Troubleshooting the System
Problem Probable Cause and Solutions
Insufficient wash solution is
flowing through the sample
port
1. Check the level of wash reagent and install a new
bottle of Bayer Diagnostics wash reagent if
required.
2. Ensure that the bottle of wash reagent is seated
correctly on the reagent manifold.
3. Check the wash reagent fitting for obstructions.
4. Check the sample port for obstructions or leaks and
ensure that it is installed correctly.
5. Inspect the capillary seal and O-rings for proper
installation and for deterioration. Reinstall or
replace them if required.
6. Check the sample tubing for obstructions or leaks.
7. Check the sample pump tubing for worn areas or
leaks at the fittings.
8. Test the reagent pump flow rate as described in
Pump Functions Test, page 4-58, and verify that the
pump is operating correctly.
9. Clean the roller cage and shaft and replace the
pump tubing if required.
No waste is flowing out of
the waste outlets into the
waste bottle
1. Check for obstructions in the sample entry
components as described in Removing Obstructions
from the Sample Entry Components, page 4-79.
2. Check for obstructions in the measurement module
as described in Removing Obstructions from the
Measurement Module, page 4-82.
3. Check for obstructions in the CO-ox module as
described in Removing Obstructions from the
CO-ox Sample Path, page 4-87.
4. Check for obstructions in the measurement tubing
and waste outlets.
5. Ensure that the sample port, retainer ring, and
O-rings are installed correctly and not leaking.
6. Inspect the sample pump and waste pump tubing
for obstructions and leaks, and inspect the roller
cages and shafts.
7. Test the sample pump and waste pump flow rates as
described in Pump Functions Test, page 4-58, and
verify that the pumps are operating correctly.
