Write down naturally occurring events rather than running deliberate repeated tests. Record the date, normal load, water conditions, control used and what the appliance did before you stopped using it.
What the observation tells you
The sequence matters: for example, whether a noise came before a stop or only after the control was pressed again. Include recent sink work or a changed accessory without assuming it caused the fault. Keep any safety-related event prominent in the record.
A useful next step
Share the short timeline with the engineer. A stopped or unsafe appliance should remain unused even if gathering more examples would make the record longer.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
