Sterilization Device
Technical Service & Fault Diagnosis
We provide technical service, fault diagnosis, maintenance and modernization for H₂O₂ and steam sterilizers and washer-disinfector systems.
When a sterilization system fails or experiences performance loss, the real question is not which part failed — but why the problem occurred.
Encosoft does not approach technical service purely from a maintenance and repair perspective. We analyze system behavior with manufacturer-level knowledge, identify root causes and develop solutions that prevent recurrence.
Our goal is not just to get the device running again — it is to preserve its reliability, performance and long-term sustainability.
Root Cause, Not Parts
We investigate the source of the problem, not just the symptoms. We identify why the fault occurred to deliver lasting solutions.
Every Intervention Documented
Our service reports comprehensively record procedures performed, measurements taken and technical findings.
Manufacturer-Independent
We work across brands and select the technically correct solution.
Systems We Service
H₂O₂ Sterilizers
Fault diagnosis, maintenance, repair and technical support for low-temperature hydrogen peroxide sterilization systems.
Steam Sterilizers
Technical assessment and service of control, vacuum, steam, pneumatic and measurement systems in hospital-grade steam sterilizers.
Washer-Disinfector Systems
Technical service of control, washing, dosing, temperature and related mechanical systems in washer-disinfector units.
CSSD Technical Support
We provide technical service and engineering support for sterilization and washer-disinfector devices used within hospital Central Sterile Services Departments (CSSD).
Technical Engineering Support
in Four Modes
We adapt our service delivery to the urgency, geography and complexity of each situation.
Field Service
We deploy to hospitals, biomedical departments and sterilization centers for on-site fault resolution, PM programs and commissioning support. Field presence means direct access to system hardware, real-time instrumentation and faster resolution of complex faults.
- Fault diagnosis with calibrated test equipment
- Component replacement and circuit-level repair
- Cycle parameter verification and adjustment
- Safety system audit and compliance check
- Post-repair commissioning and recommissioning
- Technician handover report and service documentation
Remote Technical Support
Remote support is not a stopgap — for many fault types it is the fastest resolution path. Our engineers provide guided troubleshooting via video, remote PLC access where infrastructure allows, and structured fault analysis through system logs and error code interpretation.
- Error code interpretation and root cause guidance
- Software parameter review and adjustment support
- Guided component testing via local biomedical team
- Remote PLC monitoring (where connectivity allows)
- Documented step-by-step repair instructions
- Post-repair verification by local team
Emergency Support
When a sterilizer fails in a clinical setting, resolution time is critical. Encosoft provides priority response for urgent fault situations — first technical contact typically within hours, not business days.
- Priority queue for urgent clinical faults
- Same-day remote consultation
- Rapid parts identification and express shipping
- Escalation to field deployment when required
- Coordination with hospital biomedical teams
Preventive Maintenance
Preventive maintenance for sterilization systems reduces unplanned downtime and extends service intervals. Our PM protocols are built around OEM specifications combined with field-sourced insights on actual wear patterns and failure-prone components.
- System-specific PM checklists and intervals
- Wear-item replacement (seals, filters, sensors)
- Vacuum system performance testing
- Sterilant delivery system inspection and calibration
- Electrical connections and safety relay verification
- PM completion report with next service schedule

We Measure Before We Replace
We evaluate sensors, electronic components and field elements that are suspected to be faulty according to their operating principles. We check input and output values with appropriate measurement instruments and compare the results with the system's expected operating values.
We Examine the Symptom
We evaluate the error code, operator report and operating behavior of the device together.
We Review the Technical Data
We examine service documents, electrical diagrams, technical specifications and historical service records.
We Take Measurements
We check the electrical or physical values of the relevant component using appropriate measurement instruments, according to its operating principle.
We Compare Results
We compare measured values against expected operating values and information from other components of the system.
We Identify the Fault
The decision to replace a part or carry out technical intervention is made based on measurement and assessment results.
Control According to Operating Principle
Not every component is checked using the same method. We determine the value to be measured and the control method based on the operating principle of the sensor or component.
Voltage
Checking supply and output signals.
Current
Evaluation of current-based sensor and control signals.
Resistance
Checking resistive sensors, coils and related circuit elements.
Temperature
Comparing temperature sensor readings with system values.
Pressure
Checking pressure sensors and process values.
Technology
Faster Access to Technical Knowledge
We make service documents, device information and historical technical data more quickly accessible using AI-assisted tools. We use these tools to support access to the technical knowledge needed in fault diagnosis and to support the assessment process.
Physical measurement and technical decisions are made by the engineer.
Fault Diagnosis Backed
by Technical Knowledge
Our engineers' field experience is backed by a structured knowledge base and historical service records. Failure patterns previously identified for the same platform and device type accelerate the diagnostic process.
Cumulative Fault Data
Every service task is recorded. Fault data accumulated over time enables faster root-cause identification for similar symptom presentations.
Platform-Specific Knowledge Base
Fault modes, circuit behaviors and intervention protocols specific to Stericool, Trans and other systems we service are held in structured form.
Remote-Supported Diagnostics
System logs, error codes and video-guided instructions enable many faults to be resolved remotely without a field visit.
Systems We Work On
Stericool
Our team authored the service, user and installation manuals for Stericool sterilizers. Direct technical experience across all hardware generations and software versions.
Trans
Design-level expertise in control system design, CE technical file preparation and mechanical engineering for Trans steam sterilizers.
Getinge
Technical service experience with Getinge GSS67, HS66 and HS33 sterilizers and the 46 and 88 Series washer-disinfector systems.
Spare Parts
Spare Parts Solutions
Where available, we source original spare parts for the devices we service; for components that have been discontinued or become difficult to procure, we evaluate technical compatibility and develop alternative engineering and modernization solutions.
