Alternate spellings are listed beside the main code when our database groups them in the same guide. They are not interchangeable on every model. Open the guide to check applicability, likely causes and owner checks; a code identifies a condition, not automatically a part to replace.

Before arranging service
Save a photo of the full code and rating label, and note when the warning appears: at startup, during operation or at the end. Tell the technician whether the appliance completes a cycle and what you already checked. This helps distinguish a recurring fault from an isolated warning.
A low severity label is not a safety clearance. If there is smoke, a burning smell, a leak near electrical parts or a gas smell, stop using the appliance and seek appropriate help. Use repair-cost ranges only after the fault is understood.
