How to Fix Whirlpool WDT730 Leaving White Film
If your Whirlpool WDT730 dishwasher is leaving a white film on your dishes after the cycle, it’s an issue you’ll want to address quickly. This problem isn’t just unsightly; it can indicate that there’s an underlying issue affecting the cleanliness and potentially the lifespan of your appliance. Let’s explore the common causes, step-by-step solutions, when professional help is needed, and how to prevent this problem in the future.
Understanding the Problem
A white film on dishes after a Whirlpool WDT730 dishwasher cycle usually signifies hard water buildup or residue from detergent, food particles, or sometimes even issues with the dishwasher’s internal components.
Common Causes
- Hard Water: Mineral-rich water can leave behind deposits when heated.
- Insufficient Detergent or the Wrong Type: Using too little or a detergent not designed for hard water can lead to incomplete cleaning.
- Food Particles or Residue: Leftover food on dishes can cause bacterial growth and result in white residue.
- Clogged Spray Arms: Food particles trapped in the spray arm holes can restrict water flow and lead to poor cleaning.
Step-by-Step Fix Instructions
- Check Water Hardness: If you suspect hard water, consider using a water softener or a dishwasher-specific detergent designed to combat mineral buildup.
- Adjust Detergent Usage: Ensure you’re using the correct amount of dishwasher detergent. Follow the manufacturer’s recommendations on the detergent packaging.
- Clean Spray Arms:
- Unscrew and remove the top and bottom spray arms.
- Thoroughly clean them under running water, removing any food particles or mineral deposits.
- Ensure they fit back correctly and are securely fastened.
- Run a Cleaning Cycle: Use an affresh® Dishwasher Cleaner tablet or follow the manufacturer’s instructions for a cleaning cycle designed to remove residue and buildup from your dishwasher’s interior.
- Inspect Filters:
- Access your dishwasher’s filter, usually located at the bottom front grate or under the spray arm.
- Clean it to ensure no blockages affect water flow.
When to Call a Professional
If you’ve tried these steps and your dishes still have a white film, there might be more serious issues at play. These could include malfunctioning heating elements, faulty pumps, or internal component problems. In such cases, it’s best to call a qualified appliance repair technician.
Prevention Tips
- Regular Cleaning: Run your dishwasher’s cleaning cycle regularly to prevent buildup and maintain efficiency.
- Pre-Rinse Dishes: Scrape off excess food from dishes before loading the dishwasher to reduce chances of clogging.
- Use a Water Softener (if needed): If hard water is a persistent issue, consider installing a water softening system for your home.
- Check and Clean Filters Regularly: Make it a habit to inspect and clean dishwasher filters every month or as recommended by the manufacturer.
Frequently Asked Questions (FAQ)

A: It’s recommended to check and clean the filter monthly or as advised by your dishwasher manual.
