Is your Kenmore dishwasher not draining properly? This common issue can be frustrating, but don't worry – there are several potential causes and solutions. In this article, we'll explore why your dishwasher might be experiencing drainage problems and provide tips on how to address them. Whether it's a minor fix or time to call in the professionals, we've got you covered.

Understanding the Problem: Why Your Kenmore Dishwasher Won't Drain

Dealing with a dishwasher that won't drain can be a hassle. Here are some of the most common reasons behind this issue:

Blocked Filters

One of the simplest and most common causes of drainage problems is a blocked filter. Over time, food particles and debris can accumulate in the filter, preventing water from draining properly. To check and clean your filter:

• Turn off and unplug the dishwasher.
• Locate the filter at the bottom of the dishwasher.
• Remove the filter and rinse it under running water.
• Reinstall the filter and try running the dishwasher again.

Clogged Drain Hose

If the filter is clean, the next step is to inspect the drain hose. A clogged drain hose can stop water from exiting the dishwasher. To check the hose:

1. Disconnect the dishwasher from the power supply.
2. Locate the drain hose, usually found at the back of the appliance.
3. Check for kinks or blockages in the hose and clear them if necessary.
4. Reattach the hose and test the dishwasher.

Garbage Disposal Connection Issues

If your dishwasher drain hose is connected to a garbage disposal, ensure the disposal unit's knockout plug is removed. This plug is often left in place during installation, causing drainage issues. To fix this:

• Turn off the garbage disposal and dishwasher.
• Locate the knockout plug inside the disposal's inlet.
• Remove the plug with a screwdriver or pliers.
• Reconnect the hose and test the dishwasher.

Improper Drain Hose Configuration

The configuration of the drain hose can also impact drainage. The hose should loop upward to prevent backflow. Ensure the hose is installed correctly:

1. Check that the hose forms a high loop under the sink.
2. Secure the hose in place with a bracket or clip.
3. Test the dishwasher to see if the problem is resolved.

Soap Residue Build-Up

Excessive soap residue can cause blockages in the drain pump. If you notice suds in the water, this might be the issue. Run a cleaning cycle with a dishwasher cleaner to remove residue and improve drainage.

Drain Pump Issues

If none of the above solutions work, the problem might be with the drain pump itself. A broken impeller or a failed pump may need professional repair or replacement. In such cases, it's best to call a professional technician to avoid further damage.

Safety Recommendations

When dealing with appliance repairs, safety is paramount. Always follow these guidelines:

• Turn off the power supply before inspecting or repairing your dishwasher.
• Use appropriate tools and wear protective gear if necessary.
• Avoid attempting complex repairs if you're not experienced; call a professional instead.
