I suspect it’s because they had moisture sensors so it would extend the dry time if it was still wet inside beyond a preset minimum of moisture. Most laundrymats this hasn’t been an issue. The ones in my apartment are, tho. The washer runs exactly for 25 minutes. The dryer says it will run 45 minutes, but when I come back an hour later it’s still going and now the timer says it has 20 minutes left.
That’s weird! I’ve had a dozen dryers over the years, all timed exactly as they said.
