Why Is My Whirlpool Dishwasher Not Drying? Unveiling the Culprits Behind Soggy Dishes
Your Whirlpool dishwasher isn’t drying because several common issues can hinder the drying cycle’s effectiveness. Addressing problems with the drying aid dispenser, heating element, ventilation, or loading techniques will usually resolve the problem.
Introduction: The Perpetual Puddle and the Pursuit of Dry Dishes
Few things are more frustrating than unloading a dishwasher full of clean, yet soaking wet, dishes. You’ve invested in a Whirlpool dishwasher for its reliability and convenience, but finding everything covered in droplets after a cycle can quickly turn into a daily annoyance. Fortunately, this problem is often caused by easily identifiable and rectifiable issues. This article will delve into the common culprits behind a Whirlpool dishwasher’s drying failures, offering practical solutions to help you achieve sparkling, dry results every time.
Understanding the Whirlpool Dishwasher Drying Process
Most Whirlpool dishwashers utilize a condensation drying system, sometimes augmented by a heating element. This means that the dishes are rinsed with hot water, causing them to retain heat. As the hot, moist air inside the dishwasher cools, the moisture condenses on the cooler stainless steel interior of the dishwasher tub and drains away. Older models and some higher-end models may also use a heating element to assist in drying. Knowing which type your dishwasher utilizes is crucial for troubleshooting.
Factors Affecting Drying Performance
Several factors influence how well your Whirlpool dishwasher dries your dishes. These include:
- Water Temperature: The final rinse water needs to be hot enough for effective evaporation.
- Drying Aid Dispenser: Drying aids (like Rinse Aid) lower the surface tension of the water, allowing it to sheet off the dishes.
- Heating Element: (If equipped) A functioning heating element provides supplemental heat for faster evaporation.
- Ventilation: Proper ventilation allows moist air to escape the dishwasher.
- Loading Techniques: Overcrowding the dishwasher blocks airflow and prevents proper drying.
- Dish Type: Plastics tend to retain less heat than glass or ceramic, making them harder to dry.
- Water Hardness: Hard water can leave mineral deposits that hinder drying.
Diagnosing the Issue: A Step-by-Step Approach
Before calling a repair technician, consider the following steps to diagnose the drying problem:
- Check the Drying Aid Dispenser: Ensure the dispenser is filled with a quality drying aid and that the dispenser is set to an appropriate level. Increase the setting if dishes are consistently wet.
- Inspect the Heating Element (If Equipped): Visually inspect the heating element for any signs of damage, such as blistering or breaks. A multimeter can be used to test its continuity (refer to your dishwasher’s service manual for instructions). Caution: Disconnect power before inspecting or testing the heating element.
- Examine the Vent: Make sure the vent (usually located on the door) is not blocked or obstructed. Some models have a fan-assisted vent, check if the fan is spinning freely.
- Review Your Loading Technique: Avoid overcrowding and ensure dishes are spaced properly to allow for adequate airflow. Place plastics on the top rack.
- Assess Water Temperature: Confirm your water heater is set to at least 120°F (49°C).
- Run a Test Cycle: Run the dishwasher on its hottest cycle with a drying aid. Observe the drying performance closely.
Common Mistakes That Hinder Drying
Even with a well-functioning dishwasher, certain practices can sabotage the drying process:
- Skipping Drying Aid: Drying aid is essential for proper drying, especially in condensation drying systems.
- Using Old or Expired Drying Aid: Over time, drying aid can lose its effectiveness.
- Opening the Dishwasher Too Soon: Allow the dishwasher to complete the entire drying cycle.
- Overloading the Dishwasher: This restricts airflow and prevents even drying.
- Using the Wrong Detergent: Some detergents are less effective at promoting drying.
- Neglecting Regular Maintenance: Cleaning the filter and spray arms helps maintain optimal performance.
Solutions and Preventative Measures
Once you’ve identified the potential cause, implement the following solutions:
- Refill the Drying Aid Dispenser: Use a high-quality rinse aid and adjust the dosage as needed.
- Replace the Heating Element (If Faulty): A damaged heating element must be replaced by a qualified technician.
- Clear the Vent: Ensure proper ventilation by removing any obstructions.
- Improve Loading Techniques: Space dishes properly to allow for optimal airflow.
- Increase Water Heater Temperature: Set your water heater to at least 120°F (49°C).
- Run a Maintenance Cycle: Use a dishwasher cleaner regularly to remove mineral deposits and food debris.

Frequently Asked Questions (FAQs)
Why are my plastics always wet, even when everything else is dry?
Plastics have a lower heat retention capacity than glass or ceramic. This means they cool down more quickly and don’t facilitate condensation as effectively. To improve drying, place plastics on the top rack, which is generally hotter. You might also consider hand-drying plastics or selecting dishwasher models that have specialized drying cycles for plastics.
How do I know if my heating element is working?
Visually inspect the element for any visible breaks or blistering. If you have a multimeter, you can test the element for continuity. A reading of 0 ohms or very low resistance indicates a working element. Always disconnect the power supply before attempting any electrical testing. If you’re not comfortable with electrical testing, contact a qualified technician.
What is rinse aid, and how does it help with drying?
Rinse aid is a surfactant that reduces the surface tension of water. This allows the water to sheet off the dishes instead of forming droplets. This significantly reduces spotting and improves drying performance, especially on glass and plastic.
My dishwasher has a fan-assisted drying system. How can I tell if the fan is working?
During the drying cycle, listen carefully for the sound of the fan operating. You can also open the dishwasher door (carefully, after the washing and initial rinse cycles, observing safety precautions) and visually inspect the fan to see if it’s spinning. If the fan is not working, it may need to be replaced by a qualified technician.
Is it normal for the inside of my dishwasher to be wet after a cycle?
Yes, it’s normal for the inside of the dishwasher tub to be slightly damp after a cycle, especially with condensation drying systems. The goal is for the dishes to be dry, not the inside of the dishwasher itself. However, excessive water pooling at the bottom of the tub may indicate a drainage problem.
Can hard water affect my dishwasher’s drying performance?
Yes, hard water can leave mineral deposits on dishes and inside the dishwasher, which can interfere with drying. Consider using a dishwasher cleaner regularly to remove these deposits. A water softener can also help mitigate the effects of hard water.
I’m using rinse aid, but my dishes are still wet. What should I do?
First, ensure the rinse aid dispenser is full and set to an appropriate level. Try increasing the setting gradually until you achieve the desired drying results. Also, make sure you are using a high-quality rinse aid. If the problem persists, check other potential causes, such as heating element issues or improper loading.
What’s the best way to load my dishwasher for optimal drying?
Avoid overcrowding the dishwasher. Place dishes so that water can reach all surfaces. Place plastics on the top rack. Avoid nesting dishes or blocking spray arms. Refer to your dishwasher’s manual for specific loading recommendations.
Should I open the dishwasher door immediately after the cycle is finished?
It’s generally best to wait a few minutes after the cycle ends before opening the dishwasher. This allows the remaining moisture to evaporate and the dishes to cool down. Cracking the door open slightly can help release steam and improve drying.
My dishwasher has a “sanitize” option. Does this help with drying?
The “sanitize” option uses a higher water temperature, which can improve drying performance. However, it also increases energy consumption. Use this option judiciously.
How often should I clean my dishwasher’s filter?
You should clean your dishwasher’s filter at least once a month, or more frequently if you notice food debris accumulating. A clogged filter can reduce washing and drying performance.
Is it possible to add a heating element to a dishwasher that doesn’t have one?
Generally, it is not recommended to add a heating element to a dishwasher that wasn’t originally designed with one. Doing so could void the warranty and potentially damage the appliance. Dishwashers without heating elements rely solely on condensation drying.
