Maintenance Tech Tip: Use Failure Codes to Drive Better Preventive Maintenance

One of the easiest ways to improve reliability is to consistently track failure reasons whenever equipment goes down. A simple set of standardized failure codes can reveal patterns that would otherwise go unnoticed.

Why it matters:

  • Identifies repeat issues tied to specific components

  • Helps determine whether PM intervals are effective

  • Reduces guesswork during troubleshooting

  • Provides actionable data for improving uptime

Examples of useful failure codes:

  • Electrical failure

  • Mechanical wear

  • Lubrication issue

  • User error

  • Contamination

  • Misalignment

  • Overheating

Best practice:
Start with a short, controlled list of codes so technicians can select the right one quickly. Expand only if the data shows a need for more detail.

Better failure tracking leads directly to more targeted PMs, fewer breakdowns, and stronger justification for repair vs. replace decisions.
