Failure Code
A failure code is a controlled classification used to record how an asset or component failed in a consistent, reportable way.
What this term means in maintenance
A failure code is a controlled classification used to record how an asset or component failed in a consistent, reportable way.
Purpose of failure codes
Failure codes allow teams to group work-order history and identify recurring patterns.
Examples may include:
- Leak
- No start
- Overheating
- Excessive vibration
- Low pressure
- Electrical trip
- Broken component
- Incorrect reading
- Blockage
- Reduced output
Code structure
Organizations may use separate code groups for:
- Symptom
- Failure mode
- Cause
- Action taken
Keeping these concepts separate improves reporting.
Practical example
A pump work order records:
- Symptom: Low discharge pressure
- Failure mode: Impeller wear
- Cause: Abrasive process solids
- Action: Replaced impeller
Code-list design
The list should be short enough for technicians to use and specific enough for analysis. Codes may vary by asset class.
Common mistake
Using one large generic list across all equipment creates irrelevant choices and inconsistent records.

Failure Mode
A failure mode describes the specific way an asset, component, or function fails to meet its required performance.
Root Cause Code
A root cause code is a controlled classification used to record the verified underlying cause of a maintenance failure or recurring problem.
Pareto Analysis
Pareto analysis ranks problems by their contribution to total loss so teams can focus on the few causes creating the greatest impact.
Failure Code FAQs
- What is a failure code?
It is a controlled classification used to record how equipment failed.
- Should failure and cause use the same code list?
No. Separate symptom, failure mode, cause, and action lists normally produce better data.
- Should every asset use the same failure codes?
Not always. Asset-class-specific codes may be more relevant and easier for users.
