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.

Error Codes

Extracted directly from this unit's own service manual.

INSUFFICIENT SAMPLEThe safety switch of the sample needle is activated (sample cup empty). Liquid detection of the sample needle is not detecting any liquid after aspirating the sample (detection of air bubbles). Error message Cause Action Error message Cause Action E02 SYSTEM EMERGENCY HALT Sample or reagent arm, for example, were accidentally touched during measurement. The analyzer immediately interrupts all operations. Eliminate the error if possible and select SHIFT+F6 RESET SYSTEM. The analyzer then asks you on the screen, whether the interrupted measurements, the results of which were cancelled, shoul

E05 NO CLEAN CUVETTEIf no clean cuvette is available on the cuvette rotor, (e.g. caused by a vacuum error), the wash arm with the dry block does not move down to the bottom of the cuvette to prevent contamination of the dry block. Thus no clean cuvette is available in the analyzer. Eliminate the error if possible (for example, clean and dry the rotor manually, install a new one or refill it) and select SHIFT+F6 RESET SYSTEM. If the error occurs again, inform the Technical Support. E07 SYSTEM RESET INCOMPLETE Due to further errors the system reset was incomplete. Eliminate the error if possible and select SHIFT+F6

E10 NO VACUUMVacuum pump defective. Vacuum tubing defect or clamped. Vacuum sensor defective or not well adjusted.The vacuum is not sufficient for a period longer than 2.5 seconds. Select F1 CHECK AGAIN and inform the service personnel. Check that the tubing that connects the analyzer with the pump unit or the analyzer with the bottles is not kinked or clogged. Service personnel only: Check if the vacuum pump is working properly and replace the membrane or the complete vacuum pump, if necessary. Check the vacuum tubing for leakage. Check the vacuum sensor and re-adjust it, if necessary.

E11 WASTE FULLThe WASTE FULL signal is "high" for 1 second (or longer). Empty the waste container. Check if the waste container floating switch is working properly and replace/repair it, if necessary. Check the wiring. Service personnel only: Check if the waste full signal detection signal is present on the system board. When the signal is present, malfunctioning of the system board may cause the problem. E12 RUNNING OUT OF WATER The upper level detector detects "No water" in the water container, although the pump is switched on for a period longer than 25 seconds. Check if there is enough system liquid in

E13 LAMP FAILUREA counter over range signal is detected during a measurement. The signal counter over range signal is generated when the photocell signal is too low. When the blank data values are incorrect too, the gain setting of an input amplifier is wrong or an input amplifier is defective (on the photometer board). Select F1 CHECK AGAIN. If the error occurs again, check if the lamp is working and replace it, if necessary. Inform the Technical Support. Service personnel only: Check if the lamp voltage is present and well adjusted. Adjust or repair the voltage supply, if necessary. Check if the selected fi

Inform the Technical Support if the error occurs again. E16 CONCENTRATED WASTE FULL (only if the optional container is installed) Empty the optional concentrated waste container. Check if the concentrated waste container floating switch is working properly. Check the wiring.

E17 INSUFFICIENT WATERThe lower level detector detects "No water" in the water container. Check if there is enough system liquid in the container and refill if necessary. Check if the liquid tubing is leaking or if it is blocked and repair if necessary. Check if the filter in the container is blocked and replace if necessary. Service personnel only: Check if the system liquid level detection circuit is working correctly and repair if necessary. E20 SAMPLE SYR. POS.

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.
