Our dishwasher is approx 3 to 4 years old.
The top rack usually washes better than the bottom rack but sometimes even bowls and glassware on the top rack have residue on them.
Thanks for your reply but as far as i know the dishwasher takes in cold water and then heats it.
It does not take in hot water.
so what should i do next?
I don't know if thats the problem as the dishes are very hot to the touch when the washing cycle finishes.
So it seems that the water is heating up ok.
Thanks will try that first and let u know how that goes thanks.
I used rinse aid and added salt as well as we r in a hard water area and its working fine now. thanks very much for your help.
