confused about power rating for washing machine in datasheet
The drum has a volume of 332L. To fill it entirely with water for a boil wash from 10°C to 90°C would be 80K×332kg×4.2kJ/kg/K = 112MJ. Assuming it wants to be about a quarter full, 27kW would take about 1000 seconds to heat it up, which if anything seems a bit slow - alternatively, in five minutes of filling with heated water using 27KW to heat it, then it would have 24L of water in the drum. (I don't honestly know the volume of water it would use, but somewhere between 1/4 and 1/20 of the drum volume seems reasonable). 

But certainly something of that order of magnitude is reasonable for a machine of that size. 600W would heat half a litre of water in five minutes, which is not enough to boil wash 37kg of clothes.
