Samsung Dishwasher - Appliance is leaking

Once the dishwasher shows visible signs of a leak, or if an error code or blinking lights appear, turn the dishwasher off at the circuit breaker. Many dishwasher leaks come from installation issues, such as the drain hose, water supply hose, leveling, or incorrectly stretching the sides of the tub when screwing it into the cabinets on either side. Reinstallation is typically all that's needed to prevent those kinds of leaks.

Note: The provided information refers to dishwashers sold in Canada. The available settings and options may differ for appliances sold in other countries.

Step #1: Run a cycle to help find the source of the leak

The fastest way to find the source of the leak is to look and feel for moisture, but the moisture will only be there right after a leak occurs. Remember to turn the dishwasher off at the circuit breaker as soon as you confirm visible signs of a leak or the dishwasher displays an error.

Note: If the leak is definitely coming from the door, you can skip to step 4. If the leak is definitely not coming from the door, only steps 2 and 3 are needed. If you're not sure, then do all the steps.

Step #2: Inspect the water supply hose

When inspecting, look and feel for moisture, damage, loose connections, or gaps between the assembled parts. Make sure to inspect where the hose connects to the dishwasher, where the hose connects to your home, and the entire length of the hose.

The water supply hose is sold separately and not covered by service. If it's the source of the leak, chances are you can reinstall it to seal up any gaps or loose connections. If that doesn't work, you can just replace the hose. We recommend a 9,925 mm (3/8") stainless steel hose, since plastic hoses are more prone to leaks. You can buy a new hose from a local hardware store.

Inspect the water supply hose

Once you have a good water supply hose, or to try to reinstall the old one, refer to the installation guide or a professional installer.

Step #3: Inspect the drain hose as well

Although the drain hose is part of the dishwasher, if it's not connected to the home properly, that's not an issue with the dishwasher, and is not covered by service. So if the drain hose's connection to the home is where the leak is coming from, all you need to do is install the drain hose correctly. This might be as simple as tightening the connection. Instructions are in the installation guide provided with your dishwasher. For leaks anywhere else along the drain hose, visit our Support Center to request service.

Step #4: Inspect the rubber seal

Sometimes the rubber seal can get pushed out of alignment. If this happens, just push it back into the channel.

It's also important that the seal is very clean. Any foreign material on the seal could potentially create a gap big enough for water to leak out. A towel with mild soap is a good way to clean it off.

Note: If the rubber seal is damaged, visit our Support Center to request service.

Step #5: Only use dishwasher detergent, not dish soap

If you notice an excessive amount of suds when you open the door, you may be using the wrong kind of detergent. Pay close attention to the type of detergent on the label: dishwasher detergent is made for dishwashers, and dishwashing liquid (or dish soap) is intended for handwashing. Using dish soap or dishwashing liquid in a dishwasher will create excessive amounts of suds that can escape the dishwasher and cause leaks. This also reduces cleaning performance and can leave soapy residue behind on your dishes and dishwasher that you'll then have to wash off.

Only use dishwasher detergent, not dish soap

If you're not sure, read the entire label and look for the word dishwasher specifically (that ends with "-er"). If it's for dishwashers, it will say so. If it doesn't say it's for dishwashers, then it's not.

Step #6: Level your dishwasher

If the dishwasher is not level left to right, the door could be bumping the cabinets on either side, preventing it from closing completely. If the dishwasher is not level front to back, and especially if the front is lower than the back, water will pool up at the door and potentially leak out. Level the dishwasher to prevent any of this from happening.

Step #7: Verify the sides of the tub are not bowed or stretched

If the cabinet screws are over-tightened, it will stretch the sides of the dishwasher, causing gaps that can leak. Measure across the opening exactly where the screws are. It should measure exactly 55,88 cm (22 inch). If it measures more than that, loosen the cabinet screws until the issue is corrected.

Step #8: Inspect the water nozzles

If there's food stuck in the nozzles (or the jets or anywhere that water sprays out of), the food may be diverting the spray of water to spray straight at the door with enough force to push it through the seal, causing a leak. Make sure all the nozzles and jets are clean.

Note: If your unit is a Waterwall model, make sure that no dishes or utensils are obstructing the movement of the water reflector.
