Jon,
there is no question about the quality of vintage Whirlpool products - and their cooktops, microwaves and venthood/microwave combinations are really unique - at least here in Germany.
But the company made some decisions back in the 1990s that had a direct effect on product quality.
Whirlpool decided to move into the European market and chose Germany as one of their first...nearly said victims...distribution areas. There, that sounds much more impartial.
They introduced the "service by free agent" concept. Instead of having dedicated serivce people (yes, they do again today so nobody write me this is wrong, please) they just rang up any old fool in your area and had them come look at your machine. If the in-duh-vi-du-al was competent enough to find the problem, they then had to contact Whirlpool who whould then send the replacement parts to them...
You had at least two appointments (and in Germany service people only worked (1990's folks, not today, so no "but that is not true's here, ok?") M-F, 9-4.
You got to miss two days of work. Minimum.
But the machines were so badly made - not my opinion, but that of every single consumer testing service -
that Whirlpool quickly decided they needed to rethink things.
They bought Baukneckt - an old brand with an excellent reputation (especially for service) and began selling their thoroughly rotten machines under that brand name.
Lot's of folks fell for it.
At the same time, they introduced an 8-year extended parts warranty (was expensive) and brought back "real" service people and a hotline.
Ok, looks like they were trying, huh?
Wrong.
Soon as things got back to where folks had a little trust in them again they closed down all their quality European plants and went back to worst quality production.
Because the heating and cooling appliances - esp. for Ikea are pretty good, folks tend to make a mistake and buy their bad laundry stuff.
Once.
Ok, I know I will now get all sorts of flames for this, but that is the way it was and is.
I confess - I worked with them for several years and got to know their internal policies over here in Europe. (I left them, they still wanted my services, they always paid me promptly, no axe to grind there...) Certainly there are a lot of good folks who know what they are doing in the company, but the managers running the show from the 'States are neither interested in their shareholders nor their workers nor their customers.
Ok, now everyone can say what a horrid person I am and how wonderful Whirlpool is...
