Fault identification and diagnostics

Fault identification and diagnostics

Fault Identification

  • Observation is the crucial first step, noting any irregular behaviour, abnormal sounds, smells, or visual damage.

  • Gather operational data during normal operations and when problems occur to identify patterns and track changes over time.

  • Use testing equipment to monitor the system or component’s performance, measuring parameters like temperature, pressure, voltage, or current.

  • Understand warning signs such as system alerts or error codes, abnormalities shown by meters and gauges, and erratic system performance.

  • Keep abreast with the manufacturers’ guidance and any identified common faults that correspond to the symptoms.


  • Carry out troubleshooting to identify the cause of the problem, testing individual components and functions to isolate any issues.

  • Perform system performance assessment, comparing actual operation with expected or standard operation

  • Apply diagnostic procedures from manufacturer manuals, documentation, or software tools.

  • Utilise comparison methods, benchmarking against a normal system.

  • Execute predictive diagnostics to foresee potential issues and implement necessary precautions or solutions based on the analysis.

Interpretation of Findings

  • Understand the significance of error codes, alert signals, and aberrations in readings.

  • Determine whether the issue is temporary or chronic, assessing the problem’s frequency and duration.

  • Identify if the system or part defect is due to wear and tear, environmental factors, misuse, or manufacturer’s defects.

  • Distinguish between simple faults that can be repaired in-house and complex ones that require expert intervention

  • Recognise when system behaviour indicates a severe breakdown risk, necessitating immediate shutdown to avoid damage.


  • Implement and test solution(s) for identified faults

  • Employ regular preventive maintenance schedules based on fault identification and diagnostics to prevent similar issues in the future.

  • Escalate complex faults and issues to specialists, ensuring to provide them with comprehensive fault and diagnostic data.

  • Do follow-ups post repair or maintenance to ensure the issues have been fully resolved.

  • Always document all the findings, action taken, and their results for future reference, aiding in better maintenance-driven decisions.
