In reply to PaulJepson:
But there's plenty negative to say. They make small capacity expensive and unreliable washing machines, so not even good if you don't want to use the dryer. Absolutely rubbish as a dryer especially if you have more than half a load in it.
I'd rather get a washing machine than a washer dryer and dry outdoors or on drying racks about the house. I bought a combined washer dryer *once*.
For a down jacket, use Nikwax's wash and proofing according to instructions and give it a blast in the tumble dryer once air dried (if the garment can take it) in your local launderette. Can't imagine you are washing machine fulls of down jackets every week, so if this is a once in a blue moon thing, don't factor it into your washing machine decision . If you use a tennis ball in the dryer make sure nobody is around to chase you out of the launderette
