The condition of the 9900
I'm surprised at how good the condition the W/D is. The door button is intact, the panel has no cracks, just a bit of dust. I think the plastic on the worktop it broken a bit, but it looks good.
The washing dial is different as I think it belongs to washer dryers after 1992, as the symbols have the temperature written on it, as opposed to programme numbers which were on all the Hotpoints made before this date.
