ccereghino hi there... my dishwasher is around 2.5 yrs old but has been used around 10-15 times... during the last year I've wanted to use it but it is not washing well, and i end up having to take everything out aftre 2 hour cycle and have to wash again manually. today I tried opening it during cycles and noticed the vanes are not (or seem not to) be moving. What may be the problem? I put in more salts and brightener. I am using Cascade powder. I live in Chile, hard water. What to do? MODEL is WLB12A
