Samsung Dishwasher Not Filling With Water! Causes And Fixes!

In order to perfectly clean dishes, not just Samsung, every dishwasher requires a specific amount of water. But, if the washer is not filled with water, dishes may not get clean or your washer may stop working.

Mostly, the issue of the Samsung dishwasher not filling with water arises because of a faulty water system, defective float switch, faulty water inlet valve, etc. Here, most of them aren’t too serious and easy to solve.

But, you have to follow proper guidelines to troubleshoot and solve them which are described throughout this article. So continue reading to learn more.

Troubleshooting And Fixing Samsung Dishwasher Not Filling With Water Issue

Inside a dishwasher, spray arms rotate and distribute water and detergent evenly all over the dishes and remove food particles. But, if the washer fails to fill with water, the whole washing system becomes disturbed.

And a dishwasher fails to fill with water because of several reasons. To help you with this, here we described the most possible reasons with their troubleshooting and solving procedures. So, follow these carefully.

1. Faulty water supply hose/line

This is the most possible reason why your Samsung dishwasher is not filling with water. In a dishwasher, the water inlet valve requires around 20 to 120 PSI of water pressure to operate properly.

But, if your house’s water pressure is too low or any kinks, blockages, or damage in the hose, can restrict water flow and create water filling issues.

To troubleshoot and fix this issue, first, check the water supply valve and make sure it’s “ON/OPEN”. You’ll find it under your dishwasher or under the sink.

Now check the water pressure. To do it, remove the water line connection from the dishwasher, turn on your main water supply valve, and run the water into a bucket.

If the water pressure is low, check the hose for any visible signs of bends/twists or damage, and if necessary, straighten it or replace it. Also, use a thin wire or a pipe cleaner to remove any obstructions inside the hose.

Besides, ensure that the hose is properly connected to your house water supply line and the dishwasher’s water inlet valve.

If the problem still exists, then probably there is an issue with the float mechanism.

2. Obstructed overfill protection float

The overfill float (also called Mushroom Float) is a safety mechanism in the dishwasher that monitors the water level during a wash cycle. It’s located at the front right or left corner of the dishwasher tub and is made of plastic with a dome shape.

Generally, when the dishwasher receives enough water, this float rises up and shuts off the water line. However, when it malfunctions, it sends a signal that there is enough water, so as a result, the dishwasher stops filling up.

Most of the time, this issue arises if anything gets stuck in this float mechanism and obstructs its free movement.

To identify any issues with it, find the float and make sure it can move up and down freely. But, if it’s not moving up and down properly, take a good look around it for any jams, and if you find any, clear them out.

3. Faulty float switch

If the float mechanism is working properly but the dishwasher is still not filling, then it may mean that the float switch has become faulty. This float switch is a small device located under the float and controls the water supply.

When a certain amount of water is filled, the float activates this switch, which then shuts off the water supply. But, when it becomes faulty the dishwasher will overflow or not fill with enough water.

In this case, inspect the float switch for any signs of damage. Also, test it for continuity using a multimeter and the wiring connections to it.

Here, if you have determined that the float switch is defective, you will need to replace it. This may cost around $20 to $30.

4. Defective or clogged Water inlet valve

In a dishwasher, the water inlet valve controls the water flow into the appliance. When you start the wash cycle, the control board sends a signal to the water inlet valve which allows water to flow into the dishwasher.

But, it can become faulty either mechanically or electrically and can’t perform its task perfectly. As a result, the dishwasher can’t be filled with water.

To troubleshoot and solve this issue, first determine its faults. So, take a multimeter and check the valve for continuity. If it shows a result between 500 and 1500 ohms of resistance, then it’s okay.

But if it doesn’t show any result, this means the valve is faulty and you have to replace it.

If the valve is electrically good, but the issue still occurs, then check it physically for any mechanical damage. To do it, inspect this valve and look for any signs of damage, such as cracks or leaks. If you find any issue, replace it.

Here, if it physically and electrically looks fine, then check the valve filter which is used to block any dirt from water. If this filter looks dirty, then clean it.

This should solve the water not filling issue. But if the issue still exists, then try the next solution.

5. Faulty door switch

The door switch is a safety mechanism that lets the dishwasher start when the door is fully closed.

Here, if this switch is broken, even if you close the door, the control board can’t detect it. It thinks that the door is still open and as a result, it doesn’t start the filling process.

In this situation, make sure you close the door properly. But, if it doesn’t work, then check the door switch and look for any visible damage, such as cracks or loose wires.

If you find any issues like loose connections or fault alignment, try to solve them. If it looks fine, but the issue still exists, then check the switch using a multimeter.

Here this video might help you to do it:

After checking, if you found that it became faulty, then replace it. This might cost around $40 to $50.

6. Control board problems

After following all the solutions mentioned above, if the issue is still not solved, then there’s a high chance that the control board is malfunctioning.

A control board controls all the functions inside a dishwasher. When it becomes faulty, it can’t communicate with other sections or switches in the dishwasher, like float switch, door switch, water inlet valve, etc.

Because of this, you may face several issues with your dishwasher, like, error code, water filling issues, sudden shutdown, and many more.

In general, this control board becomes faulty because of short circuits, blown parts, water, physical damage, etc.

And to inspect and solve this issue, you have to take it out l and inspect it carefully, for any signs of damage (like water damage or blown parts).

Here, sometimes by replacing the damaged parts or repairing any minor issues, you can easily solve a control board issue. But, if the issue is more complicated, it’s better to replace it.
