Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Reagent / paraffin transfer or handling fault
HighSymptoms: Stations not filling or draining, retort not filling (processor), transport arm mis-places baskets, error alarm halts the run.
Root cause: Worn pump / valve, a blocked line, a level-sensor fault, or a transport-drive / gripper fault.
Retort / chamber pressure or vacuum fault (processor)
MediumSymptoms: Pressure / vacuum not achieved, poor infiltration, seal alarm.
Root cause: Worn retort door seal, a vacuum / pressure-pump fault, or a valve.
Poor or inconsistent staining
MediumSymptoms: Slides over- / under-stained, uneven, station-time drift.
Root cause: Exhausted reagents, wrong programme, incorrect agitation, or a timing / arm fault.
Heater / paraffin-bath / oven fault
MediumSymptoms: Paraffin not molten or too hot, oven not at temperature, bath alarm.
Root cause: Heater or temperature-sensor fault.
Fume-extraction / carbon-filter fault
LowSymptoms: Reagent fumes in the room, filter-change overdue.
Root cause: Saturated carbon filter or a fan fault.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Error alarm halts a run
- Note the alarm / error code and check the history log.
- Confirm reagent, paraffin and water levels and correct vessel placement.
- Check the affected station / retort fills and drains fully.
- Inspect seals and the transport arm.
- Follow the service manual for the specific alarm; replace the pump, valve or seal as isolated.
Symptom: Poor or inconsistent staining / processing
- Confirm the correct programme and station times.
- Fit fresh reagents and confirm fill levels.
- Check agitation / dwell and the water supply where used.
- Run a control slide / block and compare to a reference.
- Escalate a timing or transport-arm fault to the OEM.
