Using Too Much Or The Wrong Type Of Detergent

You should never use more detergent than is recommended in your Samsung dishwasher’s user manual. Using too much detergent can lead to the production of too many soap suds which can cause water to leak from the appliance.

This can also be a problem if you were to use the wrong type of detergent in your dishwasher. For instance, washing up liquid will produce too many soap suds and is liable to cause the dishwasher to leak.

Dishwasher Not Level

If the dishwasher isn’t level, it can cause it to leak. This is because water will pool on one side and fail to drain properly which could cause it to leak.

You should check the level of your dishwasher using a spirit level. Check from front to back and side to side. Use the adjusters on the feet of the appliance to level the dishwasher up.

Overloading The Dishwasher

Dishes

If the dishwasher is crammed too full with dishes, plates, pots, etc, it could cause the door to not seal correctly leading to a leak.

Always load the dishwasher in a sensible way to prevent this from becoming a problem.

Blocked Or Stuck Spray Arm

If there is a dish or pan obstructing the spray arm it could lead to excessive water spraying in the wrong area. This could cause leakage.

Check that there are no obstructions blocking the spray arm and run the dishwasher again. If the leak is still apparent, you might need to replace the spray arm.

However, there is another possibility and that is the spray arm’s nozzles have become clogged. You should remove the spray arm and soak it in warm soapy water to clean it.

Then inspect the nozzles for any blockages. This could be caused by food particles, grease, fat or limescale. You can gently prise any obstruction from the nozzle using a wooden toothpick.

Make sure that you remove the blockage and don’t force it in further.

Worn Or Damaged Door Seal

The dishwasher’s door seal or gasket is designed to make a watertight seal around the door to prevent any water leaking out. Over time the seal can become worn or damaged which can break that seal causing water to leak from the door area.

You will need to inspect the door seal and check for any cracks, splits, tears or other damage. If there is any sign of damage, the door seal will need to be replaced.

Faulty Door Latch

The door latch on a Samsung dishwasher is opened by pressing it until it clicks. If the latch develops a fault, it could cause water to leak from the appliance.

If the latch is faulty, it will need to be replaced This can usually be done by anyone with basic DIY skills. However, if you don’t feel confident in your abilities, we recommend getting a technician to do this for you.

Defective Water Inlet Valve

All of the water that enters the dishwasher, does so via the water inlet valve. The control board sends a message to the solenoid to open and allow water in.

When there is enough water in the tub, the control board sends another message for the solenoid to close the inlet valve.

If the inlet valve becomes defective, it might not respond to the second message. This would mean water continues to flow into the tub leading to a leak.

To inspect the water inlet valve, you will need to remove the bottom front panel of your appliance. You will then need to check for any signs of damage and if present, the inlet valve will need to be replaced.

This is another job that can be tackled by a competent DIYer or left to a technician if you prefer.

Loose Or Damaged Inlet Hose Or Drain Hose

All of the water that enters your dishwasher goes through the inlet hose and all of the water that exits your appliance does so via the drain hose.

Over time these hoses can become damaged which can lead to them splitting and causing a leak. Also the clamps that hold these hoses can become loosened especially if your dishwasher causes a lot of vibration.

You will need to check each hose for any signs of damage and check the clamps for any water trails. You can tighten the clamps if they are loose and replace the hose(s) if necessary.

Blocked Drain Hose

Baking Soda

If the drain hose becomes blocked with food particles, fat, grease or limescale deposits (or a combination of these), the wastewater will have nowhere to go which could lead to a leak.

If you suspect that the drain hose is clogged, you can try pouring 1 cup of bicarbonate of soda and 1 cup of distilled white vinegar into the tub and waiting for around 30 minutes. Once this mixture has had time to work, the tub should be clear of water.

If this doesn’t work you will need to disconnect the drain hose and free the clog using fast flowing running water or a plumber’s snake.

Defective Float Switch

The float switch controls the level of water in your dishwasher. If it becomes defective, it could cause the dishwasher to overfill with water and leak.

You can check this by gently lifting the float switch and listening for a click. If there is no click, the float switch will need to be replaced.

Defective Pump Or Pump Seal

The pump on a Samsung dishwasher is responsible for pumping water into, around and out of the dishwasher. Over time it can become defective especially around the gaskets or seals on the pump.

If there is a pool of water under the dishwasher, the pump is the likely cause. As the pump is difficult to access, we recommend getting a technician to investigate and replace it for you.
