Oh no Sterling, I can tell how frustrated you are with your dishwasher. I know that adjusting to a new appliance can be frustrating. Sandy residue, is left over food particles. For some reason the food materials are not pumping out of your dishwasher with the water. Either there is a clogged filter, a clogged spray arm, or some buildup of crud in the inside. Here are some ideas that can positively impact your cleaning and drying effectiveness. The “sweet” spot for water temperature is between 120-125 degrees (at the water heater) for the best cleaning and drying potential. Make sure you run the water in the sink until it is hot (like you would do before getting in the shower). The hot water line to the dishwasher must provide water pressure between 20 and 120 psi. Don’t forget the rinse aid, in hard water you may need to increase the amount dispensed (page 15 in your Owner’s Manual). Using the high temp wash or sanitize can also improve cleaning and drying performance. Is the heater (inside on the bottom of the dishwasher) covered by a heavy mineral or calcium scale (looks like white spots on the heater)? If it is, start a cycle with no dishes in it. Once it has finished the initial fill, add 1 cup of white vinegar to the bottom and let it finish the cycle. Parts of Canada have very hard water, some granular detergents can combine with hard water minerals and form a residue that would stick to the interior of the dishwasher and the dishes. Take out the spinning arms and rinse them thoroughly in the sink. You will notice if they do not spin freely when they are in the dishwasher. If the dirt is always on the same part of the top shelf, there may be one or more choked jets. Check the instructions (page 16 in your Owner’s Manual) to make sure you have removed and cleaned all the filters. If these steps have not helped, or you have further questions, please reach out to our Canada Customer Care at either CAC.CANADA@ELECTROLUX.COM or call 800-265-8352.
