Roche OMNI C
Roche · Model OMNI C
Delivers key results from small footprint Helps you decrease your costs and spend more time with your patients Captures and reports patient and QC data automatically Menu: BG, ISE, tHb, SO2.
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.

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: QC / calibration failure across a channel or the whole system
- Run fresh controls at all levels and note which analytes fail.
- Confirm reagents are in date, correctly loaded, mixed and not bubbled.
- Run the photometer / lamp-energy check and replace the lamp if energy is low.
- Clean the sample and reagent probes, the mixers and the wash / cuvette-wash stations.
- Recalibrate the affected assay / ISE module and re-run QC.
Symptom: Sample or reagent probe clog / crash / short aspiration
- Inspect the probe for a bend or blockage and clear it (wire / sonicate per the manual).
- Run the fluidics prime and the probe-wash cycle.
- Check for a clot or fibrin in the sample and the liquid-level sensing.
- Verify probe positioning / alignment.
- Replace the probe if aspiration is still short.
Symptom: ISE electrolyte results biased or noisy / ISE calibration fails
- Run the ISE calibration and check the slope / drift against spec.
- Replace an ISE electrode or the reference that is at end of life.
- Check the ISE pinch valves and tubing for wear or air.
- Confirm the ISE standard packs are in date.
- Re-run ISE QC before releasing electrolyte results.
Symptom: High cuvette blanks / position-dependent results
- Run the cuvette blank / photometric check.
- Clean or replace worn / scratched cuvettes or the reaction segment.
- Check the cuvette-wash station nozzles and drying.
- Confirm the water / DI supply quality.
- Recalibrate and re-run QC.

- RECALL
Potential for hemoglobin derivatives which are outside of the quality control (QC) limits to not engage the auto lock out feature of the system for 02Hb, COHb, HHb, MetHb or SO2.
- RECALL
The firm is withdrawing claims that pleural, pericardial, ascitic and cerebrospinal fluids are appropriate sample types for use on these instruments.
- RECALL
If the sample volume is insufficient, the analyzer may issue erroneous results without any indication to the user that the problem is insufficient sample volume.
- RECALL
Air bubbles trapped in the PO2 electrode will cause falsely elevated patient test results.
