Steelco EW 2 2S - 3S
Steelco · Model EW 2 2S - 3S
• Compatible and tested with peracetic acid (cold disinfection) and glutaraldehyde (chemo-thermal) • User and instrument recognition through bar code reading system or RIFD (Radio Frequency Identification). • Leak test at the beginning of the cycle and continuous monitoring during all cycle phases with automatic cycle stop in case of anomaly. • Precise endoscope channel-check (up to 7 channels for each endoscope ) with two independent monitoring systems through pressure and flow measurement and data logging during the whole cycle. • Disinfection of all the water used in the process with a two stage high level water filtering (0,5 Μm and 0,1 Μm filters) for endotoxin removal. • Integrated sterile air filter for channel leak test, purging and drying. • Self thermal disinfection cycle at 90°C as required from the UNI EN ISO 15883-4 rule including endoscope basket and connections. • Data logging of all program data and instrument parameters, graphically visualized as a curve. • Complete documentation on integrated printer or to PC/hospital server with SteelcoData software. • Large color LCD touch screen display for easy machine operation and endoscope/operator database management
Key tips
- ·A failed leak test means the scope does not get reprocessed or used - send it for repair, full stop.
- ·A shortened reprocessing cycle is a real infection-control failure, not a minor deviation - follow AAMI ST91 exactly.
- ·Track light-source lamp-hours against the manufacturer's limit rather than running to failure.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Chemical dosing pump fault
HighSymptoms: Under/over-dosed disinfectant; cycle fails self-test.
Root cause: Worn peristaltic pump or clogged dosing line.
Channel connector / leak test fault
HighSymptoms: Cycle aborts on leak or connectivity test.
Root cause: Worn connector fitting or a blocked scope channel.
Water filtration / UV fault
MediumSymptoms: Failed rinse-water quality alarm.
Root cause: Saturated filter or UV lamp failure.
Door seal / interlock fault
LowSymptoms: Won't start cycle, door won't seal.
Root cause: Worn door gasket or interlock switch.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Leak testing before each reprocessing cycle
- ·Scope reprocessing per AAMI ST91
- ·Light source lamp-hour tracking
- ·Annual full PM
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Chemical dosing pump fault
- Confirm the presentation - typically under/over-dosed disinfectant; cycle fails self-test - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: worn peristaltic pump or clogged dosing line.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the chemical dosing pump per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
