I have an Aquarius Dishwasher which is not cleaning dishes etc., properly. I have cleaned all filters, checked the spray arms are not clogged, but cannot see what the problem is. Instead of running the outlet hose through the standpipe, I also tried running the outlet hose along the ground out the door in case there was a blockage in the pipe but it seemed to empty OK. The only fault I can see is that although I fill up the salt compartment, the salt light comes on with the next wash indicating the salt is empty already. I am also using a good detergent which has the grease inhibitor. Now and again the dishes do come out clean but I cannot rely on the machine working properly. Can anyone suggest what the problem is? Many thanks.
