Sources
Each public display keeps a direct connection to the official evidence used to assess it.

Official materials first
Eligible evidence comes from official US manufacturer support articles, error-code indexes, owner manuals, or narrowly scoped service material. Search snippets, retailers, repair companies, forums, social media, and AI summaries are not publication evidence.
Scope matters
The same display can mean different things across brands, appliances, model families, and markets. We retain the source's actual scope and direct users to the manufacturer's model or manual lookup when exact applicability is unknown.
Freshness labels
“Official source last checked” is a source-verification date, not this policy's Last updated date. “Automated evidence review completed” and “Owner-delegated approval” describe separate recorded events. “Manually reviewed” appears only for a real human review. A changed or unreachable source can withhold affected guidance until review completes.
Manufacturer support, manuals, and warranty resources
These general official links help you locate exact-model information. They are not evidence for a particular error-code claim.
