A malfunctioning dishwasher can be a major inconvenience, and a Whirlpool dishwasher not draining is a common problem that can leave you with a sink full of dirty dishes. But before you call a repair person, there are several things you can try to fix the issue yourself. This blog post will guide you through the most common reasons why your Whirlpool dishwasher isn’t draining and provide step-by-step instructions on how to troubleshoot and fix the problem.

Understanding the Draining Process

Before we dive into troubleshooting, it’s essential to understand how a dishwasher drains. The process typically involves a series of steps:
1. Water is pumped into the dishwasher.
2. The wash cycle completes, and the water is pumped out through the drain hose.
3. The drain hose empties into a drain line, typically connected to your kitchen sink.
If any part of this process is interrupted, the dishwasher won‘t drain properly.

Common Reasons Why Your Whirlpool Dishwasher Isn’t Draining

Here are some of the most frequent causes of a Whirlpool dishwasher not draining:

  • Clogged Drain Hose: This is the most common culprit. Food particles, grease, and other debris can accumulate in the drain hose, obstructing the flow of water.
  • Blocked Drain Line: The drain line connecting the dishwasher to the sink can also become clogged, preventing water from draining out.
  • Faulty Drain Pump: The drain pump is responsible for pushing water out of the dishwasher. If the pump malfunctions, it won’t be able to drain the water effectively.
  • Clogged Drain Filter: A clogged drain filter can prevent water from reaching the drain pump, leading to a backup.
  • Jammed Drain Impeller: The drain impeller is a part of the drain pump that helps move the water. If it becomes jammed, the pump won’t be able to drain the water.
  • Air Gap Issue: The air gap is a small device that prevents wastewater from backing up into the dishwasher. If the air gap is clogged or malfunctioning, it can interfere with the draining process.
  • Broken or Disconnected Drain Hose: A broken or disconnected drain hose can prevent water from draining properly.

How to Troubleshoot and Fix a Whirlpool Dishwasher Not Draining

Now that you understand the potential causes, let’s explore how to troubleshoot and fix each issue.

1. Check the Drain Hose

  • Locate the drain hose: The drain hose is typically located at the back of the dishwasher, connected to a drain line.
  • Disconnect the drain hose: Carefully disconnect the drain hose from the dishwasher and the drain line.
  • Inspect the hose: Look for any visible blockages, kinks, or cracks.
  • Clean the hose: If you find any debris, use a cleaning tool like a pipe cleaner or a wire hanger to clear the obstruction.
  • Reconnect the hose: Once the hose is clean, reconnect it to the dishwasher and the drain line securely.

2. Clear the Drain Line

  • Locate the drain line: The drain line is typically connected to the kitchen sink’s drain pipe.
  • Check for blockages: Look for any visible obstructions in the drain line.
  • Clean the drain line: You can use a plunger or a drain snake to clear any clogs in the drain line. You may also need to use a drain cleaner if the clog is severe.

3. Inspect the Drain Pump

  • Locate the drain pump: The drain pump is usually located at the bottom of the dishwasher.
  • Check for debris: Look for any debris or obstructions around the pump.
  • Listen for the pump’s operation: Turn on the dishwasher and listen for the pump to run. If you don’t hear it running, or if it makes unusual noises, the pump might be faulty.
  • Test the pump: You can test the drain pump with a multimeter. If the pump isn’t working, it will need to be replaced.

4. Clean the Drain Filter

  • Locate the drain filter: The drain filter is usually located at the bottom of the dishwasher, near the drain pump.
  • Remove the filter: Carefully remove the filter and inspect it for any debris or blockages.
  • Clean the filter: Rinse the filter under running water to remove any debris.
  • Replace the filter: Reinstall the filter securely in its place.

5. Check the Drain Impeller

  • Access the drain impeller: The drain impeller is usually located within the drain pump.
  • Check for obstructions: Look for any debris or blockages that may be preventing the impeller from spinning freely.
  • Clear any obstructions: Use a small tool to remove any debris or obstructions from the impeller.
  • Test the impeller: Turn on the dishwasher and listen for the impeller to spin. If it’s not spinning, it may need to be replaced.

6. Inspect the Air Gap

  • Locate the air gap: The air gap is typically located on the countertop near the dishwasher.
  • Check for debris: Look for any debris or blockages in the air gap.
  • Clean the air gap: Remove the air gap and clean it thoroughly with a brush or a small tool.
  • Replace the air gap: Reinstall the air gap securely in its place.

7. Examine the Drain Hose Connection

  • Check for leaks: Look for any leaks around the drain hose connections.
  • Tighten the connections: If you find any loose connections, tighten them securely.
  • Replace the hose: If the drain hose is cracked or broken, it will need to be replaced.

Troubleshooting Tips

  • Unplug the dishwasher: Before you start any troubleshooting, unplug the dishwasher from the power outlet to avoid electric shock.
  • Check the drain line: Make sure the drain line is properly connected to the sink drain and that there are no blockages.
  • Run a test cycle: After you’ve addressed any potential issues, run a test cycle to see if the dishwasher is draining properly.

When to Call a Professional

If you’ve tried all of the troubleshooting steps above and your Whirlpool dishwasher still isn’t draining, it’s time to call a professional appliance repair technician. They can diagnose the problem and make any necessary repairs.

Final Thoughts: Keeping Your Dishwasher Running Smoothly

By taking good care of your dishwasher, you can ensure it continues to serve you for years to come.
