How to Fix Whirlpool WDT730 Not Cleaning Dishes
If your Whirlpool WDT730 dishwasher isn’t cleaning your dishes effectively, you’re in the right place! This guide will help you identify common issues and provide step-by-step solutions to get your dishwasher back to its sparkling self. Let’s dive into the problem and explore possible causes and practical fixes.
Understanding Common Causes
Dishwashers, like any appliance, can encounter a variety of issues that prevent them from performing optimally. Here are some common reasons why your Whirlpool WDT730 might not be cleaning dishes as expected:
1. Poor Water Flow
Inadequate water flow during the wash cycle can lead to insufficient cleaning. This issue often stems from a clogged spray arm, a kinked or damaged water supply hose, or a malfunctioning inlet valve.
2. Dirty Filters
Over time, food particles can accumulate in the dishwasher’s filters, obstructing water flow and preventing proper cleaning. Regularly cleaning your dishwasher’s filters is essential to maintaining its efficiency.
3. Incorrect Detergent Usage
Using the wrong type of dishwashing detergent or insufficient amounts can hinder cleaning performance. Always ensure you’re using a dishwasher-safe detergent and following the manufacturer’s recommendations.
4. Faulty Heating Element
The heating element ensures your dishes get sanitized during the final rinse cycle. If it malfunctions, your dishes may appear clean but not be thoroughly sanitized.
Step-by-Step Troubleshooting and Fixes
Now that we’ve identified potential causes, let’s walk through some troubleshooting steps to resolve the issue with your Whirlpool WDT730 dishwasher:
1. Check for Clogs
- Inspect the Spray Arms: Remove the lower spray arm and clean it thoroughly to ensure no food particles are blocking water flow.
- Examine the Water Supply Hose: Look for any kinks or damage that might restrict water flow. Straighten out any kinks and replace hoses if damaged.
2. Clean the Filters
Access your dishwasher’s filters, usually located at the bottom grate or behind a removable panel. Remove and clean them with warm soapy water, rinsing thoroughly before putting them back.
3. Use Correct Detergent
Ensure you’re using a dishwasher-safe detergent suitable for your water hardness. Refer to the detergent packaging or your dishwasher’s manual for guidance.
4. Test Heating Element (Advanced)
If you suspect a faulty heating element, you might need to test it using a multimeter. For safety reasons and unless you’re comfortable with electrical work, it’s best to call a professional at this stage.
When to Call a Professional
While many dishwasher issues can be addressed with basic troubleshooting, some situations warrant calling in a professional:
- Persistent Problems: If you’ve tried the above steps and your dishwasher still doesn’t clean well, it’s probably time to consult a technician.
- Electrical Components: Working with electrical parts like the heating element or control board can be dangerous. A professional can diagnose and repair these components safely.

To maintain your Whirlpool WDT730 dishwasher in top condition, consider these preventive measures:
- Regular Cleaning: Scrape off food particles before loading and clean the filters monthly.
