MowerFixAI is an independent diagnostic platform. Evidence grades describe the strength and applicability of the underlying source; they do not imply manufacturer endorsement.
Exact or directly applicable manufacturer evidence for the model, error, procedure or component.
Strong manufacturer, product-family or corroborated technical evidence that is relevant but not as exact as Grade A.
Useful structured knowledge that requires stronger corroboration before being promoted as high-confidence guidance.
Owner-safe checks are separated from procedures that require mains work, sealed electronics, battery disassembly or proprietary service tooling. Those procedures should be escalated to an appropriately qualified service provider.
A part associated with a fault is not proof that the part has failed. MowerFixAI recommends confirmation through diagnostic checks before replacement.
