Record the last normal use, the first changed result and any event immediately before it. A short sequence often carries more useful information than a long list of possible components.
Understanding this situation
Examples include a new detergent, a different bulky load, a water interruption or a change to the appliance's position. These events are clues, not proof of cause, and should be separated from what the machine actually did.
A useful next step
Note the programme stage, warning and whether the event repeated naturally. Do not recreate an unsafe leak, electrical trip or violent movement to improve the timeline. Existing observations are sufficient to explain why an assessment is needed.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
