ApplianceEdge assessments — lifespans, repair values, and reliability notes — are our editorial opinions, built from documented third-party sources: owner reports, industry pricing data, manufacturer literature, and official records. They describe patterns across a product family, not any individual machine; your experience may differ. Recall information links directly to official CPSC notices. We accept no payment from manufacturers, and no brand influences what we publish.
