Troubleshooting
Occasionally small faults may cause major problems. This chapter may help to solve the most common faults
and explain why a specific problem occurs.
A lot of the problems or errors are due to a lack of maintenance. Remember that this instrument operates
with a considerable amount of whole blood, virtually undiluted, stores it in a pipette for one hour and then
cleans pipettes for re-use. Therefore, it is important to keep to the maintenance schedules. It is
recommended that trained service personnel checks and applies service to the instrument at least once a
year. Errors which are not explained in this section can usually not be solved by the operator. Refer to the
Service manual for more information (available only in English).
The error numbers are displayed in the PC software.
11.1 - General error procedure
Whenever an error occurs, follow the instructions given in the error message on screen. If no instructions
are given, follow this general procedure:
1. Clear the error by pressing button
Clear error
.
When the error is not cleared or the error occurs again and cannot be solved:
1. Close the Interrliner PC software.
2. Reset the internal power unit (switch is located at the bottom of the internal power supply).
3. Start the Interrliner PC software.
If the error still occurs and cannot be solved, switch OFF the instrument and call for service.
11.2 - Flushing liquids
After each sample aspiration the entire system is washed automatically.
If there is no liquid flow:
▪ Check that the peristaltic pumps are running. If the pump tubes are worn or leaking, replace the tubes.
▪ Check that the pump tubes are installed correctly.
▪ Check the tubes between the containers and pumps/valves.
▪ Unscrew the cap from the container. Check the pick-up tubes in the container and that there is enough
liquid in the container.
▪ Check the tubes for blockages or kinks.
11.3 - Reagents
Check the expiry dates of the reagents regularly. Do not use the reagents if expired.
Note: If expired reagent has been used accidentally, the results obtained with these reagents may only
be used, when the expiry date was not exceeded more than 30 days.
Diluent
is sensitive for bacterial growth. The solution should be discarded if it becomes turbid or infected.
