FOLLOW THE EVIDENCE
Research & verification methodology
A model, a code, and a source are separate pieces of evidence.
1. Identify the document
We start with official manufacturer support material and manuals relevant to US appliances. Research records retain the source URL, publisher, title, document type, check date, and relevant section. A link is a reference to the evidence, not a substitute for reading it.
Some support documents describe a whole appliance category. Others apply to a particular family or manual. We preserve those limits instead of treating every code as universal.
2. Verify the appliance and code separately
Model identifiers keep their meaningful suffixes and variants. An error-code record is scoped to the manufacturer and appliance type, with further family or generation limits where the documentation requires them.
Displayed spelling matters. Search can help readers find typing variations, but the article shows the documented display and any explicitly supported alternate formats.
3. Establish compatibility
A model–code relationship is recorded explicitly. A shared brand name, similar model number, or similar-looking control panel is not sufficient evidence. Relationships that need further verification do not justify an exact-model claim.
A verified relationship can support a compatibility listing. It does not automatically justify an additional indexable article.
4. Decide whether a separate guide helps
A model-specific article must contribute useful documented distinctions, such as a relevant control sequence or accessible maintenance location. If the instructions are effectively the same, a shared guide may be the clearer answer.
We review the meaning, first safe action, scope, service boundary, references, internal links, and potential duplication before publication. Automated checks support that process; they cannot establish the truth of a technical claim.
How ErrHive checks an answer
An error code is a clue within a particular appliance family. Its spelling alone does not establish what it means on your machine.
We start with manufacturer support material and owner manuals. Each diagnostic record identifies the source, its scope, and the date it was checked. We separate the documented meaning from our explanation of how to use that information.
An exact-model article needs more than a model number in its title. The documentation must establish applicability and provide useful model-specific details. Otherwise, a shared guide explains the scope without manufacturing a separate answer.
Homeowner checks stop where the manufacturer’s directions end. Internal electrical tests, refrigerant work, gas repairs, microwave internals and bypassing safety systems are outside our consumer guidance.
