No. A longer cycle can have several explanations, including selected options and load behaviour. Duration alone does not establish the pressure at the washer connection.
Understanding this situation
An observed supply interruption or other household water issue is relevant, but the appliance's warning and filling behaviour need to be considered too. Do not loosen a hose or open a connection to perform an improvised pressure test.
A useful next step
Check only normal accessible household observations and the model's permitted guidance. Report whether a supply event affected other fixtures and when the washer changed. If water is leaking or near electrics, stop use and obtain appropriate assistance before further investigation.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
