Dishwasher drain blockage? follow these steps to unclog your miele

When your Miele dishwasher fails to drain, it can be a frustrating and inconvenient issue. Understanding the underlying causes can help you resolve the problem efficiently. In this detailed guide, we will explore the various reasons why your Miele dishwasher may not be draining and provide step-by-step instructions for troubleshooting and repair.

Common Causes of Miele Dishwasher Drainage Issues

• Clogged Drain Hose: Over time, food particles, grease, and other debris can accumulate in the drain hose, obstructing the flow of water.
• Blocked Drain Filter: The drain filter is designed to trap food debris and prevent it from clogging the drain hose. However, if the filter becomes overloaded or clogged, it can restrict the water flow.
• Faulty Drain Pump: The drain pump is responsible for pumping water out of the dishwasher. A malfunctioning drain pump can prevent the water from draining properly.
• Clogged Air Gap: The air gap is a small device installed at the sink to prevent contaminated water from flowing back into the dishwasher. If the air gap becomes clogged, it can create a vacuum that prevents the dishwasher from draining.
• Kinked or Crushed Drain Hose: A kinked or crushed drain hose can restrict the flow of water and prevent the dishwasher from draining effectively.
• Damaged or Leaking Sump Assembly: The sump assembly is the bottom part of the dishwasher where the drain pump is located. If the sump assembly is damaged or leaking, it can prevent the dishwasher from draining properly.
• Electrical Issues: In rare cases, electrical issues, such as a faulty wiring harness or a blown fuse, can disrupt the power supply to the drain pump, preventing it from functioning.
