If you’re like many households, your dishwasher is an essential appliance in your kitchen, making post-meal cleanup significantly easier. However, encountering issues with your dishwasher’s heat dry feature can lead to frustration, particularly when you expect your dishes to come out clean and dry. This article delves into the common reasons why the heat dry function may not be working in your Whirlpool dishwasher, and offers effective troubleshooting steps and solutions to help you get back to clean, dry dishes in no time.
Understanding the Heat Dry Feature
The heat dry feature on your Whirlpool dishwasher is designed to use heated air to thoroughly dry your dishes after the washing cycle. This enhances the drying process, reduces spotting, and ensures your dishes emerge ready to be put away straight from the machine. The functionality of this feature can be influenced by several elements, including the dishwasher’s internal components, the cycle settings, and even external factors such as water temperature.
Common Causes of Heat Dry Malfunctions
Understanding why your Whirlpool dishwasher’s heat dry feature is malfunctioning can save you time and effort when troubleshooting. Below are some of the most common reasons:
1. Improper Cycle Selection
Many dishwashers come with preset cycles that may influence drying times and methods. If you’ve selected a cycle that does not automatically incorporate the heat dry function, your dishes may not come out fully dry.
- Normal Wash: This often includes a heated dry phase.
- Quick Wash: Often skips the heat dry phase to save time and energy.
2. Faulty Heating Element
The heating element is the component responsible for warming the air inside the dishwasher during the drying cycle. If the heating element is faulty or burnt out, it won’t generate the necessary heat to dry your dishes effectively.
3. Issues with the Thermostat
The thermostat regulates the temperature within the dishwasher. A malfunction or a short circuit in this component can also lead to insufficient heating, meaning your heat dry function may not work as intended.
4. Clogged or Damaged Spray Arms
Dirty or damaged spray arms can disrupt water flow, which means dishes may not get rinsed properly—leading to drying issues. If the spray arms are clogged with food particles or mineral buildup, it’s essential to clean them to ensure they function correctly.
5. High Humidity Environment
Sometimes, the environment can also affect the effectiveness of the heat dry feature. If your kitchen is particularly humid, it may be challenging for the dishwasher to evaporate moisture from the dishes and interior, which may result in wet dishes upon completion.
Troubleshooting Steps to Fix the Heat Dry Feature
Before you call a professional or consider replacing your appliance, there are several troubleshooting steps you can take to identify and resolve the problem:
Step 1: Check the Cycle Settings
The first step is to ensure that you are using the correct cycle that includes the heat dry option. Consult your dishwasher’s manual to understand which cycle to use for optimal drying.

If the heating element appears faulty, it will likely need to be replaced.
Step 3: Test the Thermostat
To test the thermostat:
1. Locate the thermostat: Check your user manual for the exact location, usually found near the heating element.
2. Use a multimeter: Set it to continuity mode, and probe the thermostat terminals. If there is no continuity, it may need replacement.
Step 4: Clean the Spray Arms
Inspect the spray arms for clogs. Here’s how:
1. Remove them: Pull the spray arms off their mounts.
2. Clean carefully: Use warm soapy water or vinegar to clean off any debris. Ensure that all spray holes are free of clogs before reattaching.
Step 5: Monitor for Environmental Factors
If you live in a humid area, consider using your dishwasher during cooler parts of the day or running an exhaust fan to improve air circulation in the kitchen. You can also opt for drying your dishes in batches, allowing more space for moisture to escape.
When to Call a Professional
If you’ve gone through the above troubleshooting steps and your Whirlpool dishwasher still isn’t drying properly, it may be time to consult a professional. Some issues, like electrical failures or complex internal faults, require expertise that can best be provided by a qualified technician.
