Kitchenaid Dishwasher Leaving White Film: Causes and Solutions
A white film on your dishes after running them through the Kitchenaid dishwasher can be frustrating.
Understanding the Problem
The white film on your dishes usually indicates hard water spots or mineral deposits. These occur when there’s an excess of minerals like calcium and magnesium in your water supply, which precipitate out during the heating process in your dishwasher.
Common Causes
1. Hard Water
Hard water is the most common culprit behind white film on dishes. If your area has naturally hard water, minerals in the water can leave residue on your dishes even after washing.
2. Incorrect Rinse Aid
Rinse aid helps to reduce spotting and filming by minimizing water spotting on dishes. If you’re not using the correct amount or type of rinse aid, it might contribute to the white film issue.
3. Insufficient Heating
Dishwashers rely on hot water to effectively clean and dry dishes. If your dishwasher isn’t heating the water sufficiently, mineral deposits may not be fully rinsed away.
4. Dirty Filters
Clogged or dirty filters can prevent proper water flow and reduce the cleaning efficiency of your dishwasher, leading to less thorough washing and more mineral buildup.
Step-by-Step Fix Instructions
1. Check Your Water Hardness
If you suspect hard water is the issue, contact your local water authority or use a home testing kit to determine the hardness level of your water supply.
2. Adjust Rinse Aid Usage
Ensure you’re using the correct type and amount of rinse aid as per the Kitchenaid dishwasher manual. Refill or replace the rinse aid dispenser if necessary.
3. Clean Filters Regularly
Remove and clean your dishwasher’s filters every 1-2 months, following the manufacturer’s instructions. This will help maintain optimal water flow and cleaning efficiency.
4. Run a Cleaning Cycle
Perform a cleaning cycle with a Kitchenaid dishwasher cleaner or use white vinegar (1 cup) in an empty dishwasher on a high-temperature setting to help dissolve mineral deposits.
5. Heat Element Check
If you suspect insufficient heating, consult your Kitchenaid dishwasher manual or contact customer support for troubleshooting steps specific to your model regarding the heating element.
When to Call a Professional
If you’ve tried these solutions and the white film persists, it might indicate a more serious issue such as a faulty heating element or pump. In such cases, consulting a professional for repair is advisable.
Prevention Tips
1. Regular Maintenance
Regularly clean your dishwasher’s filters and perform maintenance as recommended by the manufacturer to prevent buildup and ensure optimal performance.
2. Water Softener
If hard water is a persistent problem, consider installing a water softening system in your home plumbing.
3. Proper Rinse Aid Use
Use rinse aid consistently and according to the recommended amounts to minimize spotting and filming on dishes.
