Favorit 35020 has a leak on the water hardness dial , how can we repair it?

Our Favorit 35020 dishwasher has a leak on the water hardness dial and so the dishwasher keeps filling up with water unless we turn the supply off at the inlet valve . How can we repair
this ?

I have the same problem with a Favorit 40010 dishwasher - did you fix this?
