Frustrated with a non-draining miele dishwasher? find the answer here

A malfunctioning dishwasher can be a major inconvenience, especially when you’re faced with a pile of dirty dishes. If your Miele dishwasher is not draining properly, it’s essential to identify the root cause and find an effective solution. In this blog post, we will explore the various reasons why your Miele dishwasher may not be draining and provide step-by-step instructions on how to resolve the issue.

Common Causes of Dishwasher Drainage Problems

• Clogged Drain Hose: Over time, food particles, grease, and other debris can accumulate in the drain hose, obstructing the water flow.
• Clogged Filter: The dishwasher filter traps food scraps and debris, preventing them from entering the drain pump. A clogged filter can restrict water flow and cause drainage issues.
• Faulty Drain Pump: The drain pump is responsible for pumping the water out of the dishwasher. A faulty drain pump can prevent the dishwasher from draining properly.
• Kinked or Crushed Drain Hose: A kinked or crushed drain hose can restrict water flow and prevent the dishwasher from draining.
• Blockage in the Air Gap: The air gap is a small device installed on the kitchen sink to prevent water from flowing back into the dishwasher. A blockage in the air gap can cause drainage problems.
• Overflow Float Switch: The overflow float switch is a safety feature that shuts off the dishwasher if the water level rises too high. A faulty overflow float switch can prevent the dishwasher from draining properly.
• Malfunctioning Control Board: The control board is the brain of the dishwasher, controlling all its functions. A malfunctioning control board can lead to various issues, including drainage problems.

Troubleshooting and Repair Steps

1. Check the Drain Hose for Clogs:

• Disconnect the drain hose from the dishwasher and inspect it for any blockages.
• Use a flashlight to look for any visible debris or kinks.
• If you find a blockage, use a drain snake or a pair of pliers to remove it.

2. Clean the Filter:

• Locate the dishwasher filter and remove it by unscrewing or pulling it out.
• Rinse the filter thoroughly with water to remove any food scraps or debris.
• Reinstall the filter and ensure it’s securely in place.

3. Inspect the Drain Pump:

• Disconnect the power supply to the dishwasher.
• Locate the drain pump and remove it by unscrewing the bolts or clips holding it in place.
• Check if the pump impeller is damaged or clogged.
• If necessary, replace the drain pump with a new one.

4. Check for Kinks or Crushes in the Drain Hose:

• Inspect the entire length of the drain hose for any kinks or crushes.
• If you find any, straighten the hose or replace it with a new one.

5. Clear Blockage in the Air Gap:

• Locate the air gap on the kitchen sink.
• Remove the cap and check for any blockages.
• Use a small brush or a wire to clear any debris.

6. Test the Overflow Float Switch:

• Fill a glass with water and pour it into the dishwasher tub.
• If the water level rises too high and the dishwasher does not drain, the overflow float switch may be faulty.
• Replace the overflow float switch with a new one.
