Samsung Dishwasher Not Draining: 6 Methods To Fix

With their sleek design and superior functionality, Samsung dishwashers have become a popular choice for many households. However, like all appliances, they can sometimes experience issues.

In this article, we will give you a detailed guide to solving your problem. Additionally, we will offer some tips to help you fix them.

Understanding Your Samsung Dishwasher

Samsung dishwashers feature a contemporary design that easily fits into any kitchen. They spray hot water and detergent on the dishes, rinse them, and then dry them. The water and food residues are drained into a hose connected to your home’s plumbing system.

While these dishwashers are generally reliable, they can encounter issues like other appliances. Not draining, not filling with water, or turning on are common problems you might face.


Common Causes

Here, we give you several reasons that could cause your Samsung dishwasher not to drain:

Clogged drain hose

A clogged drain hose is one of the most common reasons for a Samsung dishwasher not draining. Over time, bits of food, grease, and other debris can build up in the hose. This accumulation can eventually form a blockage that prevents water from draining out of the dishwasher.

Malfunctioning drain pump

The drain pump in your Samsung dishwasher is very important because it helps to get the water out of the machine and into the drain hose. If this part isn’t working right or is broken, your dishwasher might not drain as it should.

Also, if the impeller (a part inside the pump) is broken or if the motor isn’t working, your drain pump might not work properly. Sometimes, little things like pieces of broken glass or dish fragments can get stuck in the pump, making it harder for it to work correctly.

Faulty drain solenoid

The drain solenoid is another key part of your Samsung dishwasher’s drain system. This piece is a special kind of device that helps open the drain valve, letting water leave the dishwasher.

Normally, the control board sends a message to the drain solenoid. When the solenoid gets this message, it springs into action and pulls a device (like a plunger) to open the drain valve. But, if something’s wrong with the solenoid, it might not pull the plunger, the valve stays shut, and water doesn’t drain from the dishwasher.

Samsung Dishwasher Not Draining: Detailed Guide

Before seeking professional help, you can try a few troubleshooting steps:

Identify that the dishwasher is causing the issue

First, it’s a good idea to ensure the problem is true with your dishwasher and not with your home’s plumbing. A simple way to do this is by checking other water-using appliances in your house. Are they also facing drainage issues? If yes, then the problem may not be with your dishwasher after all. It could be a more broad issue with your house’s plumbing system, which might require a professional to fix.

Check for a blocked or kinked drain hose

Next, should check out your drain hose. This hose is important as it’s the path for water to leave your dishwasher. If something is blocking or twisting this hose, it can prevent the water from exiting properly.

So, if you see a blockage in the hose, you should try to remove it. You could use something like a long, bendable brush to do this. If the hose is twisted, you’ll need to straighten it. But be gentle – using too much strength could harm the hose.

Check out your drain hose

Clean your drain hose, filter, sump, and tub

Over time, small bits of food and grease can build up in different parts of your dishwasher, including the drain hose, filter, sump (the part where water collects before being pumped out), and even the tub itself. This buildup can cause drainage problems.

So, try removing these parts (refer to your dishwasher’s manual for instructions), and clean them thoroughly. Use warm, soapy water and a soft brush, then rinse well and dry before reinstalling them. This simple step could solve your drainage problem. If not, it’s time to continue troubleshooting.

Inspecting your drain pump

Additionally, the drain pump is an important part of your dishwasher’s draining mechanism. If it’s not operating as it should, your dishwasher might not be able to drain correctly.

In detail, to inspect it, you’ll first need to unplug the dishwasher and remove the toe-kick panel. Once you’ve done this, you can find the drain pump located near the front of the base. Check if it’s physically damaged or obstructed by any debris. If there’s debris, clear it out and then run the dishwasher again to see if it’s draining correctly. If there’s damage or if cleaning it out doesn’t resolve the issue, the drain pump might need to be replaced.

Check the check valve

Next is the check valve, also known as the flapper, which is a one-way valve that allows water to flow out of the dishwasher but prevents it from flowing back in. If this part is malfunctioning, it might be causing your dishwasher not to drain.

To inspect the check valve, you’ll first need to access it. It’s usually located near the back of the dishwasher, attached to the drain hose. Once you’ve found it, check if it’s able to move freely. If it’s stuck or if it’s damaged, it might need to be replaced.

Assessing your drain solenoid

Moreover, we continue to check the drain solenoid. This is an electromechanical device that opens the drain valve, allowing water to exit the dishwasher. If it’s not functioning correctly, your dishwasher might not be draining as it should.

To assess your drain solenoid, you’ll first need to locate it. It’s typically situated near the front of the dishwasher’s base, close to the drain pump. Once you’ve found it, check if it’s able to move freely. If it’s stuck or if it’s not reacting, it might need to be replaced.

Preventive Measures

Here, we give some tips to prevent your dishwasher not draining:

Regular cleaning

Keeping a routine cleaning schedule for your dishwasher is really important. Over time, things like grease, soap leftovers, and bits of food can start to build up in your dishwasher. If left unchecked, these can cause blockages and other problems.

So, you should set a schedule to deep-clean at least once a month. This should involve cleaning the interior walls, racks, and spinning arms, as well as the filter and drain hose. Moreover, there are commercial dishwasher cleaners available that can make this process easier.

Regular cleaning of your dishwasher

Check your drain hose and filter

The drain hose and filter, in particular, are prone to clogs. Regularly check and clean these parts to ensure they’re not obstructed. A flexible brush can help dislodge any buildup within the drain hose.

Scrape off food residues

While it might seem convenient to just place dishes straight into the dishwasher, doing so can increase the risk of clogs. Over time, food residues can build up within the dishwasher. To prevent this, it’s good practice to scrape off food residues from dishes before loading them into the dishwasher.

Proper loading

Overloading the dishwasher or loading dishes improperly can also lead to drainage problems, as it can prevent water from reaching all the dishes and then draining properly. Follow the manufacturer’s guide for loading dishes to ensure efficient cleaning and draining.

Regular inspections

Regularly check the different parts of your dishwasher, especially those involved in draining. This includes the drain pump, drain solenoid, and check valve. Catching and addressing issues early can prevent more serious problems down the line.

How often should I clean my Samsung dishwasher?

It’s recommended to clean your Samsung dishwasher once a month to ensure optimal performance. Regular cleaning can help prevent the buildup of food debris and grease, which can lead to draining issues.

Can I replace the drain pump myself?

If you’re handy with appliances, you might be able to replace your drain pump yourself. However, it’s important to make sure you have the correct part and understand the replacement process. If you’re unsure, it’s always best to hire a professional.
