7. Troubleshooting
7.3 Typical ll or drain problems
Fill and drain problems may be due to several causes:
1stThereisinsucientreagent
 • Verify that the ll level in the system bottles, RTU-bottles and paran containers is
sucient.
2. Insucientpressureorvacuum
The instrument is unable to create sucient vacuum (for a ll) or pressure (for a drain) in the
retort.
 • Check whether the system bottles and RTU-bottles concerned have been inserted
correctly.
 • Verifythatallsystembottlesarefullypushedhomeintotheirsockets.
 • Checkwhetherdirtdepositshavecollectedundertheretortseal.
3. There is a blockage in the air or reagent lines
Blockages in the reagent lines are typically caused by paraffin or tissue debris. If it is not
possible to drain the reagent in the retort, try to remove the blockage as follows:
 • Heattheretorttothemaximumpossibletemperature(consistentwiththereagentcur-
rently in the retort, if any). Leave the retort at this temperature for at least 15 minutes.
 • Whentheretortreachesmaximumtemperature,attempttocarryoutallinganddrain-
ing cycle.
 • Ifthereisnoreagentintheretort:
Clean the retort in a cleaning program (see Chapter 6.1).
If you cannot determine or eliminate the problem by carrying out the above
listed steps, call Leica Technical Service before attempting to run any further
programs.
