Dishwasher · Focused observation
Water remains after washing
Note whether the programme stopped or announced completion. Drainage, pumping and level sensing can require assessment, but visible water alone cannot identify a replacement part.
Model and requested work checked before an appointment is agreed.

How this relates to your dishwasher
Filling, spraying, heating and emptying are separate stages. Note the last stage you recognised and whether the programme ended normally.
Keep evidence and assumptions apart
Describe what you saw during ordinary use, then retain the complete model. An observation can help frame an assessment but does not establish which part is faulty.
When to stop demonstrating
Do not repeat a cycle to recreate smoke, tripping, burning, unsafe movement or leakage near electrical parts. Keep connected equipment in place and do not remove covers.
