Hello!
For a better understanding, I kindly recommend the video of Keith : a great man who explains very well in proper English (not like mine!
) how to overheat the steam out of the boiler. (I recommend his videos , we learn a lot and it is clear)
Taking into account that the wet steam coming out of the boiler is always charged with droplets of water = sucking effects added to washing machine turbulences inside. And depending of the (too) high level inside, it is suitable to overheat ....
a bitThe goal is to have a steam with a temperature slightly above the saturated one to allow an expansion with no condensation.

Note also , as Steamboatmodel says, that the higher the steam pressure is , the higher is the temperature ,so this keeps the machine hot and helps limiting the condensates.
Thinking that the steam lubricates is like walking bare feet on the gravel. You walk but you'll go further and smoother with a pair of shoes!
Sorry to appear as a "Know all", this is not the case but I learn everyday and if I can share to avoid falses ideas, I'll be glad to contribute at my modest level. This is why I am often on this forum to benefit of the experiences of some great "STEAMERs"
Thanks for share your experience.
Best regards.
