try turning the rinse aid up 1 number at a time.
if this doesn't do it try washing the glasses on the bottom shelf.
also , is it just one area of the dishwasher that this occurs in or anywhere on the top shelf?
one tip for you ab-ers when you put the cuttlery in holder try putting knives in one row, forks in next and spoons then teaspoons, get the idea?
doesn't wash any better but when you take them out they are allready sorted,easy to put away.
thats my help on the domestic front, now i'm off to the pub. !!!
