Being a bit hard of thinking ATM, and the only two times I've touched a
washing machine in 20 years was to change bearings or plumb in a new
one, ...

SWMBO is telling me that there are white powdery streaks on some washed
items

What is it ?

Should cleaning out the detergent dispensers and running it empty for a
cycle clear it out, or is there something deeper I haven't thought of ?
