Keep the interrupted programme stage in mind and follow the model's instructions when power is safely restored. Different machines can resume, wait or require a documented user choice.
Understanding this situation
A locked door may still be containing water even though the display went dark. Do not force it or assume the load completed because electricity has returned. A power event can also affect an electronic clock or saved setting without proving permanent damage.
A useful next step
Record any new warning and check the programme status before continuing. If the machine trips, leaks or smells unusual after restoration, leave it unused. Use only documented recovery controls rather than repeatedly cycling the supply.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
