Its an Asko6021. The top of the line Asko does have hot water in. The way the machine fills(a little fill then stop, repeat)and the distance to my hot water tank would make this almost a waste of time I think. I havent ever used it over 40C so I dont know what its like above that. Had no problems with musty odors, maybe its the way the door seals on the Asko? Have you worked out what it costs to heat 80 litres of water?(My maths says it takes
60kWhr)
