... Evaluating risk and the Maytag dishwasher recall.

I would be willing to bet that if all 1.7 million owners turned off the circuit breakers as instructed by the recall, since a very large number of those people (some elderly) would have to go up and down stairs in order to do that (in some cases multiple times, since many do not have properly labeled circuit breakers), there would be a much greater chance of someone being injured from falling on the stairs than there would be from a dishwasher fire that could result if no one shut off the circuit breaker.
