A Whirlpool dishwasher that isn’t draining properly can cause a lot of inconvenience and lead to potential water damage in your kitchen. This guide will walk you through the common causes and solutions for when your Whirlpool dishwasher is not draining.
Understanding the Issue
Common Symptoms
- Water remains in the bottom of the dishwasher after a cycle.
- The dishwasher makes unusual noises, or the cycle stops midway.
- There is a noticeable odor of stagnant water inside the dishwasher.
Why is this happening?
Several issues can cause a Whirlpool dishwasher not to drain properly, ranging from simple clogs to more complex mechanical failures.
Step-by-Step Troubleshooting
Step 1: Check for Clogs in the Drain Hose
- Locate the Drain Hose: This hose usually connects the dishwasher to the garbage disposal or directly to the drain under the sink.
- Inspect for Kinks and Bends: Ensure that the hose is not bent or kinked, as this can restrict water flow.
- Clear Blockages: Disconnect the hose and pour water through it to clear any debris. If water doesn’t pass freely, use a plumber’s snake or a similar tool to remove the clog.
Step 2: Clean the Drain Filter and Sump
- Access the Filter: Remove the bottom rack of the dishwasher and locate the filter, a cylindrical screen typically located at the bottom.
- Clean the Filter: Unscrew the filter and rinse it under running water. Use a soft brush to remove any stuck-on food particles or debris.
- Check the Sump: The area around the filter (sump) can also collect debris. Clean out any residues that might be blocking the water flow.
Step 3: Examine the Garbage Disposal
- Recent Installation or Replacement: If you’ve recently installed or replaced a garbage disposal, make sure the drain plug inside the disposal inlet has been removed. This is a common oversight that blocks the dishwasher from draining.
- Clear Disposal: Run the garbage disposal to ensure it is clear of food waste, which can impede drainage from the dishwasher.
Step 4: Test the Drain Pump and Motor
- Locate the Pump: The pump is usually located beneath the dishwasher; you might need to remove the lower panel to access it.
- Check for Obstructions: Visually inspect the pump and the area around it for debris that might be blocking the impeller.
- Listen for Humming: If the pump hums but does not turn, it might be seized and needs replacement.
Step 5: Inspect the Air Gap (if applicable)
- Find the Air Gap: This small cylinder is usually located on the top of the sink or counter.
- Clean the Air Gap: Remove the cap and clear out any debris. Air gaps prevent water from siphoning back into the dishwasher but can become clogged.
Professional Help and Maintenance
When to Call a Professional
- If you’ve completed these steps and the dishwasher still won’t drain, or if you’re not comfortable performing any of these actions, it’s advisable to call a professional technician.
Regular Maintenance Tips
- Regularly cleaning the filter and ensuring the drain hose is clear of obstructions can prevent most draining issues.
- Run a dishwasher cleaner through a cycle periodically to maintain clean internal pipes and remove buildup.
Conclusion
A Whirlpool dishwasher not draining can typically be fixed with some basic troubleshooting steps. From checking for clogs in the drain hose to inspecting the drain pump, these actions can save you from more significant repairs. Regular maintenance is the best way to ensure your dishwasher runs smoothly for years to come.
