Insufficient Fluid Flow
Use this table if you observe problems with fluids flowing too slowly, erratically,
or not at all.
Problem Probable Cause and Solutions
Insufficient wash solution is
flowing to clean the sample
path
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 reagent fitting for obstructions.
4. Install a new bottle of Bayer Diagnostics wash
reagent.
5. Inspect the sample path in the measurement module
for obstructions and leaks.
6. Verify that all sensor O-rings and sensors are
correctly aligned with the sample path and that the
O-rings are not deteriorated.
NOTE: The reference sensor has two O-rings.
7. Inspect all tubing and fittings for leaks.
8. Check the waste outlets for obstructions.
9. Verify that the wash, foam, and diverter valves are
operating correctly as described in Valves Test, page
4-62.
10. Test the reagent pump flow rate as described in
Pump Functions Test, page 4-58, and verify that the
pump is operating correctly.
11. Clean the roller cage and shaft and replace the
pump tubing if required.
