We replaced a noisy 2010-vintage dishwasher with a brand-new $1,300 Bosch that got top ratings in Consumer Reports. The first installer showed up, pulled the old one out, and declared that the Bosch would never fit due to having a “closed frame” rather than the standard “open frame.” He drove back to the Best Buy warehouse and was never heard from again. I made a few measurements and checked the Bosch installation guide, but I couldn’t figure out exactly why there was an incompatibility.
I assumed that eventually Best Buy would refund our money, but that hadn’t happened after more than a month. I decided to call them up. “We were waiting for you to schedule a redelivery,” the agent said, apparently unaware that the Bosch would never fit under our counter. We agreed on a date. The second installer showed up and, without commenting on any particular challenge, hooked up the new dishwasher. Adventures in American consumerism!
The machine works reasonably well and is nearly silent, but it holds fewer dishes than the old machine and defaults to a three-hour (!) cycle time. A Whirlpool from 1996 was much faster and also better at cleaning. The new machine sometimes leaves things stuck onto spoons, etc.
“Let’s Talk about Ghastly Dishwashers” says dishwashers meeting a 2013 standard use only three(!) gallons of water. (The article also says “Trump is a smart politician” so maybe we should verify the rest of the claims?)
We end up doing about three loads per day, so I’m not sure that we’re saving water or electricity.
Separately, I think it is interesting that, in a society that is otherwise uninterested in quantitative noise measurements, dishwashers are prominently advertised with dBA ratings (40 dBA for the Bosch). If people want to know how many dBA for a $600 dishwasher, why don’t they want to know the dBA for the interior of an aircraft or automobile?
