No. Drying mode is not a safe way to remove floodwater from electrical components or demonstrate that the appliance has recovered.
Understanding this situation
External dryness does not establish internal condition, and contaminated water can leave damage after evaporation. The machine's ordinary laundry heating function was not designed as a restoration process.
A useful next step
Keep it isolated where safe and obtain appropriate qualified advice before reuse. Report the flood depth, type and whether the supply was on if known. Do not open covers, apply heaters or run an empty hot cycle.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
