Dishes come out dirty and wet - LG LDS4821ST Stainless Steel 24 in. Built-in Dishwasher

SOURCE: no hot water, plates cold and dirty and wet

If you've installed it recently make sure the hot water tap was plumbed in and not the cold water tap, check the hot water tap temp in the house to make sure it's getting warm, there also should be a heating element located inside of the dishwaher that heats up to help the dishes dry at the end of the wash cycle, which is controled by a thermostat. If the heating element or the thermostat are bad your dishes won't dry.

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...
