Door fogging describes moisture and temperature at the glass, not a specific failed part. Interpret it alongside the selected stage and actual result.
Understanding this situation
Opening a hot or locked appliance to check the vapour is unsafe. A misted pane is different from moisture escaping into cabinetry or water pooling outside, which needs its own account.
A useful next step
Record where the moisture appears and whether the programme completes. Do not wipe or inspect hidden electrical areas while wet. Report persistent external condensation or leakage with the model and fitting arrangement rather than diagnosing from the glass alone.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
