Beckman Coulter AU5800
Beckman Coulter · Model AU5800
Reliability - Establishes high reliability targets comparable to the industry-leading AU analyzers. Standardization – Standardized to the current AU480 and AU680 analyzers: same results, same sample racks, same reagents, same calibrators and same software. Broad menu – Offers an expansive menu of general chemistry, esoteric, therapeutic drug monitoring, drug of abuse, urine chemistries, special protein and serology assays. Best-In-Class Ion Selective Electrodes (ISE) – Incorporates the same high-performance ISEs with proven reliability and performance demonstrated in all AU analyzers.
Key tips
- ·Run QC controls before trusting any repair - an analyzer that passes self-test can still report clinically wrong results.
- ·Rule out a reagent lot change before opening the instrument - it can look exactly like a hardware fault.
- ·Centrifuge rotors have a hard retirement age/cycle limit regardless of visible condition - don't eyeball it.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Assay / QC failure across a channel or the whole system
HighSymptoms: Controls out of range, calibration fails, flagged results, drift over a shift.
Root cause: Reagent or cuvette issue, lamp ageing, a probe / mixer / wash-station fault, or ISE-module problems.
Sample / reagent probe clog or crash
MediumSymptoms: Short aspiration, no dispense, clot detection, probe-position error.
Root cause: Clogged or bent probe, or a clot in the sample.
Cuvette / reaction-rotor fault
MediumSymptoms: High cuvette blanks, non-uniform results by position, rotor-drive error.
Root cause: Worn / scratched cuvettes or a wash fault, or a rotor-drive fault.
ISE module fault (Na / K / Cl)
MediumSymptoms: Electrolyte results biased or noisy, ISE calibration fails.
Root cause: Aged ISE electrodes / reference, or a pinch-valve / tubing fault.
Water / vacuum / pressure system fault
MediumSymptoms: Multiple station alarms, priming failures, poor wash.
Root cause: Water / DI supply quality, a pump, or a vacuum / pressure regulator.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC controls run and reviewed
- ·Calibration verification per assay
- ·Routine cleaning and decontamination
- ·Scheduled reagent-path and pump-tubing maintenance
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Assay or QC failure
- Run fresh controls at all levels.
- Confirm reagents are in date, correctly loaded and mixed.
- Run the photometer check and replace the lamp if energy is low.
- Clean the probes, mixers and wash stations.
- Recalibrate the affected assay / ISE module and re-run QC.
Symptom: Probe clog or crash
- Inspect the probe for a bend or blockage and clear it.
- Run the fluidics prime / wash cycle.
- Check for a clot in the sample.
- Verify liquid-level sensing and probe positioning.
- Replace the probe if aspiration is still short.

Documents & Manuals
Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Beckman Coulter is recalling the Rack ID Labels because the Rack ID number displayed and the Rack ID barcode label do not match.
- RECALL
The recall was initiated because Beckman Coulter has identified a software error on AU5800 analyzers with the Automation Ready (AR) Sampler Kit. This software error results in the failure of the concentrated wash solution pump to stop, creating an overflow or leak on each analyzer unit.
- RECALL
Beckman Coulter, Inc. initiated this recall because there is a software error that has the potential to cause the reporting of erroneous patient results because of misidentification by the AU5800 system.
- RECALL
Due to a software data storage limitation which only occurs under certain conditions, measurements of the Reagent Blank (RB) or Calibration (CAL) sample results are not saved and the software reverts to a previously stored, acceptable RB/CAL result.
- RECALL
Beckman Coulter is recalling the AU8500 Clinical Chemistry Analyzer because there is no labeling on the diluted detergent tank to show the proper disposition of the on/off valve.
