Reducing hardness to less than 3 grains.
The Miele owners manual for the Futura Crystal says that if your tap water hardness is above (4 gr/gal [US]), the water should be softened.
My water seems to be about 3 gr/gal.
I'm thinking of getting a crystal and it has a water softener.
What happens if I soften it anyway to less that 3 gr/gal ?
Does it do something good ?
Does it do something bad ?
Or does it do nothing ?
