Likely causes (ranked): 1) Faulty door latch / lid switch — machine pauses when it thinks the door opened. 2) Overheating motor thermal cut-out. 3) Clogged drain pump tripping the cycle.

Pro tips
- Be specific about the symptom and timing — "stops after 10 min on spin" beats "stops working".
- List what you already tried so the expert skips those and goes deeper.
- The reusable prompt is portable — paste it into Claude, GPT-4o or Gemini to keep troubleshooting.
- Works for any domain — appliances, vehicles, IT systems, machinery.
