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.
