Why is my Kenmore dishwasher not draining?

If you’re experiencing issues with your Kenmore dishwasher not draining, it can be both frustrating and inconvenient. However, there are several common factors that could contribute to this problem. By understanding these potential causes, you can troubleshoot and resolve the issue more effectively.

1. Clogged Drain Hose

One possible reason for your Kenmore dishwasher not draining is a clogged drain hose. Over time, food particles, debris, and minerals can accumulate in the hose, obstructing the water flow. To check if this is the source of the problem, you can follow these steps:

  • Turn off the dishwasher and unplug it from the power source.
  • Locate the drain hose, which is usually located at the back of the dishwasher.
  • Disconnect the hose from both the dishwasher and the sink drain.
  • Inspect the hose for any blockages or kinks.
  • If you find any blockages, use a wire hanger or a long tool to remove them carefully.
  • Once cleared, reconnect the hose securely.

2. Clogged Garbage Disposal

Another potential culprit for a Kenmore dishwasher not draining is a clogged garbage disposal. If your dishwasher is connected to the garbage disposal, a blockage in the disposal can prevent proper drainage. To check and address this issue, follow these steps:

  1. Turn off the dishwasher and unplug it from the power source.
  2. Locate the drain hose connection on the garbage disposal.
  3. Disconnect the hose from the garbage disposal.
  4. Inspect the disposal for any clogs or debris.
  5. Remove any blockages with a wrench or pliers, if possible.
  6. After clearing the disposal, reconnect the drain hose securely.

3. Faulty Drain Pump

If your Kenmore dishwasher’s drain pump is faulty or not functioning properly, it can result in drainage issues. The drain pump is responsible for pumping the water out of the dishwasher. Here are some steps to troubleshoot this possible problem:

  • Turn off the dishwasher and unplug it from the power source.
  • Locate the drain pump, typically found at the bottom of the dishwasher.
  • Inspect the pump for any visible damage or blockages.
  • Manually rotate the pump’s impeller to check for smooth movement.
  • If the impeller is stuck or damaged, you may need to replace the drain pump.
  • Consult your dishwasher’s manual or contact a professional for assistance with replacing the pump.

4. Clogged Air Gap

An air gap device is typically installed on many dishwashers to prevent drain water from flowing back into the dishwasher. If this air gap becomes clogged with debris, it can impede proper drainage. Follow these steps to address this issue:

  1. Locate the air gap device, which is usually installed on the countertop or sink.
  2. Inspect the air gap for any visible blockages.
  3. Clean the air gap by removing the top cap and rinsing it thoroughly.
  4. Use a small brush or pipe cleaner to clear any debris from the air gap connections.
  5. Reassemble the air gap and run the dishwasher to check if the drainage problem is resolved.

5. Malfunctioning Drain Solenoid

The drain solenoid is responsible for opening the drain valve to allow water to flow out of the dishwasher. If the solenoid is defective or not working correctly, it can lead to drainage issues. To troubleshoot this problem, follow these steps:

  • Turn off the dishwasher and unplug it from the power source.
  • Locate the drain solenoid, usually found near the drain pump.
  • Inspect the solenoid for any visible damage or debris.
  • If the solenoid appears damaged, you may need to replace it.
  • Consult your dishwasher’s manual or seek professional assistance for replacing the solenoid.

In conclusion, there are various reasons why your Kenmore dishwasher may not be draining properly. By checking for a clogged drain hose, a clogged garbage disposal, a faulty drain pump, a clogged air gap, or a malfunctioning drain solenoid, you can identify and address the specific issue causing the drainage problem. If you are unsure or unable to resolve the problem on your own, it is recommended to seek assistance from a professional appliance repair technician.
