Solved | How to Fix a Samsung Dishwasher Not Draining

In the hustle and bustle of modern life, we often rely on our household appliances to simplify our daily chores. One such indispensable appliance is the dishwasher.

Imagine coming home after a long day and simply placing your dirty dishes in the dishwasher, pressing a button, and voilà – sparkling clean dishes ready to be used again.

But what happens when you open your dishwasher post-cycle, expecting gleaming dishes, and instead find a pool of stagnant water at the bottom?

A dishwasher failing to drain can not only be a cause for concern regarding the appliance itself but also poses a potential health risk due to the stagnant water.

In this article, we will dive deep into the reasons why your Samsung dishwasher might not be draining and offer practical solutions to get it back in top shape.


Common Symptoms of Drainage Problems

A properly functioning dishwasher should leave your dishes spotless and the bottom of the machine empty after each cycle.

However, when drainage issues arise, certain signs and symptoms can indicate that something’s amiss.

Recognizing these symptoms early can help prevent bigger problems down the road. Here are the most common symptoms:

  1. Standing Water at the Bottom:
    • Perhaps the most obvious sign of a drainage problem is water pooled at the bottom of your dishwasher after a cleaning cycle has finished. This residual water can be a breeding ground for bacteria and mold, making it crucial to address the underlying issue promptly.
  2. Unpleasant Odors:
    • Stagnant water and accumulated food debris can produce foul smells inside the dishwasher. If you notice a persistent bad odor even after running a cycle, it could be due to drainage issues causing water to remain stagnant.
  3. Unusual Noises During the Drain Cycle:
    • Dishwashers typically make consistent sounds that you become accustomed to over time. If you start hearing unusual sounds like gurgling or humming, especially during the draining phase, it could indicate a blockage or malfunction in the draining mechanism.
  4. Dishes Not Properly Cleaned:
    • Inadequate drainage might mean that dirty water isn’t being expelled efficiently. Consequently, dishes might come out with residues, streaks, or even bits of food on them, indicating that the dishwasher isn’t draining as it should.
  5. Visible Food Debris:
    • While a few bits here and there can be normal, an excess of food debris left behind may indicate that the water isn’t draining effectively, leaving larger particles behind.
  6. Frequent Error Messages:
    • Modern Samsung dishwashers come with digital displays that can show error messages related to drainage problems. If your dishwasher frequently signals such errors, it’s a direct indication of a drainage malfunction.

By being vigilant and observing your dishwasher for these symptoms, you can address drainage issues early on, ensuring the longevity of your appliance and the cleanliness of your dishes.


Top Causes of Samsung Dishwasher Not Draining

The proper drainage of a dishwasher is crucial for its operation. If your Samsung dishwasher isn’t draining correctly, several potential culprits could be at play. Here are the most common reasons:

  1. Clogged Drain Filter:
    • What It Is: The drain filter prevents large particles of food and debris from entering the drain pump and the main drain line.
    • How It Causes Issues: Over time, food particles, debris, and grease can accumulate, clogging the filter. A blocked filter restricts water from freely flowing out of the dishwasher.
    • Solution: Regularly inspect and clean the drain filter to ensure it remains clear.
  2. Drain Hose Issues:
    • What It Is: This hose carries the wastewater from the dishwasher to the drain or garbage disposal.
    • How It Causes Issues: Kinks, bends, or clogs within the hose can impede water flow.
    • Solution: Ensure the hose is straight without any kinks. Additionally, check for obstructions within and clean it periodically.
  3. Faulty Drain Pump:
    • What It Is: A critical component, the drain pump expels water from the dishwasher.
    • How It Causes Issues: A malfunctioning or broken pump can’t move water effectively.
    • Solution: Inspect the pump for any blockages or signs of wear. If faulty, consider replacing it.
  4. Garbage Disposal Blockage:
    • What It Is: Some dishwashers connect directly to the garbage disposal system.
    • How It Causes Issues: If the disposal system is clogged or if its plug isn’t removed during installation, the dishwasher won’t drain.
    • Solution: Ensure the garbage disposal is clear and run it before using the dishwasher. If newly installed, check if the plug has been removed.
  5. Broken Check Valve:
    • What It Is: This valve ensures water flows in the right direction, preventing backflow into the dishwasher.
    • How It Causes Issues: A malfunctioning check valve can allow water to flow back into the dishwasher after draining.
    • Solution: Inspect the valve for damage or blockages, and replace if necessary.
  6. Drainage System or Sink Blockage:
    • What It Is: The main drainage system where the dishwasher connects.
    • How It Causes Issues: Blockages in the sink or main drain can cause water to back up into the dishwasher.
    • Solution: Clear any obstructions in the sink or main drainage system.
  7. Software or Control Board Issues:
    • What It Is: The “brain” of the dishwasher, controlling all its functions.
    • How It Causes Issues: Malfunctions can disrupt normal draining processes.
    • Solution: Try resetting the dishwasher. If problems persist, a technician might need to inspect or replace the control board.

Understanding these common causes can help you quickly diagnose and address drainage issues, ensuring your Samsung dishwasher operates at peak efficiency.


Tips for Preventing Drainage Issues

While dealing with a dishwasher that doesn’t drain can be frustrating, many potential issues can be preempted with regular maintenance and a few best practices.

Here are some handy tips to keep your dishwasher draining efficiently:

  1. Regular Maintenance:
    • Frequency: At least once a month, take a few moments to inspect the vital components of your dishwasher.
    • Focus on the Filter: Remove and clean the drain filter, ensuring that no food debris or buildup is blocking it.
  2. Scrape, Don’t Rinse:
    • Before placing dishes in the dishwasher, scrape off food particles. While it might be tempting to rinse dishes thoroughly, modern dishwashers are designed to handle some amount of residue. Over-rinsing can actually reduce the efficiency of certain dishwasher detergents.
  3. Check the Drain Hose:
    • Ensure the drain hose isn’t kinked or bent. Over time, hoses can shift, so periodically ensure it has a clear and unobstructed path.
  4. Use the Right Detergent:
    • Ensure you’re using a dishwasher detergent suitable for your water type (hard or soft). Some detergents can cause buildup in the machine, leading to drainage issues.
  5. Regularly Clean the Dishwasher:
    • Once every month or two, run an empty cycle with a dishwasher cleaner or a cup of white vinegar placed upright in the lower rack. This can help dissolve grease and buildup, ensuring smooth drainage.
  6. Avoid Overloading:
    • Overloading the dishwasher can lead to poor water circulation and drainage. Ensure there’s space between items and that nothing is obstructing the spray arms or drain.
  7. Inspect the Garbage Disposal:
    • If your dishwasher drains through a garbage disposal, make sure it’s working efficiently and isn’t clogged. Run it before starting the dishwasher to ensure it’s clear.
  8. Stay Updated with Software:
    • For modern Samsung dishwashers with smart features, ensure the software is up-to-date. Manufacturers might release updates that address performance or drainage issues.
  9. Seek Professional Maintenance:
    • Consider having a professional technician inspect and service your dishwasher annually. They can catch issues that might be overlooked in regular home maintenance.

By incorporating these tips into your routine, you can significantly reduce the risk of drainage problems and ensure that your dishwasher remains in excellent working condition for years to come.


When to Call a Professional

While many dishwasher issues can be diagnosed and even remedied with a little DIY know-how, there are times when professional intervention is the best – or even the only – course of action.

Recognizing when it’s time to call in the experts can save you time, money, and further complications. Here’s when it might be time to make that call:

  1. Persistent Issues:
    • If you’ve tried troubleshooting common drainage problems and your dishwasher is still not draining or consistently shows the same symptoms, it’s likely time to get professional help.
  2. Electrical Concerns:
    • If you suspect the issue is related to the dishwasher’s electronics, like the control board, it’s best not to attempt a DIY fix. Mishandling can result in further damage or even safety hazards.
  3. Leakages and Water Damage:
    • Water leaking from your dishwasher can damage your kitchen or even cause structural issues. If you notice pooling water or signs of a leak, it’s essential to consult a professional to prevent more extensive damage.
  4. Strange Noises:
    • If your dishwasher begins making unusual or loud noises that you can’t identify or remedy through basic troubleshooting, it might indicate a more severe internal problem.
  5. Installation or Setup Issues:
    • If you’ve recently moved or got a new dishwasher and it’s not draining from the get-go, it might be an installation issue. Professionals can ensure it’s set up correctly.
  6. Repeated Error Messages:
    • Modern dishwashers often display error codes on their screens when something’s amiss. If you’re frequently seeing these codes, especially after trying to fix the issue, it’s a sign that professional diagnosis is required.
  7. Comfort Level and Warranty Concerns:
    • Not everyone is comfortable tinkering with appliances. If you’re unsure, it’s always better to call a pro. Additionally, DIY fixes might void your warranty, so if your dishwasher is still under warranty, always consult professional services.
  8. Component Replacement:
    • Some parts, like the drain pump or the motor, can be challenging to replace without the right tools or expertise. If a vital component seems faulty, getting a technician to handle the replacement is advisable.
  9. Regular Maintenance:
    • Even if you’re not facing issues, it’s a good idea to have a professional technician inspect and service your dishwasher once a year or as recommended by the manufacturer. This preventive measure can catch potential issues before they become significant problems.

By recognizing when it’s time to call a professional, you ensure the longevity of your appliance, safeguard your home from potential water damage, and guarantee that your dishes are cleaned in the most efficient manner possible.

Frequently Asked Questions on Samsung Dishwasher Drainage Issues

Why is there a pool of water at the bottom of my Samsung dishwasher after a cycle?

A small amount of water is normal after a cycle to keep the seal moist. However, excessive water indicates a drainage problem. This could be due to a clogged filter, a kinked drain hose, or a faulty drain pump.

Can I clean the dishwasher filter myself?

Yes, most Samsung dishwasher models have a removable filter. It’s recommended to regularly inspect and clean it. Simply twist it out, rinse it under running water, and place it back.

My dishwasher drain hose is connected to the garbage disposal. Could this be the drainage problem?

It’s possible. If the garbage disposal is clogged or if the plug wasn’t removed during the dishwasher installation, it can prevent the dishwasher from draining. Always ensure the garbage disposal is clear and run it before using the dishwasher.

I hear a humming sound, but the dishwasher isn’t draining. What might this indicate?

A humming sound often suggests the drain pump is trying to function. It might be blocked or could be failing. You might need to inspect it for obstructions or consider replacing it.

Can software or control board issues lead to drainage problems in my Samsung dishwasher?

Yes, while mechanical issues are more common, software or control board malfunctions can disrupt the normal draining process. A reset might solve the problem, but persistent issues might require professional diagnosis.

How often should I clean my dishwasher to prevent drainage issues?

Ideally, you should clean the filter once a month and run a cleaning cycle with a dishwasher cleaner or white vinegar every 1-2 months. Regular maintenance can help prevent many common drainage problems.

I’ve tried troubleshooting, but the issue persists. When should I call a professional?

If you’ve addressed the common causes and the problem still exists, or if you’re unsure about any step, it’s advisable to call a professional technician. This ensures safety, preserves your warranty, and can prevent further damage.

Will using too much detergent cause drainage issues?

Excessive detergent can lead to soap buildup in the dishwasher, potentially causing drainage issues. Always use the recommended amount and type of detergent for your water hardness and machine specifications.
