necessary.
Replace Expired Pads: Check expiration dates on pads. Replace them immediately if they’re past their due date.

3. Error Messages and Shock Failure

Problem: AED displays unexpected error messages or fails to deliver a shock.

Solution:

Clear Skin Obstructions: Ensure nothing obstructs pad placement or contact with the skin, including moisture or jewellery.
Stand Clear Warning: When instructed to “Stand Clear,” ensure all bystanders are not touching the patient to avoid shock interference.
Self-Test Diagnostics: Perform a self-test as outlined in the AED’s manual to diagnose any underlying issue if shock fails repeatedly.

4. Self-Test Failures

Problem: The AED’s self-test does not pass, or a “Service Needed” light appears.

Solution:

Run Manual System Test: If the automated self-test fails, initiate a manual system test to identify specific errors.
Internal Inspection: Look for any obvious signs of wear or damage to internal components and wiring. Contact ZOLL support if damage is suspected.
Contact Technical Support: If the self-test continues to fail, it may indicate a need for professional servicing.

5. Speaker and Voice Prompt Issues

Problem: Voice prompts are unclear, distorted, or not functioning.

Solution:

Speaker Cleaning: Dust or dirt can accumulate, affecting sound quality. Clean the speaker grill with a soft brush.
Restart the AED: A simple reset may resolve sound issues.
Volume Check: Confirm that the volume setting is appropriately adjusted for clarity.
Professional Repair: Persistent sound issues may require authorised repair to replace faulty audio components.

6. Temperature and Environmental Exposure

Problem: The AED has been exposed to extreme temperatures or environmental conditions.

Solution:

Store in a Controlled Environment: Keep the AED in a dry, temperature-controlled area between 0°C and 50°C.
Cool the Device if Overheated: Allow it to cool before conducting a function test if it feels hot.
Inspect for Environmental Damage: Look for signs of temperature-related damage, such as battery swelling or component warping, and arrange for service if damage is found.

7. Electrode Pad Drying or Gel Buildup

Problem: Pads are dry or show gel buildup, affecting adherence.

Solution:

Replace Pads Immediately: Gel buildup or dryness indicates the pads are no longer viable and must be replaced.
Store Pads Properly: Ensure pads are stored in their sealed packaging until needed to prevent drying out.

8. Display Screen Issues

Problem: The screen is unresponsive or showing distorted visuals.

Solution:

Reset the AED: A reset can often resolve display issues.
Check for Screen Damage: If the screen is physically damaged, contact technical support for screen repair or replacement.
Run System Check: Perform a manual system check to ensure the device’s operational integrity.

9. Device Overheating During Extended Use

Problem: The AED feels warm after continuous use or testing.

Solution:

Allow for Cool-Down: After extended use or testing, let the AED cool naturally.
Limit Repeated Testing: Excessive testing or continuous usage without breaks can lead to overheating.

10. AED Won’t Charge Properly or Keeps Powering Off

Problem: The device keeps powering off unexpectedly or fails to maintain charge.

Solution:

Battery Check: Ensure all batteries are within expiration and seated securely.
Verify Battery Contacts: Clean any debris from battery contacts that might interrupt power flow.
Seek Professional Service: Persistent power-off issues may indicate an internal power component malfunction that requires repair.

11. LED Indicator Malfunction

Problem: Status LEDs are not functioning or show incorrect colours.

Solution:

Test LED Response: Run a system test to reset the LED indicators.
Check Manual for LED Status: Reference the AED’s manual for the meaning of LED signals. In some cases, lights may indicate service needs.
Service Required: If LED problems persist, the AED may need servicing.

12. Shock Button Malfunction

Problem: The shock button does not respond or seems jammed.

Solution:

Test the Button in Self-Test Mode: Activate self-test mode to assess if the button issue is internal or a user error.
Clear Obstructions: Ensure nothing obstructs the shock button or surrounding areas.
Contact ZOLL for Repair: If the button remains unresponsive, professional service is necessary to resolve the issue.

13. Physical Damage or Wear

Problem: Cracks, dents, or visible wear on the AED casing or accessories.

Solution:

Inspect for Functional Integrity: Superficial damage might not affect functionality, but any damage should be monitored.
Replace Damaged Parts: Order new parts if damage affects battery covers, pad connections, or buttons.
Professional Assessment: If structural damage is extensive, a full assessment by ZOLL is recommended.

14. Memory or Data Retrieval Issues

Problem: Unable to retrieve or download data logs after use.

Solution:

Use ZOLL-Compatible Software: Ensure you are using the correct ZOLL software for data retrieval.
Check Cable Connections: Verify that the AED’s data ports and connecting cables are properly secured.
Contact Technical Support: Persistent issues with data access may require technical assistance.

15. Service Required Light Remains On

Problem: The “Service Required” light is continuously illuminated.

Solution:

System Reset: A reset may temporarily clear the service light.
Run Full Diagnostic: Conduct a thorough diagnostic check to identify specific issues triggering the light.
Schedule Maintenance: If the service light remains on, professional servicing is required to ensure full operational integrity.
