Why Is My Miele Dishwasher Not Cleaning Properly?

The Dishwasher Dilemma

So, you loaded up your fancy Miele dishwasher, pressed the button, and walked away—expecting spotless dishes, right? But instead, you open the door to find… grime, streaks, or even (gasp!) food residue still stuck on your plates. What gives?

Before you start blaming your dishwasher—or contemplating going back to handwashing—let’s troubleshoot the problem together. Trust me, the fix might be easier than you think!


1. Are You Loading It Correctly?

I know, I know—you’ve been loading dishwashers for years. But hear me out. Even the best dishwashers, including Miele, need proper spacing to get everything clean. Here are some quick checks:

Overcrowding? If dishes are crammed together, water and detergent can’t reach every surface. Try spacing things out a bit.
Blocking the Spray Arms? If a big pan or plate is blocking the rotating spray arms, some dishes might not get washed properly. Give those arms a spin before starting!
Facing the Right Way? Cups, bowls, and plates should be angled downward so water can actually reach them.

Quick Fix: Reload the dishwasher with these tips in mind and run another cycle. You might be surprised at the difference!


2. Are You Using the Right Detergent?

Not all dishwasher detergents are created equal, and Miele dishwashers tend to work best with high-quality, low-sudsing detergents.

Too Much or Too Little? Too much detergent can leave behind residue, while too little might not break down food and grease effectively. Follow the recommended amount on the packaging.
Miele’s Preferred Choice? Miele actually makes its own brand of detergent and rinse aid, optimized for its dishwashers. If you’re using generic brands and seeing lackluster results, it might be worth a switch!

Quick Fix: Try using Miele’s detergent or a high-quality alternative like Finish or Cascade, and ensure you’re measuring correctly.


3. Is the Water Hot Enough?

Dishwashers rely on hot water to break down grease and sanitize dishes. If your water isn’t hot enough, your dishes won’t get properly cleaned.

Ideal Temperature: Your dishwasher water should be at least 120°F (49°C). Lower temperatures may not dissolve grease and detergent efficiently.
Test It: Run your kitchen sink’s hot water for a minute before starting the dishwasher to ensure hot water is flowing.

Quick Fix: If your water heater is set too low, bump it up a few degrees and see if that improves cleaning performance.


4. Are the Spray Arms Clogged?

The spray arms are responsible for blasting water all over your dishes. If they’re clogged with debris or mineral buildup, your dishwasher won’t clean effectively.

How to Check: Remove the spray arms and inspect the holes. If they’re clogged with food particles or hard water buildup, soak them in vinegar and use a toothpick to clear any blockages.

Quick Fix: Clean your spray arms regularly to maintain optimal performance.


5. Is the Filter Dirty?

Miele dishwashers have a filter system that traps food debris. Over time, this can get clogged and prevent proper water circulation.

How to Clean:

  1. Locate the filter at the bottom of your dishwasher.
  2. Remove it and rinse it under warm water.
  3. Use a soft brush to scrub away any stubborn residue.

Quick Fix: Cleaning the filter once a month can prevent buildup and keep your dishwasher running efficiently.


6. Hard Water Could Be the Culprit

If you have hard water, mineral buildup can coat your dishwasher’s interior and clog spray arms, affecting cleaning performance.

Signs of Hard Water Issues: Cloudy glasses, white residue, and poor cleaning results.
Solution: Use a dishwasher cleaner with citric acid or add rinse aid to help prevent mineral buildup.

Quick Fix: Consider using Miele’s dishwasher salt and rinse aid for best results in hard water areas.


7. Try Running a Maintenance Wash

Just like any other appliance, dishwashers need a little TLC. If you’ve tried all of the above and still aren’t seeing results, a maintenance wash might do the trick.

How to Run a Maintenance Wash:

  1. Remove all dishes from the dishwasher.
  2. Place a dishwasher cleaner or a cup of white vinegar on the top rack.
  3. Run a hot water cycle to break down grease and remove buildup.

Quick Fix: Doing this once a month can keep your dishwasher running at peak performance.
