Make sure the door is completely closed if the machine will not start. Close the door tightly.
Inspect the water source to make sure it is turned on if the machine does not fill with water. Turn the water on fully.
Check the water inlet hose for kinks if the machine is not receiving water. Straighten out any kinks.
Inspect the water drain hose for kinks or obstructions if the machine does not drain. Straighten the hose. Remove any debris from the hose.
Make sure the spray arms can move freely inside the dishwasher. If the spray arms knock against dishes, it will cause a rattling noise and the dishes will not get clean.
Check the dishwasher to make sure it is level if the door is hard to close. An unlevel machine will prevent the dishwasher door from properly latching.
Reduce the amount of dishes in the unit if dishes are not getting clean. Make sure there is enough room for water to access each dish.
Adjust the settings to a stronger wash cycle if dishes are not getting clean enough.
