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.
Aperture / flow-cell blockage or partial obstruction
HighSymptoms: Flagged or implausible CBC counts, voteouts, clog alarms, poor precision.
Root cause: Debris or a clot partially blocking a counting aperture or the flow cell.
Sample probe / piercer / valve wear
MediumSymptoms: Short samples, aspiration errors, cap-piercing failures, carryover.
Root cause: Worn or bent sample probe / closed-vial piercer, or a worn shear / segment valve.
Reagent / lyse delivery fault
MediumSymptoms: WBC, HGB or diff results shifted, high background, reagent alarms.
Root cause: Reagent depleted or wrong lot, or a pinch-valve / tubing fault.
Optics / laser fault (diff)
MediumSymptoms: Diff scattergrams abnormal, missing populations, flow-cell or laser alarm.
Root cause: Contaminated or aged flow cell, or the laser / optics.
Vacuum / pressure out of range
MediumSymptoms: Multiple parameter errors, priming failures.
Root cause: Pump or regulator drift.

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: Clog alarm or flagged counts
- Run the instrument's aperture / flow-cell clear and flush cycles.
- Run a background count and confirm it is within limits.
- Run controls at all levels.
- Clean or replace the aperture bath / flow cell if clogs recur.
- Confirm precision on a replicate sample before releasing results.
Symptom: Short samples or aspiration errors
- Inspect the sample probe / piercer for wear or a bend.
- Check the shear / segment valve and tubing for leaks or wear.
- Verify vacuum and pressure against the service spec.
- Replace the probe / piercer, valve or tubing as found.
- Re-run controls.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Beckman Coulter has become aware of an intermittent issue in which the optional flag Previous Sample Had Sperm was enabled but not displayed so that a carryover event could have been investigated.
- RECALL
The Strip Provider Modules (SPM) on some of the instruments had not been inspected during manufacture for correct seal placement and integrity.
- RECALL
Beckman Coulter has determined that there is a potential for under-reporting casts. This can occur if per high-power field (/HPF) units of measurement for casts are selected in the iQ200 software, but the abnormal threshold and/or grading format is set up based on reporting per low-power field (/LPF)* or *per microliter. This may occur during initial method validation or if settings are altered after the initial validation.
- RECALL
A subset of Lot 7212154 A of the iChem VELOCITY Urine Chemistry strips has an incorrect pad placed in the location of the leukocytes pad. This will result in control CB failure for leukocytes and may generate false negative erroneous results for leukocytes.
- RECALL
iQ200 Series Urine Microscopy Analyzer may intermittently fail to read urine sample dilution barcode labels causing erroneous results that could delay treatment for health conditions such as hematuria.
- RECALL
Unpaired lots of AU lyophilized chemistry calibrator level 1 and 2 have been distributed. Calibrator level 1 and 2 must be paired when used for calibration and cannot be used in any other combination. If lot numbers are not correctly paired, calibration can be run using incorrect set points which may generate erroneous results. QC failures could occur if incorrect pairs of calibrators are used.
- RECALL
Beckman Coulter initiated a design change to update the Automate PC image to accommodate the operating system change to Windows 10.
- RECALL
Beckman coulter has received complaints regarding leaking and cracked C cups. When the cup cracks, coolant can leak onto the connectors of the Printed Circuit Boards (PCB) in the analyzer, resulting in a short-circuit causing the instrument to go into a stop mode.
- RECALL
Beckman Coulter is recalling the LH 750 and LH780 Hematology Systems because the use of the diluent lots may eventually result in a compromised Hgb cuvette.
- RECALL
The recall was initiated because Beckman Coulter has confirmed customer reports of secondary tubes being labeled with two different barcode labels on the AutoMate 2500 Family (previously referred to as OLA2500 Systems) units which can cause misidentification of a sample when software versions lower than version 4.1 is used.
- RECALL
The recall was initiated because Beckman has identified a problem with Integrated Circuit chips used in different boards throughout the analyzer.
- RECALL
The recall was initiated because Beckman Coulter has identified a problem with Integrated Circuit Chips used in different boards throughout the Beckman Coulter LH500/HmX/HmX Autoloader Hematology analyzer.
- RECALL
The recall was initiated after Beckman Coulter identified four (4) issues with the COULTER LH 500 Series System and the Unicel DxH 800 Coulter Cellular Analysis System: Issue 1: There is a potential for misidentification to occur when the system is configured in languages other than English or Chinese. The characters #,@,[,\,],`,{,|,}, or ~ are substituted or omitted in other languages. The issu
- RECALL
Issue 1: The system will substitute or omit the characters # @ [\] ' {I) when the system is configured in a language other than English or Chinese. Example: Using the character @, a substitution in the string '123@456' would result in '123#456' and an omission would result in '123456' Issue 2: The system will omit the character ~ regardless of language. Impact: There is a potential for Specimen
- RECALL
Beckman Coulter has become aware of a potential issue in which the Sample ID information embedded in the barcode affixed to a slide made by the Coulter GEN*S and LH SlideMaker does not match the text.
- RECALL
There is a potential for erroneous yet credible results for Body Fluids on the LH700 series hematology analyzers when a cassette label fails to read and the subsequent sample is cycled in Body Fluid mode.
- RECALL
There is a risk of sample misidentification when processing samples in the Manual aspiration mode.
- RECALL
Risk of injury to workers due to mechanical or electrical hazards.
- RECALL
Biohazard situation exists for users.
- RECALL
Incorrect Hemoglobin result can be reported with software version 2A and higher.
- RECALL
Device design allows for cross contamination issue to occur, possibly affecting assays and results reports.
- RECALL
Software vote out logic changed. Erroneous white blood cell counts.
