Description Causes Solutions/Comments Result Interpretation
The analyzer has detected an
initial air leak in the vacuum
system. This condition is
detected only at the
beginning of a test.
• Possible vacuum leak in the
analyzer or a malfunctioning trigger
solenoid pump
• No sample in PFA test cartridge
• Air entrapped in PFA test cartridge
when sample was loaded
• Defective PFA test cartridge
• Verify that sample was added to PFA test
cartridge. Rerun the test with appropriate
sample volume (800µL). Perform a Self Test
via the Maintenance menu without the
cleaning pad to test the vacuum system. If
the vacuum test passes, a malfunctioning
solenoid pump may be the cause for the air
leak. Contact Siemens Service for solenoid
pump troubleshooting procedure. If the
vacuum test fails, perform Manual O-Ring
Maintenance Procedure via the
Maintenance menu. Clean or replace O-
Ring as per maintenance instructions.
Perform self test. If vacuum leak test passes,
rerun sample. If problem persists, contact
Siemens Service.
• Prime system from Maintenance menu.
• Rerun the test with a new PFA test cartridge
and sample.
