1. What does it mean when an error message appears mid-cycle?
It could be something as simple as a loose lid latch or as complex as a valve failure. When in doubt, pause and check the error message—don't just assume it's nothing.

Medivators AER Alarms and Errors Guide
Understanding Medivators Alarms and Errors: A Practical Guide for Operators and Techs
Keeping an endoscope reprocessor like the Medivators Advantage Plus™ running smoothly is critical to infection prevention and patient safety. When an error message flashes across the screen, operators need to understand what's happening—and fast.
This guide walks through common alarms and errors for Medivators AERs, what they typically mean, and where to begin with troubleshooting. Whether you're a daily user or the in-house maintenance lead, having a working understanding of these alerts can keep things moving and reduce unnecessary downtime.
We'll also touch on specific alerts like No Fluid Flow Error, No Air Flow Error, and Basin Sensor Error—plus how different models like the DSD-201 and DSD EDGE might vary.
Medivators Advantage Plus Systems
The Medivators Advantage Plus™ Automated Endoscope Reprocessors (AER) is a workhorse in facilities where high-level disinfection is performed daily. These units are built to process multiple endoscope channels using automated cycles to improve consistency and reduce human error.
Each Medivators automated endoscope reprocessor monitors critical disinfection steps, including chemical concentration, temperature, fluid flow, and channel connectivity. When something isn't right, the machine will trigger an alarm or show an error message to prevent incomplete reprocessing. This kind of monitoring puts them among the most advanced scope washer systems available.
Why Error Messages Matter
Alarms and errors are more than simple alerts—they're the system's way of flagging something that needs attention. These messages can stop a disinfection cycle in its tracks if there's an issue that might compromise safety.
Here are just a few issues they help prevent:
- Disinfectant failing to reach all endoscope channels
- Fluid blockages that disrupt flow
- Mechanical issues like a seized spray arm or leaking valve
These alerts help keep patients safe, protect your equipment, and catch problems before they lead to costly repairs. When a system error occurs and stops a cycle, that pause could be the one thing preventing a contaminated scope from being reused.
Some error patterns—like Low Dis Res, Hi Dis Res, or Low CBR—may also point to problems in the disinfectant flow or chemical monitoring system.
Common Endoscope Reprocessor (AER) Alarms and Errors
AER alarms and errors often appear as an error message or code on screen. The system error may be linked to a specific component, a user misstep, or a deeper internal problem. Medivators Advantage Plus automated endoscope reprocessors track and report many types of events—some mechanical, some operator-related.
1. Spray Arm Issues
If the spray arm gets stuck or disconnected, it can't do its job of cleaning out the endoscope channels. That often leads to a stop in the cycle.
- Look for cracked O-rings or anything blocking movement.
- Make sure the arm turns freely when you start the machine.
Problems with pressure? A faulty air compressor or a leak somewhere in the tubing might be to blame.
- Listen for sputtering or gaps in airflow.
- Double-check tubing and the lid for secure fits.
3. Chemical Delivery Fault
If the disinfectant isn't getting where it should—because of low reservoir levels or blockage—you'll get an alert.
- Refill your disinfectant and inspect all filter components.
- If unsure, consult the service manual to check concentration levels of peracetic acid.
4. Sensor or Circuit Board Malfunction
Sometimes the problem is inside the machine. If you've got random or recurring errors that don't match what you see physically, a sensor or circuit board may be acting up.
- Pull the error reports and check for a pattern.
- Determine whether the fault is persistent or intermittent.
A failed basin sensor will typically throw a Basin Sensor Error, which may prevent cycle start altogether.
5. Lid Not Secure
Even a small gap in the lid seal can cause the system to stop.5. Lid Not Secure
- Confirm the latch is locked all the way.
- Look for worn gaskets or obstructions around the lid.
Human error is common—and easy to fix. These include:
- Placing the endoscope incorrectly
- Skipping the insertion tube connection
- Leaving valves unsealed
How to Respond When a System Error Occurs
If you see an error pop up, don't panic. Here's a quick go-to checklist to follow:
- Read the Onscreen Error Message—Make note of the exact wording and any code provided.
- Check Past Event Logs—This tells you if it's a one-off issue or something recurring.
- Inspect Parts—Look over the spray arms, valves, tubing, filters, and any visible O-rings.
- Verify Scope Setup—Confirm that all connections are tight and in the right place, including the right-side channel adapters.
- Look It Up—Use the service manual to match the error message to possible causes.
- Restart (If Safe)—Only do this after confirming that the issue was minor and has been resolved.
Knowing When to Call for Service and Why Third-Party Service Matters
Some issues can be addressed internally, especially when the error occurs after a missed connection or minor fault. But if the same error message shows up repeatedly, or disinfection can't be verified, service is necessary, and MedService Repair can help.
A certified tech can:- Replace defective valves, sensors, or circuit boards
- Recalibrate the plus automated endoscope reprocessor
- Test cycle function using manufacturer-approved standards
- Access to compatible replacement parts, including o-rings, filters, and valves
- A way to maintain uptime while keeping costs down
- Support interpreting error messages and resolving alarms quickly
And we can't stress enough that whether you're dealing with Advantage Plus, DSD EDGE, or DSD-201 AER service, always document what occurred, what actions were taken, and the time and date. This may help a certified technician get to the bottom of the issue more quickly.
The Role of Service Manuals and Documentation
Your service manual is one of the most valuable resources for troubleshooting Medivators Advantage Plus systems. It includes:
- Diagrams and part breakdowns for Medivators Advantage Plus Automated units
- Detailed steps for manual cleaning and error recovery
- Specs on filters, o-rings, lid gaskets, and other parts
- Acceptable peracetic acid concentration levels for high-level disinfection
Maintenance Tips to Minimize Errors
Routine checks help avoid service calls and reduce the number of error messages you'll encounter.
- Daily: Wipe screens, inspect the spray arm, and check the lid and O-rings.
- Weekly: Review filters, tubing, and reservoir levels.
- Monthly: Confirm system pressure and inspect insertion tube connectors.
- As Needed: Replace worn valves, clean out debris, and confirm acceptable performance.
Final Thought
When an error occurs, it's easy to think the machine is failing. But in reality, the system is doing its job—flagging issues before they result in improper high-level disinfection or patient risk.
The Medivators Advantage Plus is a highly monitored system. Alarms, reports, and service documentation help operators correct problems early and keep reprocessing procedures on track.
