Samsung Dishwasher Not Drying Dishes? Here’s What to Check

Is your Samsung dishwasher not drying dishes the way it should? You’re not alone. This is one of the most common problems Samsung dishwasher owners face, especially after installing a new unit or switching to a more energy-efficient model. Whether your dishes come out dripping wet or just a little damp and spotty, there are several reasons this could be happening. Some are simple user errors, while others require a deeper look at your dishwasher’s components and maintenance habits.

Why Is My Samsung Dishwasher Not Drying Dishes?

When your Samsung dishwasher isn’t drying dishes properly, it can be frustrating and inconvenient. The whole point of using a dishwasher is to avoid towel-drying every cup and utensil afterward. The good news? Most drying issues can be solved without calling a technician if you know what to check. Below, we’ll walk you through the most common reasons your dishwasher might leave your dishes wet, starting with the easiest to fix and ending with the more advanced technical issues.

Rinse Aid Not Used or Set Too Low

Samsung dishwashers are designed to work in tandem with rinse aid to reduce water spots and boost drying performance. Rinse aid lowers the surface tension of water, helping it slide off your dishes rather than clinging to them and evaporating slowly.

If the rinse aid dispenser is empty or set too low, it’s likely your dishes will come out damp or covered in droplets. This is especially true in homes with hard water or high humidity.

What to do:

• Open the rinse aid compartment (usually on the inside of the door) and fill it up completely.
• Set the dispenser to level 2 or 3, depending on your local water conditions. Many Samsung models let you adjust this manually.
• If you already use rinse aid and still have drying problems, try increasing the setting by one level.

This one small change can often solve the issue completely, especially if you’re noticing water spots on glassware or if plastics feel particularly wet after a cycle.

Incorrect Cycle or Drying Option Selected

Believe it or not, your drying problem may come down to which wash cycle you’re using. Not all cycles are created equal. Many Samsung models include energy-saving cycles like “Eco” or “Express” that either shorten or skip the drying phase to save power.

Using one of these cycles can result in dishes that are clean but wet when the cycle ends.

How to fix it:

• Choose a full-cycle option like “Auto,” “Normal,” or “Heavy” instead of a quick or energy-saving mode.
• Make sure to manually enable the “Heated Dry,” “Sanitize,” or “Extra Dry” settings if your model offers them. These options activate higher temperatures that help water evaporate more quickly.

You can usually find these settings on the control panel, or in your model’s app if it’s a smart dishwasher.

Dishes Are Loaded Improperly

The way you load your dishwasher matters more than you might think. If dishes are stacked too closely or block the air vents, steam won’t be able to escape and airflow will be restricted, both of which are critical to the drying process.

Common loading mistakes:

• Bowls and plates are nested together, creating water-trapping pockets.
• Tall items are placed in front of the vent or fan assembly, blocking airflow.
• Plastic containers are placed on the bottom rack, where they receive less air circulation and heat.

Best practices for loading:

• Always place plastics and lightweight items on the top rack.
• Face bowls and cups downward so water can drain off.
• Avoid overloading. Leave enough space between items so air can move freely.

These small changes can drastically improve your dishwasher’s ability to dry dishes effectively.

Plastic Items Stay Wet No Matter What

Even in a properly functioning Samsung dishwasher, plastic dishes are notoriously difficult to dry. That’s because plastic doesn’t retain heat the way glass, metal, or ceramic does. The heat helps water evaporate, so without it, moisture sticks around longer.

Tips to reduce wet plastics:

• Use the “Extra Dry” or “Sanitize” setting if available.
• Avoid washing plastic containers on cycles without heated drying.
• Unload the bottom rack first. This prevents any lingering water from upper-rack plastics from dripping onto the lower dishes.

If your dishwasher has a condensation drying system (common in Samsung models), plastics are often the last items to dry, so they may always need a quick towel-off.

Dirty Filter or Clogged Spray Arms

Cleaning performance and drying performance go hand-in-hand. If your dishwasher filter is clogged with food debris or the spray arms aren’t spinning freely, dishes may not be properly rinsed. This leads to lingering moisture, foul dishwasher odors, and poor drying results.

How to clean:

1. Remove the bottom rack and take out the filter.
2. Rinse the filter under warm water and gently scrub with a soft brush if needed.
3. Inspect the spray arms for mineral buildup or stuck food particles. Use a toothpick to clear any clogged spray holes.

Keeping these parts clean ensures that your dishwasher functions efficiently and reduces the amount of moisture left behind at the end of a cycle.

Hard Water Mineral Buildup

Hard water can wreak havoc on dishwashers. Over time, mineral deposits build up on the heating elements, sensors, and even the interior walls, which affects both cleaning and drying.

Signs you have hard water issues:

• Cloudy glassware after a wash
• White, chalky film inside the dishwasher
• Poor drying, especially on the top rack

How to solve it:

• Use a dishwasher cleaner with citric acid once a month to remove buildup.
• Consider adding a water softener to your plumbing system or using dishwasher additives designed for hard water.

Even if everything else is working perfectly, hard water can reduce the effectiveness of every cycle.

AutoRelease™ Door Feature Not Working

Many Samsung dishwashers include a feature called AutoRelease™, which automatically opens the door at the end of the cycle to let out steam and introduce airflow for better drying. If this door doesn’t open, the interior stays steamy and dishes remain wet.

Troubleshooting tips:

• Make sure nothing is blocking the door from opening, like a cabinet handle or rug.
• Check your dishwasher settings. AutoRelease™ may be turned off by default or disabled in child lock mode.
• If the feature still won’t engage, the door latch mechanism or internal motor may need service.

This feature is especially important for plastic-heavy loads, which benefit most from added ventilation.

Water Temperature Too Low

Dishwashers rely on hot water to both clean and dry effectively. If the incoming water temperature is too low, it can lead to poor performance across the board.

Check your hot water:

• Run your kitchen faucet until the water gets hot.
• Use a thermometer to measure the temperature. It should be at least 120°F (49°C).
• If it’s lower, increase the temperature on your water heater or delay starting the dishwasher until after other hot water appliances have finished running.

Hot water is critical to both washing and evaporating moisture. Without it, even heated drying settings may fall short.

Vent or Fan Assembly Failure

Some Samsung models rely on a vent system and fan to circulate air and remove steam during the drying phase. If the fan fails or the vent is stuck closed, humid air stays trapped inside.

How to recognize this problem:

• Steam pours out when you open the door after the cycle finishes.
• The interior feels muggy and warm instead of dry.
• You don’t hear the fan running during drying.

This typically requires professional service, as the fan motor or vent mechanism may need to be replaced.

Defective Heating Element

Not all Samsung dishwashers include a traditional exposed heating element. Some use a hidden one to help dry dishes, especially during sanitize or extra dry cycles. If the heating element is damaged or not functioning, the dishwasher won’t generate the necessary heat to evaporate water.

What to look for:

• Dishes feel cold and wet after the cycle, even with “Heated Dry” selected.
• The sanitize cycle doesn’t reach high temperatures.

This component requires testing with a multimeter and professional replacement if found to be faulty.

Faulty Temperature Sensor or Thermistor

The thermistor monitors internal temperature. If it reads incorrectly, the dishwasher might assume it has reached drying temperature and prematurely end the drying cycle, or skip it entirely.

Symptoms of a faulty thermistor:

• Random drying failures despite proper settings.
• Error codes on the display panel.

Because thermistors are internal components, testing and replacing them is best left to a qualified technician.

Control Board Failure

The control board governs the entire dishwasher cycle, including the drying phase. If it malfunctions, the machine may skip steps, select the wrong cycle logic, or fail to activate heating or fan components.

Signs of a faulty control board:

• Intermittent drying performance
• Unresponsive buttons or error messages
• Cycle finishes too early or skips drying entirely

Resetting the dishwasher by turning off the power at the breaker for one minute may temporarily resolve some issues, but persistent problems often require a control board replacement.
