Hi, I have an LG LDS4821 dishwasher and it appears to stop working properly. The dishes don't seem to be cleaned at all. It seems like the spray arms are not spraying the dishes as the dishes are still dry/dirty after a normal wash cycle. I did notice that the detergent was used during the wash, and a trail of white residue was at the bottom of the tub. I can hear water pumping into the dishwasher, but when I opened it during a wash cycle, there was a puddle of water at the bottom of the tub and the dishes were still dry. Can someone please help before I can LG for servicing? Thank you,

1 Scrape and rinse dishes before putting them in your appliance. Small food particles, grease, sauces and bones clog up the system, keeping the dishwasher from properly rinsing your dishes. You don't need to prewash the dishes but be sure to rinse off any solids.
2 Use a toothbrush to clean around the dishwasher door.
Clean around the seal and hinges of the dishwasher. This area often is forgotten and holds a good deal of bacteria and food splash. A tooth- or bottlebrush is the best way to get into the crevices.
3 Clean chunks of food out of the screen and drain at the bottom of your dishwasher, recommended The Family Handyman. If the drain is plugged, the dirty water can't be washed away and ends up back on your dishes. Nut, bean and seafood shells, bits of plastic and small dishes can lodge against the drain, keeping it from doing its job.
4 Unclog the holes in the sprayer arms. If the holes are blocked by food or soap, water cannot freely spray inside the dishwasher to thoroughly clean the dishes. Leftover food on the dishes can make the dishwasher smell.
5 Keep space around your dishes. Overloading a dishwasher keeps it from running efficiently, allowing gunk to build up around the drain and the spray arms.
6 Run your dishwasher as hot as possible to break down food and grease. The recommended temperature is 120 F.
7 Run the dishwasher with vinegar added to neutralize odor. Empty the dishwasher, place a dishwasher-safe cup filled with white vinegar on the top rack, and run a cycle at the hottest setting. If you prefer, use unsweetened lemonade powder or baking soda in place of vinegar.

Hi

If you are noticing that the dishes are not clean, then there are a few things to check for. Check the soap powder if it's kept in a dry environment. Also try replacing the powder with something like a gel or liquid. Next thing to check for is the water pressure and fill valve. Check if the water is filling in and the spray arms are throwing the water with enough pressure. Try and listen to the sound if you hear a proper spraying action sound.

If it seems as a low water pressure then check the fill valve. Now, check if dishwasher is draining the water or not. While the dishwasher is working check whether the dishwasher is draining and there is not much left out water after the cycle is complete. Try cleaning the spray arm with a soft brush. The water temperature plays a major role in cleaning of dishes. The temp should be between 125 and 150 F for dishwasher to clean the dishes.

Hope this helps... Please post back if you need more information.

Hi,

Probably a blocked spray arm (part that spins around). Remove each of the spray arms and check and clean all the holes as this is where the water sprays out from to clean the dishes and glasses. When they are blocked you get poor wash results.
Hope this helps
