Electrical layouts and components can vary between models and production versions. A diagram found for a similar machine is not authority to work on the appliance.
Understanding this situation
Internal diagnosis and repair involve risks beyond ordinary programme selection or user cleaning. A mistaken connection can create a hidden hazard even if the display subsequently works.
A useful next step
Provide the correct model and symptom to a competent service provider. Do not remove covers, test live terminals or substitute wiring based on colour alone. This guide supports an enquiry; it is not an instruction for internal electrical work.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
