Whirlpool Stackable Washer Won T Drain

Introduction

Discovering your Whirlpool stackable washer isn’t draining can be a real headache. It means wet clothes are stuck inside, and you can’t start another load. This problem often happens after a particularly large load or when washing items that shed a lot of lint. Addressing this issue quickly is important to prevent mold growth, unpleasant odors, and potential damage to your washing machine and your laundry room.

Common Causes of Whirlpool Stackable Washer Won’t Drain

Here are some of the most common reasons why your Whirlpool stackable washer might refuse to drain:

• Clogged Drain Hose: This is a frequent culprit. Lint, small objects (like socks or buttons), or soap buildup can block the hose, preventing water from flowing out.
• Blocked Drain Pump Filter: The filter is designed to catch debris before it reaches the drain pump. If it’s full, it can restrict water flow.
• Malfunctioning Drain Pump: The drain pump is responsible for actively pushing the water out. If it’s faulty, it won’t be able to do its job.
• Kinked or Twisted Drain Hose: A kink in the drain hose restricts water flow.
• Air Lock: Sometimes, air can get trapped in the drain hose, creating a sort of “air lock” that prevents water from flowing freely.
• Lid Switch Issues: Some washers won’t drain if the lid switch (which detects if the lid is closed) is broken. While less common with stackable units, it’s a possibility.
• Faulty Water Level Sensor: If the water level sensor is malfunctioning, it may incorrectly signal that the washer is empty, preventing the drain cycle from starting.
• Control Board Problems: In rare cases, a problem with the washer’s control board (the “brain” of the machine) can cause draining issues.

Symptoms Checklist

Look for these signs to confirm the draining problem:

• Standing water in the washer drum after a completed cycle.
• The washer makes a humming or buzzing noise during the drain cycle, but no water is being pumped out.
• Error codes related to draining appear on the washer’s display panel.
• The drain hose appears to be bulging or kinked.
• The drain pump filter is visibly clogged with lint and debris.

How to Fix Whirlpool Stackable Washer Won’t Drain Step-by-Step Guide

Follow these steps to troubleshoot and fix the draining issue:

1. Unplug the Washer: Safety first! Disconnect the washer from the power outlet before you start any troubleshooting.
2. Check the Drain Hose: Locate the drain hose at the back of the washer. Make sure it’s not kinked, twisted, or crushed. Straighten it out if necessary.
3. Inspect the Drain Hose Connection: Ensure the drain hose is securely connected to both the washer and the drainpipe. Loose connections can cause draining problems.
4. Check the Drainpipe: Make sure the drainpipe where the washer’s hose empties isn’t clogged. You can use a plumbing snake or a bent wire hanger to clear any blockages.
5. Locate and Clean the Drain Pump Filter: This is usually located at the front bottom of the washer, behind a small access panel. Place a towel or shallow pan underneath to catch any spilled water. Unscrew the filter (usually counterclockwise) and remove it.
6. Clean the Filter: Rinse the drain pump filter thoroughly under running water to remove lint, debris, and any other obstructions.
7. Inspect the Drain Pump Area: While the filter is removed, shine a flashlight into the drain pump area. Check for any visible obstructions, such as coins or small objects. Remove anything you find.
8. Reinstall the Filter: Carefully screw the drain pump filter back into place, making sure it’s properly seated and tightened.
9. Check for an Air Lock: Disconnect the drain hose from the drainpipe and lower it into a bucket. Run a short drain cycle. If water gushes out forcefully, an air lock was likely the problem.
10. Reset the Washer: Sometimes, a simple reset can resolve the issue. Unplug the washer for 1-2 minutes, then plug it back in.
11. Run a Test Cycle: Select a short wash/drain cycle and observe if the washer drains properly.
12. Check the Washer’s Manual: Your washer’s manual may have specific instructions for troubleshooting draining problems or running diagnostic tests.

Fix the Issue Without Buying Parts

Before considering replacing any parts, try these free methods:

• Reset: Unplugging the washer for a few minutes often resolves minor electrical glitches.
• Cleaning: Regularly clean the drain pump filter (every 1-3 months) to prevent clogs.
• Recalibration (if applicable): Some models have a recalibration cycle. Consult your owner’s manual.
• Inspection Tips: Routinely check the drain hose for kinks or damage.
• Maintenance Basics: Use the correct amount of detergent to prevent excessive suds that can clog the drain pump.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the washer still won’t drain, the drain pump itself might be faulty and need replacement. This usually costs between $50 and $200 for the part, plus labor if you hire a technician. Another potential issue that may require replacement is a faulty water level sensor. Control board replacements are the most expensive option, and might warrant considering a new machine.

Safety Warning

• Always unplug the washer before performing any troubleshooting or repairs.
• Be careful when handling water and electrical components. Avoid working on wet floors.
• If you’re uncomfortable with any of these steps, consult a qualified appliance repair technician.

Tools You May Need

• Screwdriver (Phillips and flathead)
