Is your Frigidaire dishwasher leaving standing water at the bottom after a cycle? A dishwasher that won’t drain is frustrating, but don’t panic—I’ve fixed this issue myself multiple times and will guide you through the most common causes and solutions. Let’s get your dishwasher draining properly again with simple, step-by-step troubleshooting.
Why Trust This Guide?
As a certified appliance technician with 15+ years of experience, I’ve repaired hundreds of Frigidaire dishwashers. This guide combines my expertise with practical, easy-to-follow advice. No jargon—just clear solutions that work.
1. Check the Dishwasher Filter (Most Common Fix)
Frigidaire dishwashers have a self-cleaning filter system, but food debris or grease can still clog it over time.
How to Fix:
- Turn off the dishwasher and remove the bottom rack.
- Locate the circular or rectangular filter at the bottom (consult your manual if unsure).
- Twist and lift the filter to remove it. Rinse under warm water to clear debris.
- Reinstall the filter securely and run a rinse cycle to test.
Pro Tip: Clean the filter monthly to prevent future clogs.
2. Inspect the Drain Hose for Blockages
A kinked or clogged drain hose stops water from escaping.
How to Fix:
- Unplug the dishwasher for safety.
- Locate the drain hose (usually connected under the sink or to the garbage disposal).
- Detach the hose and check for twists, kinks, or food buildup. Use a pipe cleaner or vinegar to clear blockages.
- Reconnect the hose tightly and ensure it’s positioned higher than the disposal to prevent backflow.
3. Test the Drain Pump
The drain pump pushes water out of the dishwasher. If it’s faulty, water won’t drain.
How to Fix:
- Listen for a humming sound during the drain cycle. No noise? The pump may be dead.
- Access the pump (under the dishwasher, behind the kickplate).
- Check for obstructions like glass shards or utensils. If clear, use a multimeter to test for continuity. Replace the pump if it fails the test.
4. Check the Garbage Disposal Connection
If your dishwasher drains into a garbage disposal, a clogged disposal inlet can cause backups.
How to Fix:
- Run the disposal to clear any debris.
- Remove the dishwasher drain hose from the disposal and clean the inlet with a brush.
- Reattach the hose securely.
5. Look for a Faulty Check Valve
The check valve (or drain valve) prevents water from flowing back into the dishwasher. If stuck, it blocks drainage.
How to Fix:
- Locate the check valve near the drain pump.
- Remove it and check for debris or damage. Soak it in warm, soapy water to loosen grime. Replace if cracked or worn.
When to Call a Professional
If these steps don’t solve the problem, you may have a faulty control board, clogged air gap, or broken motor. Contact Frigidaire support or a licensed technician for advanced repairs.
Prevent Future Drain Issues
- Scrape food off dishes before loading.
- Run hot water in the sink before starting the dishwasher.
- Use a monthly cleaning cycle with vinegar or dishwasher cleaner.
