PRIMA dishwasher prima lpr450 slimline
HELP
i have this slimline dishwasher, it was working a few days ago, i went to use it now, and i turned it on and it wouldnt let me choose what cycle i wanted and i noticed a light on the top that looks like two arrows twirled together in a s formation. I think this is the salt warning light, so i checked where the salt goes and its filled with water, how do i get rid of the water and how do i get it to work again please
thanks angela
p.s the Product number is 444447062 which apparently is a whirlpool
