There’s nothing quite like the sinking feeling of opening your dishwasher, expecting sparkling clean dishes, only to be greeted by food scraps and grime. If you have this kind of dishwasher, you’re not along. This is a surprisingly common problem; the good news is that it often has a simple solution.

In many cases, the cause of dirty dishes is something you can fix yourself with a few quick checks and adjustments. However, some issues may require the expertise of a professional appliance repair technician. 

Let’s look at some of the most common culprits behind dirty dishes.

Common Culprits Behind Dirty Dishes

Your dishwasher is a machine, yes? Maybe you’re expecting too much to do hard work. And then you suspect something is wrong. Let’s see why dishwashers go awry.

Improper Loading

It might seem like a no-brainer, but how you load your dishwasher can make a difference.

• Overcrowding: Cramming too many dishes leaves little room for water and detergent to circulate, resulting in grime left behind on dishes.
• Blocking spray arms: Ensure that large items don’t prevent the spray arms from spinning freely. Dishes should be angled downward to allow water to run off, and silverware should be placed with handles down to avoid nesting.

Hard Water Issues

If you live in an area with hard water (common in Miami), mineral deposits can build up on your dishes and inside your dishwasher, making it less effective.
The minerals in hard water can prevent detergent from dissolving properly and leave a cloudy film on glasses and silverware.

Over time, hard water can damage your dishwasher’s components. A water softener can help address this problem.

Clogged Filter

Your dishwasher’s filter is crucial in trapping food particles and debris. If it gets clogged, these particles can recirculate and end up back on your dishes.

Check your dishwasher’s manual to determine how often the filter should be cleaned, but a good rule of thumb is once a month.

Detergent Problems

Using the wrong detergent or insufficient can lead to less-than-stellar results.

Wrong type: Regular dish soap creates too many suds and isn’t formulated for dishwashers. Always use detergent specifically designed for automatic dishwashers.

Old or clumpy: Check the expiration date and discard any detergent that has hardened or become lumpy.

Too little: Follow the manufacturer’s recommendations for the correct amount of detergent based on your water hardness and the size of your load.

Failing Components

Sometimes, the problem isn’t with your loading or detergent but with a part of the dishwasher.

Spray arms: Check for clogs or cracks in the spray arms.

Door gasket: Inspect the rubber gasket around the door for signs of wear or damage. A faulty gasket can cause leaks, interfering with the cleaning process.

If you’ve tried all of these basic troubleshooting tips and your dishwasher is still not cleaning properly, it may be time to call in a professional. Some issues, like replacing faulty parts, require specialized knowledge and tools that most homeowners don’t have.

Troubleshooting Tips (DIY-Friendly)

Before calling a repair technician, there are a few simple steps you can take to try to resolve the issue on your own:

1. Double-check loading: Refer to your dishwasher’s manual for specific instructions on how to load dishes properly. Make sure you’re not blocking the spray arms and that there’s enough space for water to circulate.
2. Run the garbage disposal: Food particles left in the disposal can clog your dishwasher’s filter. Run the disposal before starting a wash cycle to remove any lingering debris.
3. Experiment with detergent: Try slightly adjusting the amount of detergent you use. Too little detergent won’t clean effectively, but using too much can leave a residue. It may take a bit of experimentation to find the right amount for your water hardness and load size.
4. Visually inspect: Remove the bottom rack and check the filter for any visible blockages. Also, examine the spray arms for cracks or clogs. Clean the filter and clear any debris from the spray arms if you see any issues.

By following these simple troubleshooting tips, you may be able to fix your dishwasher problems without having to call a repair technician. However, if you’ve tried these steps and your dishes are still coming out dirty, it’s time to consider seeking a technician’s help.

When to Call a Pro

While some dishwasher issues are easily fixable, others call for professional attention. Here’s when it’s time to pick up the phone:

• Basic troubleshooting fails: If you’ve tried the DIY tips mentioned above and your dishwasher is still not cleaning properly, have it checked by a technician.
• Hard water woes: Cloudy glassware, white spots on dishes, and a gradual decrease in cleaning performance can all point to hard water issues. A professional can assess your water and recommend the best solutions, such as a water softener.
• Leaks or unusual noises: These are telltale signs of a deeper problem, like a faulty pump or worn gasket. Don’t attempt to fix these yourself, as water and electricity can be dangerous.
• You’re uncomfortable with DIY repairs: If you’re unsure about disassembling your dishwasher or dealing with potential electrical issues, don’t hesitate to seek help.
