I have a Whirlpool TL, 1988, 5500XSWO, and there's not much to dislike...it's a great, basic machine.
And I'd never speak ill of my machine, BUT IF I DID:
The control panel is a high-gloss, black, painted, ribbed strip of metal with shiny black knobs, trimmed with faux chrome. The timer has a deep recess beneath the main knob and a faux chrome ring surrounding the dial, and this ALL collects every bit of possible dust, lint, water marks, etc. and requires CONSTANT cleaning, or it looks totally neglected. The recess under the dial gets a little skeevy as well over time, and has to be scrubbed out with an old toothbrush reserved for this purpose.
It's not a functional problem, but quite the annoyance, when you're trying to maintain the piece for historical reasons and sentimentality.
A few years later, white-on-white came into vogue here in the States, and it was an improvement, aesthetically at any rate, and in terms of caring for the control panel, at any rate.
