Solving The Riddle: Why Is My Miele Dishwasher Not Draining?

If your Miele dishwasher is leaving you with a sink full of dirty dishes, it’s time to investigate the culprit behind its drainage woes. Understanding the underlying causes can help you diagnose and resolve the issue effectively.

Common Causes of Dishwasher Drainage Problems

1. Clogged Drain Hose

One of the most common reasons for a dishwasher not draining is a clogged drain hose. Over time, food particles, grease, and other debris can accumulate in the hose, obstructing the flow of water.

2. Blocked Filter

The dishwasher filter traps food particles and debris to prevent them from clogging the drain pump. However, if the filter becomes overloaded, it can hinder the water’s ability to drain properly.

3. Faulty Drain Pump

The drain pump is responsible for pumping water out of the dishwasher. If the pump malfunctions or becomes clogged, it can lead to drainage problems.

4. Kinked or Crushed Drain Hose

If the drain hose is kinked or crushed, it can restrict the flow of water and prevent the dishwasher from draining effectively.

5. Float Switch Malfunction

The float switch detects the water level in the dishwasher. If the float switch malfunctions or becomes stuck, it can prevent the dishwasher from draining properly.

6. Air Gap Clog

The air gap is a small device installed on the kitchen sink to prevent dirty water from flowing back into the dishwasher. If the air gap becomes clogged, it can disrupt the drainage process.

Troubleshooting Steps

1. Inspect the Drain Hose

Disconnect the drain hose from the dishwasher and check for any clogs or obstructions. If you find any, remove them carefully.

2. Clean the Filter

Locate the dishwasher filter and remove it. Clean the filter thoroughly with warm water and a soft brush.

3. Test the Drain Pump

To test the drain pump, run the dishwasher without any dishes in it. If the water does not drain, the pump may be faulty and require replacement.

4. Inspect the Drain Hose for Kinks or Crushes

Check the entire length of the drain hose for any kinks or crushes. If you find any, straighten the hose and reconnect it to the dishwasher.

5. Check the Float Switch

Find the float switch in the dishwasher and check if it moves freely. If it is stuck or malfunctioning, it may need to be replaced.

6. Clean the Air Gap

Locate the air gap on the kitchen sink and remove the cap. Clean the air gap thoroughly with warm water and a soft brush.

Additional Tips

• Run the dishwasher regularly, even if it’s not full. This helps prevent food particles from accumulating in the drain.
• Use a dishwasher cleaner periodically to remove any buildup in the drain and other components.
• If you have a garbage disposal, make sure it is working properly as it can affect the dishwasher’s drainage.

The Final Word: Preventing Future Dishwasher Drainage Issues

By following these troubleshooting steps and implementing the additional tips, you can effectively resolve your Miele dishwasher‘s drainage problems. Regular maintenance and proper usage will help prevent future issues and keep your dishwasher draining smoothly for years to come.
