Telling them it "Smells like smoke", "It's hot enough to burn myself on" or since I used to work printer support "It's leaking ink/grease/something".
Will skip a lot of the BS and get you a replacement asap, since they don't want to deal with the legal fallout of it setting your house on fire (or staining a new couch) while troubleshooting. At one fruit themed computer call center we had a "Red Flag Word List" in which if a customer used any of the words, it got transferred immediately to Tier 2. They were all words like Smoke, fire, melting, sparks, swelling (batteries).
