Dishwasher Won’t Dry: Troubleshooting and Fixing Issues


Having a dishwasher that effectively dries your dishes is an essential part of the appliance’s functionality. After all, what good is a dishwasher if you have to spend extra time drying your dishes by hand? Unfortunately, many people experience issues with their dishwasher’s drying performance, such as dishes coming out wet or with water spots. These issues can be frustrating and time-consuming to deal with. In this article, we will explore the different causes of dishwasher drying problems and provide tips and solutions to help you improve your dishwasher’s drying performance.

When dishes come out of the dishwasher wet or with water spots, it can be due to a variety of factors. One common cause is the type of drying method used by the dishwasher.

Understanding the Drying Cycle of a Dishwasher


To understand why dishes may not be drying properly in your dishwasher, it’s important to have a basic understanding of how the drying cycle works. Most dishwashers have two main types of drying methods: heating element drying and condensation drying.

Heating element drying involves using a heating element located at the bottom of the dishwasher to heat the air inside. As the hot air circulates, it evaporates the moisture on the dishes, leaving them dry. This method is typically more effective at drying dishes quickly but may use more energy.

Condensation drying, on the other hand, relies on the natural process of condensation to dry the dishes. During this cycle, the dishwasher heats up the water inside to a high temperature. When the cycle is complete, the hot water is drained, and cool air is circulated inside the dishwasher. As the hot dishes come into contact with the cool air, condensation occurs, and the moisture is removed from the dishes. This method is generally more energy-efficient but may take longer to dry the dishes completely.

Common Causes of Dishwasher Drying Problems


There are several common issues that can cause a dishwasher to not dry properly. One of the most common causes is a faulty heating element. If the heating element is not working correctly, it will not generate enough heat to effectively dry the dishes. Another common issue is clogged vents. The vents in a dishwasher allow hot air to escape during the drying cycle. If these vents become clogged with debris or food particles, it can restrict airflow and prevent proper drying.

A malfunctioning fan motor can also contribute to poor drying performance. The fan motor helps circulate the hot air inside the dishwasher during the drying cycle. If the fan motor is not functioning correctly, it may not be able to distribute the hot air evenly, resulting in wet dishes.

Other potential causes of dishwasher drying problems include a faulty thermostat, which regulates the temperature inside the dishwasher, and issues with the dishwasher’s drain hose or filter. A clogged drain hose or filter can prevent proper drainage of water, leading to excess moisture in the dishwasher and on the dishes.

How to Diagnose a Dishwasher That Won’t Dry


If you’re experiencing issues with your dishwasher’s drying performance, there are several steps you can take to diagnose the problem. First, check if there are any visible signs of damage or malfunction, such as a broken heating element or a clogged vent. If everything appears to be in working order, try running a diagnostic cycle on your dishwasher if it has one. This cycle will test all of the dishwasher’s components and sensors to identify any potential issues.

If your dishwasher does not have a diagnostic cycle, you can manually test the heating element, thermostat, and fan motor. To test the heating element, you will need a multimeter. Disconnect the dishwasher from the power source and locate the heating element. Use the multimeter to test for continuity. If there is no continuity, the heating element is faulty and needs to be replaced.

To test the thermostat, you will also need a multimeter. Disconnect the dishwasher from the power source and locate the thermostat. Set your multimeter to the ohms setting and touch the probes to the terminals on the thermostat. If there is no continuity, the thermostat is faulty and needs to be replaced.

To test the fan motor, you will need to access it by removing the dishwasher’s front panel. Disconnect the dishwasher from the power source and locate the fan motor. Use a multimeter to test for continuity. If there is no continuity, the fan motor is faulty and needs to be replaced.

Tips for Maintaining a Dishwasher’s Drying Performance


Routine maintenance is essential for keeping your dishwasher’s drying performance at its best. One of the most important maintenance tasks is cleaning the dishwasher’s filter. The filter traps food particles and debris, preventing them from clogging the drain hose or affecting the dishwasher’s performance. Regularly removing and cleaning the filter will help ensure proper drainage and prevent clogs.

Another maintenance task that can improve drying performance is checking for clogs in the drain hose. Over time, debris can accumulate in the drain hose, restricting water flow and causing excess moisture in the dishwasher. To check for clogs, disconnect the dishwasher from the power source and remove the drain hose. Inspect it for any obstructions and clean it if necessary.

Additionally, using a rinse aid can help improve drying performance by reducing water spots and promoting faster drying. Rinse aids contain surfactants that help water sheet off dishes, preventing droplets from forming and leaving behind spots. Adding a rinse aid to your dishwasher’s dispenser can significantly improve drying results.

How to Clean the Dishwasher’s Heating Element





If you have determined that a dirty or malfunctioning heating element is causing your dishwasher’s drying problems, cleaning it may help improve its performance. To clean the heating element, start by disconnecting the dishwasher from the power source. Locate the heating element, which is usually located at the bottom of the dishwasher.

Using a soft brush or cloth, gently scrub the heating element to remove any built-up residue or debris. Be careful not to use any abrasive materials that could damage the heating element. Once you have cleaned the heating element, reconnect the dishwasher to the power source and run a cycle to see if the drying performance has improved.

Checking and Replacing the Dishwasher’s Thermostat


The thermostat plays a crucial role in regulating the temperature inside the dishwasher during the drying cycle. If you suspect that a faulty thermostat is causing your dishwasher’s drying problems, you can check it using a multimeter. Start by disconnecting the dishwasher from the power source and locating the thermostat.

Set your multimeter to the ohms setting and touch the probes to the terminals on the thermostat. If there is no continuity, it means that the thermostat is faulty and needs to be replaced. To replace the thermostat, disconnect any wires connected to it and remove it from its mounting bracket. Install the new thermostat and reconnect any wires.

Fixing Dishwasher Drying Problems Caused by Clogged Vents


Clogged vents can significantly impact a dishwasher’s drying performance by restricting airflow during the drying cycle. To fix this issue, start by disconnecting the dishwasher from the power source and removing any dishes or utensils from inside.

Next, locate the vents on your dishwasher. They are usually located on top of or at the back of the dishwasher. Use a soft brush or cloth to remove any debris or food particles from the vents. Be careful not to push any debris further into the vents.

Once you have cleaned the vents, reconnect the dishwasher to the power source and run a cycle to see if the drying performance has improved. If the vents were severely clogged, it may take a few cycles for the drying performance to return to normal.

How to Test and Replace a Faulty Dishwasher Fan Motor


The fan motor is responsible for circulating hot air inside the dishwasher during the drying cycle. If you suspect that a faulty fan motor is causing your dishwasher’s drying problems, you can test it using a multimeter. Start by disconnecting the dishwasher from the power source and removing the front panel to access the fan motor.

Locate the fan motor and disconnect any wires connected to it. Set your multimeter to the ohms setting and touch the probes to the terminals on the fan motor. If there is no continuity, it means that the fan motor is faulty and needs to be replaced.
