The user experience of dishwashers

June 10, 2010 | Author: Eric Reiss

I counted the number of dishwashers I have personally purchased over the past 25 years.

Five.

Two of them have been great. Three of them have been lousy. The last one I bought (about two months ago) is the worst of the lot. You’d think I’d learn to choose a good one, but this just hasn’t happened.

What I want from a dishwasher
I figure a good dishwasher should do four things:

- hold a lot of dishes

- wash dishes

- dry dishes

- not break dishes

As someone in the user-experience industry, I don’t think this is an unreasonable set of basic requirements.

“Easy to use” is also a good quality. I’ll get back to that.

Usability testing in real life
My mom had an old GE dishwasher which served her faithfully for over 30 years. When it broke a couple of years ago, I bought a new GE for her. But she insisted the dishes didn’t get clean. So I investigated the next time I returned for a visit. It seems you have to slam the door shut much harder than a 90-year-old is able. Honestly, I practically had to kick it shut myself. In other words, the machine never actually washed the dishes because my mother lacks the strength to shut the damned door.

Lesson One: Make sure you can actually start the machine.

The decline of civilization
In 1985, I bought my very first dishwasher for myself. A Bauknecht. Good German machine. Very quiet (39dB). And it was a dream to operate. It did everything you’d want a dishwasher to do. The first time I used it, I was convinced that every dish in the world deserved a ride in this wonderful contraption.

Ten years later, it died. Don’t know why. Just did.

I bought a new Bauknecht. Twice as expensive. There were several icons on the panel I never did figure out. Although touted as having the lowest noise level on the market, it was a lot noisier than the unit it replaced. In-depth interviews with my dishes indicated that they were satisfied with the quality of the washing, but not ecstatic.

Lesson Two: Don’t believe the brochure.

New house, new dishwasher
A year later, my wife and I sold our flat and moved to a house where we immediately started remodelling the kitchen. And we bought a Danish-made dishwasher from Vølund – completely hidden front panel, very elegant.

The Vølund was brilliant. The best machine yet. Easy to load, intuitive affordances (e.g. I could figure out where to put stuff inside the beast), great results. In fact, the only minus was that any Martini glass placed in the front-left corner of the upper rack would ALWAYS crack.

Two months ago, our Vølund died after 14 years of faithful service. Again, no particular reason, the dear thing just stopped working. Weeks passed before I could bring myself to let someone take it to the dump.

The trip to the store was a…trip
My wife and I liked the invisibility of our old Vølund (fully hidden front panel). So down we went to the local appliance store to find a replacement. Sadly, Vølund doesn’t make dishwashers anymore.

Why does a dishwasher WITHOUT a cabinet cost more than one WITH a cabinet? By a factor of about 25%? Price moves up to around EUR 600 for the cheapest “integrated” model.

“Ohh. You don’t want to buy that one. It has a nasty cheap plastic pan at the bottom. You really want a full-stainless washing chamber,” said the helpful salesman. Add another EUR 200 (and a new expression to my growing “I know all the cool technical stuff” vocabulary).

Lesson Three: stainless is better than plastic (I guess…)

LG – “Life’s Good” – for someone else
We briefly considered Miele, but I had worked in an ad agency that went through Miele dishwashers at the rate of one every three years (as we were doing their advertising, we felt obligated to use their products). So, in search of genuine quality, my wife and I decided on an LG from Korea. It cost on the wrong side of EUR 1000 but, hey, it was top of the line. Only problem, it doesn’t really do any of the stuff a dishwasher should do.

“Low noise level” says the brochure. But this is noiser than that 1985 Bauknecht.

“Saves energy.” Only if you don’t use it. The “eco” program doesn’t get the dishes clean. The “auto” program takes hours and hours to complete unless you want to dry stuff by hand.

Lesson Four: see Lesson Two.

Affordances…meh
The insides are arranged so that it holds lots of dishes, but I wish LG would send me a photo showing me how they intended the various 21st-century racks and shelves and baskets to be used. I can’t figure it out. In practice, it holds about 20% fewer items than my dear old Vølund. I’m seriously wondering if Korean dishes have a very different shape than Danish dishes.

Glasses break. All kinds of glasses. In many different locations within the machine. That’s why Martini glasses get washed by hand these days. Always. Think about it: I just spent EUR 1000 on a device that is now making me wash glasses by hand!

When this contraption runs, it smells like there’s some plastic burning. I’m afraid to run it at night or when we’re leaving the house. The smell makes me nervous, even though the installer says this is “normal”. Does that mean all my other dishwashers have been “abnormal”? Just asking…

Back in 1985, I just went out and bought my Bauknecht. And it was great. Today, there are too many choices, too many controls, too many decisions to make.

All I want is clean dishes. Is that really too much to ask?

  1. Appliances are really hard to choose. When I got married we bought Whirlpool machines. They are not fantastic at their jobs but they’re good enough. At the time they had the best interfaces ever. Not so much these days. I loved it that it didn’t let me do errors like washing wool at 90º with a 1200RPM spin. All I had to do was select the type of fabric and it would limit the choices for me as the only acceptable ones. I’m now moving to a new house and so we’re selecting new machines. This time I’m gonna go with Bosch even though the interface is a bit more complicated. Best machine UI I saw was on a industrial Miele (in my wife’s college in Cambridge) that had a screen and a rotating knob with a push button on the centre. Feels very BMWish but the UI was just fantastic and you could save your frequently used programs to the front screen. Seriously, does anybody ever use more than 3 programs regularly?

  2. Nice story. My current dishwasher is actually pretty good, but it has a new annoyance: it is SLOOOOOOOW!! It takes 2+ hrs to finish. Ironicallly, it is so quiet that sometimes I accidentally open it figuring that the breakfast dishes must be done before lunch!

    My takeaway from your story: not all change is progress.

  3. I feel your pain. I am about to buy a new dishwasher and dreading it. I feel like I need to shop with a box of plates and glasses in tow to test configs in the store. And I want to know the washing powder isn’t going to end caked up in its dispenser, and that the glasses really will rinse clean, and that the eco wash still cleans stuff effectively. I wish there was a way to test drive dishwashers.
