Common Causes
When a Samsung dishwasher does not fill with water, several common issues might cause this problem. Identifying the root cause helps fix the issue faster. Each part plays a role in water flow and control inside the dishwasher. Understanding these common causes can save time and reduce repair costs.
Water Supply Issues
The dishwasher needs a steady water supply to work. Check if the water valve is open and water flows to the dishwasher. A kinked or blocked hose can stop water from entering. Low water pressure may also prevent proper filling.
Clogged Inlet Valve
The inlet valve controls water entry into the dishwasher. Dirt or debris can clog this valve, blocking water flow. A clogged valve stops water from filling the dishwasher tub. Cleaning or replacing the valve often fixes this issue.
Faulty Float Switch
The float switch signals when the dishwasher has enough water. If stuck or broken, it may stop water from entering. A faulty float switch can cause the dishwasher to think it is already full. Testing the switch helps decide if it needs replacement.
Malfunctioning Door Latch
The dishwasher door must be fully closed and latched to fill with water. A broken door latch stops the cycle from starting. The dishwasher may refuse to fill as a safety measure. Checking and fixing the latch restores proper function.

Basic Checks
Basic checks help find simple issues with your Samsung dishwasher. Start with easy steps before calling for help. These checks often fix the problem quickly. Save time and avoid extra costs.
Confirm Water Supply
Make sure the water supply to your dishwasher is turned on. Look for the water valve under your sink or near the dishwasher. The valve must be fully open for water to flow. If closed, your dishwasher won’t fill.
Check if other taps in your house have water. If no water flows, the problem is with your home’s water supply. Contact your water provider to fix the issue.
Inspect Water Inlet Hose
Look at the water inlet hose connected to the dishwasher. It carries water from the supply to the machine. The hose must not be twisted, bent, or blocked. A blocked hose stops water flow.
Disconnect the hose and check for clogs or dirt inside. Clean it carefully with a brush or running water. Reattach the hose tightly to avoid leaks.
Check Dishwasher Door
The dishwasher door must be closed properly for the machine to fill. Check if the door latch clicks when you shut it. A loose door or broken latch stops the cycle.
Inspect the door seal for damage or dirt. A bad seal can cause water leaks and prevent filling. Clean or replace the seal if needed.
Cleaning And Maintenance
Cleaning and maintenance help your Samsung dishwasher work properly. Dirt and debris can block water flow. Regular care keeps parts clear and water filling right. It also stops future problems. Follow these easy steps to clean key parts inside your dishwasher.
Clear Debris From Inlet Valve
The inlet valve controls water entering the dishwasher. Dirt can block this valve and stop water flow. First, turn off the power and water supply. Then, locate the inlet valve near the bottom. Remove any visible debris carefully. Use a soft brush to clean small particles. Check that the valve moves freely. Replace the valve if damaged or stuck.
Clean Float Assembly
The float assembly tells the dishwasher when to stop filling. Dirt or buildup can trap the float. This stops water from entering. Open the dishwasher door and find the float at the bottom. Lift it up and down to check movement. Clean around the float with a cloth. Remove any stuck debris. Make sure the float moves freely to signal water levels correctly.
Remove Blockages In Spray Arms
Spray arms spread water during the wash cycle. Blocked holes reduce water pressure inside. Take out the spray arms carefully. Use a toothpick or small brush to clear clogged holes. Rinse spray arms under running water. Check for cracks or damage. Clean spray arms regularly to keep water spraying fully.

Electrical Components
Electrical components play a key role in a Samsung dishwasher filling with water. These parts control the flow and timing of water entering the machine. Problems in these areas often stop the dishwasher from filling properly. Checking these parts can help find the cause of the issue.
Simple tests and inspections can reveal if any electrical component is faulty. Fixing or replacing these parts usually restores normal function. Understanding these components is important for troubleshooting the dishwasher.
Test Float Switch Function
The float switch stops water overflow by sensing water levels. It sends signals to the control board. Use a multimeter to check its continuity. When pressed, the switch should show a change in reading. No change means the float switch may be broken. Replace it to fix the water fill problem.
Examine Wiring Connections
Loose or damaged wires cause electrical faults. Unplug the dishwasher before checking wiring. Inspect all wires for breaks or burns. Tighten any loose connections. Look for corrosion on terminals and clean if needed. Proper wiring ensures electrical parts get power to work well.
Reset Control Board
The control board manages dishwasher functions, including water filling. A reset can clear errors or glitches. Turn off the dishwasher and unplug it. Wait for about five minutes. Plug it back in and power on. This simple reset can fix minor software issues affecting water flow.
When To Call A Professional
Knowing when to call a professional is key if your Samsung dishwasher does not fill with water. Some problems are simple and easy to fix. Others need special tools and knowledge. Calling an expert can save time and avoid damage.
Persistent Water Filling Problems
If the dishwasher keeps having water fill issues, it needs expert help. A professional can find hidden problems. They check parts that are hard to reach. Repeated problems may mean a deeper issue inside.
Replacing Major Components
Some parts need special skills to replace. Water valves, pumps, or control boards require care. A professional knows how to handle these parts safely. They have the right tools and experience. Replacing major parts yourself may cause more damage.
Safety Precautions
Dishwasher repairs involve water and electricity. This combination can be dangerous. A professional understands safety rules and uses protective gear. Avoid risk by letting an expert handle electrical parts. Your safety is the top priority.
Preventive Tips
Preventing your Samsung dishwasher from not filling with water saves time and stress. Simple care steps keep it working well. Regular checks help spot issues early. Follow these tips to avoid common problems.
Regular Cleaning Routine
Clean the dishwasher filter at least once a month. Food bits can block water flow. Wipe door seals to prevent dirt buildup. Check spray arms for clogs and remove debris. Clean the water inlet valve gently to avoid blockages.
Use Proper Detergents
Choose detergents made for dishwashers. Avoid using too much soap. Excess detergent causes foam and blocks water filling. Use powder, gel, or pods as recommended. Store detergents in a dry, cool place.
Check Water Pressure
Low water pressure stops the dishwasher from filling. Test water pressure regularly with a gauge. Ensure water supply valves are fully open. Clear any kinks or bends in the hose. Call a plumber if pressure stays low.
