KBV Home Reference uses official manufacturer documentation as the primary source for appliance facts.
Primary sources
Typical sources include manufacturer product pages, Owner Center or support pages, specification sheets, installation instructions, owner’s manuals, cycle or control guides, parts portals, and official accessory compatibility tools.
Why exact model numbers matter
Manufacturers may publish several revisions of a model. Bosch, for example, can use an E-Nr. suffix, while other brands use complete model and revision identifiers. Compatibility claims should be checked against the full model identifier whenever possible.
Each reference article includes the official sources checked for that page.
