A split or displaced door seal needs assessment before further use. The absence of a puddle on the last wash does not establish that the next programme will contain water safely.
Understanding this situation
A defect can behave differently as the load moves or the water level changes. Fabric trapped near the opening can also worsen the damage, so identify the visible location without pulling the seal away.
A useful next step
Leave the machine unused and provide its model and an accessible view of the affected area. Do not test a suspected leak with a hot or full load, and do not treat tape or glue as a durable repair.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
