Purpose

From failure information to actionable reliability decisions.

Reliability decisions depend on more than detecting that something is wrong. Engineers and maintenance teams need a structured way to understand what failed, why it may have failed, and what action should come next. This ISO 14224 Problem / Cause / Remedy Reference Tool was built to make that process faster, clearer, and more consistent. By organizing failure classes, problem codes, cause codes, and ordered remedy actions into a practical workflow, this resource helps technicians and reliability professionals move from observation to action using a common reliability language. It is designed as a working reference for the field, the shop, and the planning table — supporting better troubleshooting, cleaner documentation, and more defensible maintenance decisions.

Disclaimer: This reference tool is provided for general reliability, maintenance, and troubleshooting support. It is not a substitute for OEM manuals, site-specific procedures, safety requirements, regulatory obligations, engineering review, or professional judgment. Recommended actions should be evaluated in the context of the specific asset, operating environment, failure history, inspection findings, and applicable maintenance standards before implementation.
