Unveiling The Mystery: How To Resolve Whirlpool Dishwasher Drainage Woes

A malfunctioning dishwasher can be a major inconvenience, especially when it refuses to drain. If you’re facing this issue with your Whirlpool dishwasher, don’t despair. This comprehensive guide will walk you through the most common causes and provide step-by-step instructions on how to fix a Whirlpool dishwasher not draining.

Identifying the Root Cause

Before attempting any repairs, it’s crucial to identify the underlying cause of the drainage problem. Here are some possible culprits:

• Clogged drain hose or filter
• Faulty drain pump
• Broken or disconnected air gap
• Malfunctioning electronic control board

Troubleshooting and Repair Steps

1. Check the Drain Hose and Filter

Start by inspecting the drain hose for kinks or blockages. If it’s kinked, gently straighten it out. Clean the drain filter located at the bottom of the dishwasher by removing any food particles or debris.

2. Test the Drain Pump

If the drain hose and filter are clear, the next step is to test the drain pump. Unplug the dishwasher and locate the drain pump, which is usually situated at the bottom of the unit. Use a multimeter to check for continuity between the pump’s terminals. If there’s no continuity, the pump needs to be replaced.

3. Inspect the Air Gap

The air gap is a small device installed on the countertop that prevents wastewater from flowing back into the dishwasher. Check if the air gap is clogged or disconnected. Clean or reconnect it as necessary.

4. Reset the Dishwasher

Sometimes, a simple reset can resolve drainage issues. Unplug the dishwasher for 30 seconds, then plug it back in. This may reset the electronic control board and restore proper drainage.

5. Check the Dishwasher’s Internal Plumbing

If the above steps haven’t solved the problem, it’s possible that the dishwasher’s internal plumbing is clogged. Disconnect the water supply line and remove the lower access panel to inspect the hoses and connections. Look for any blockages or leaks and clean or replace any damaged components.

6. Replace the Electronic Control Board

If the drain pump, air gap, and internal plumbing are all functioning properly, the issue may lie with the electronic control board. This board controls the dishwasher’s functions, including drainage. If it’s faulty, it may need to be replaced by a qualified technician.

When to Call a Professional

While many Whirlpool dishwasher drainage issues can be resolved with basic troubleshooting, some may require professional assistance. If you’re not comfortable performing the repairs yourself, or if the problem persists after following the steps above, contact a certified appliance repair technician.

The Final Verdict

Fixing a Whirlpool dishwasher not draining can be a straightforward process if you follow the steps outlined in this guide. By identifying the root cause and applying the appropriate repair methods, you can restore your dishwasher to optimal working condition. Remember, if the issue is beyond your comfort level or expertise, don’t hesitate to seek professional help.
