No. A heated laundry programme is not a safe way to dry electrical components or verify a flood-damaged appliance. External dryness does not establish internal safety.
Understanding this situation
Water can leave contamination and hidden damage even after evaporation. The type and depth of flooding and whether power was present are relevant facts for appropriate assessment.
A useful next step
Keep the dryer isolated where safe and obtain qualified advice before reuse. Do not remove panels, apply a portable heater inside or repeatedly switch on to see whether it has recovered.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
