An app connection problem and a local appliance operating fault are different issues. Some models can perform ordinary programmes from their own controls when remote features are unavailable.
Understanding this situation
Check the exact model's instructions rather than assuming that every connected washer depends on the internet for basic operation. A network message should be recorded separately from water, door, heating or electrical warnings.
A useful next step
If safe, use the documented local controls and manufacturer connection help. Do not repeatedly reset the entire appliance or share account credentials with an unofficial support site. Report whether normal control-panel operation remains available alongside the connection problem.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
