Samsung Dishwasher is Not Cleaning Well

Make sure the drain hose has no bends or kinks, with a minimum diameter of 4cm. The top of the hose needs to be at a height of around 30cm to 80cm, and the loose end of the hose must not be submerged in water to avoid back flow.

Ensure that the water supply valve is fully open by turning it counterclockwise. The appropriate water pressure is 20 PSI to 120 PSI.

Make sure the filters and the nozzle of the spray arms are not clogged. It is recommended to clean the filters and spray arms of your Samsung dishwasher regularly for optimal performance.

If the spring on the dispenser door is clogged, use a small brush to clean the soap dispenser and spring. Replace if the spring or dispenser door is damaged. Leftover detergent in the dispenser may clog the detergent dispenser.

If the tableware is incorrectly placed in the dishwasher, the nozzle touches the plate and does not rotate.

Open the door and leave 2 cups of white vinegar in the bottom of the dishwasher. Close the door and complete the cleaning course. If vinegar is ineffective, use 1/4 cup (60ml) citric acid crystals instead of vinegar.
