How to Fix a Clogged Dishwasher in 5 Easy Steps

Step 1: Inspect the Draining System

Is there a problem with your dishwasher’s draining system? When your dishwasher gets stuck or stops working, it can be very annoying, but don’t worry—we can help! Whether your dishwasher is from Bosch, Frigidaire, GE, LG, Whirlpool, Kitchen Aid, or Samsung, this guide will show you how to fix it fast. We’ll also provide you with tips about how to keep it functioning well for years to come.

Over time, Food particles or mineral accumulation can clog the dishwasher’s drain pump or hose, preventing the water from draining correctly. Many dishwashers, including Miele and GE, have this problem: they don’t drain.

How to Fix:

1. Disconnect the dishwasher’s power and water.
2. Look for the drain hose, which is usually at the back of the machine, next to the sink or garbage disposal.
3. Take off the hose.
4. Check the hose for any obvious kinks or clogs.
5. Use a long brush or water to clean the hose and get rid of any dirt.
6. Put the hose back together correctly.

Tip: If you notice a significant amount of buildup, consider replacing the hose to avoid recurring issues.

Step 2: Inspect the Garbage Disposal

A clogged or jammed garbage disposal can stop your dishwasher from draining properly. If you’re wondering, “Why is my dishwasher not draining even though I don’t see any blockage?”
The garbage disposal could be the reason.

How to Fix:

1. Check that the trash disposal is blocked or choked.
2. Run the disposal for a few seconds to get rid of any trash.
3. If the disposal is still blocked, you may have to use a plunger or take out the stuff by hand.

Tip: Be careful while using the trash disposal. Don’t dump big pieces of food or oil down the drain.

Step 3: Clean the Filter and Drain

Over time, food scraps, grease, and debris can build up in the dishwasher’s filter and drain. This is especially common in Frigidaire dishwashers that aren’t emptying properly, or in other models that tend to collect dirt more easily.

How to Fix:

1. Find the dishwasher filter (it’s generally located at the bottom).
2. Take out the filter and rinse it in warm water.
3.  Use a soft brush or towel to get rid of any remaining dirt.
4. Look around the drain for bits of food and clean them up if you find any.

Tip: Cleaning the filter at least once a month might help keep it from becoming clogged again.

Step 4: Check the Pump for Blockages

Food scraps or small hard objects can fall into the dishwasher and clog the pump. This issue is especially common in LG dishwashers that aren’t emptying or Samsung dishwashers that aren’t draining.

How to Fix:

1. Take out any water that is still in the dishwasher.
2. Find the pump, which is normally at the bottom of the dishwasher.
3. Check for any apparent obstacles, such as small objects or food particles.
4. Get rid of any trash in the pump area by carefully taking it away.

Tip: Don’t put hard things or utensils on the bottom rack to prevent the pump from becoming damaged.

Step 5: Test the Drainage After Fixing

After completing the repairs, make sure your dishwasher is draining properly. If your Miele dishwasher still isn’t emptying, the pump or drain line may need additional attention.

How to Fix:

1. You can test the dishwasher’s draining process after cleaning the drain hose, trash disposal, filter, and pump.
   2. Restart the dishwasher, choose a short wash cycle, and let it run.
   3. After the cycle is over, open the door and see whether all the water has drained.

Tip: If the water still doesn’t drain properly, there may be an issue with the dishwasher’s drain valve, which will require professional dishwasher repair.
