When to stop
- Smoke, a burning smell, damaged wiring, standing water near power, or an active leak: stop using the appliance. Disconnect power only from a safe, dry location and arrange qualified service.
- Stop if a part is damaged, jammed, sharp, inaccessible, or does not match your manual. Do not force parts or remove a cabinet panel.
Every check and possible next step
Start at “Where is the spill or dirt?”. Choose only what you observed. An unobserved condition is its own answer.

Continue to Is power unplugged and a soft damp cloth ready?. - Liquid or damage is at electrical parts
Pause and arrange qualified help — Keep the appliance out of use if a safety concern remains. Give the technician the exact model, the visible symptom and any displayed code. Do not open the cabinet or make electrical measurements. - I have not checked this yet
