Why Dishes are dirty even after cleaning in Samsung Dishwasher?

If your dishes still have food particles on them after washing, it is probably caused by one of the following conditions:

a). An inappropriate cycle has been selected.

b). The water temperature is too low. Make sure the supply line is connected to a hot water source. Hot water will more effectively remove food particles. The hotter your hot water heater in your home is set to, the better your dishwashers performance will be.

c). The pressure of the supplied water is too low. Make sure the water supply valve is fully open by turning it counter clockwise. The proper pressure is 20 PSI to 120 PSI.

d). The nozzles that squirt water onto the dishes are clogged. Clogged nozzles hamper the dishwasher's ability to clean dishes properly. Clean the affected nozzles.

e). The dishes are loaded improperly. If the dishwasher is improperly loaded, the nozzles will hit the dishes, and will not spin. Rearrange the dishes so the nozzles spin properly.Check to make sure the nozzle arms spin freely.Try spinning all 3 nozzle arms by hand, they should spin freely. If they do not spin freely, clean the nozzles that do not spin freely.

Warning: If you have children in your household, do not set the temperature on your hot water heater above 120°F to avoid the risk of scalding.
