A friend parents had one of these when we were kids, late 80's early 90's. Her Mum always used to cram it full, she was one of those who washes everything together, lights, darks, towels, you name it, it all went in lol.. If I remember rightly, she used to mostly use the quick wash programme, which, again if remember rightly, only took about half an hour. It used to count down the time on the display. From what I can remember,the Non fast coloureds cycle wash quite long, compared to other machines of the time. To operate the machine, you switched it on with the button in the middle of the facia, then I think it was the left hand button under the display that selected the programme, the buttons in the middle were options, sorry, cant remember what, I think one may have been half load, but not 100% sure and the red button to the right started/paused the programme. Theirs was the only one I have ever seen, I expect they were very expensive at the time.
