If your Samsung dishwasher won't fill, start with the parts and checks that fail most often. The most common cause is a bad or clogged water inlet valve, which keeps water from entering the tub at all. Next, check the safety float in the front corner of the tub. If something is stuck under it, the dishwasher may think the water level is already too high and refuse to fill. If that looks clear, make sure the water supply shut-off valve under the sink is fully open. After that, test the float switch, since a stuck or failed switch can also stop filling. Less often, the main control board or control board fails to send power to the water inlet valve. If your Samsung dishwasher is not filling with water, has dishwasher no water symptoms, or seems like a dishwasher water inlet valve problem, these are the first places to look.

Some dishwashers have a safety float in the front corner of the tub to prevent the dishwasher from overfilling with water. If an object is stuck under the float, the dishwasher may not fill with water. If you find anything stuck under the float, remove it and the dishwasher should start filling properly.

03 - Samsung Dishwasher Main Control Board
A dishwasher's main control board provides power to nearly every electrical component in the dishwasher. A faulty board may be unable to supply power to the water inlet valve, preventing it from opening and allowing the necessary water to fill the tank.
You should confirm that the dishwasher's water supply shut-off valve is in the "On" or open position. The water supply shut-off valve is usually located under the sink and is connected to the hot water line.

05 - Samsung Dishwasher Float Switch
The float switch is a safety designed to shut off the water inlet valve if the dishwasher is overfilling. If the float switch is defective or stuck, it might stop the dishwasher from filling correctly. You can use a multi meter to test the float switch for continuity. If the float switch is defective, replace it.
