Dishwasher Not Draining Like it Should? Here's How to Fix It
Is your dishwasher not draining properly? Many homeowners face this pervasive and frustrating issue after a wash cycle. Whether you're dealing with a clogged dishwasher or water in the bottom of your dishwasher when it's not in use, let us help you understand why your dishwasher won't drain and how to fix it.
Let's examine the common causes of a dishwasher not draining entirely and show practical solutions for getting your appliance back in working order.
Common Causes of a Dishwasher Not Draining
When you open your dishwasher and find it full of water, it's natural to panic and ask yourself, "Why is my dishwasher not draining?" Several factors can contribute to this problem:
Clogged Filters and Debris Buildup
A clogged filter is one of the most common reasons a dishwasher does not drain. Over time, food particles, grease, and other debris can accumulate in the filter, preventing water from draining correctly. Imagine trying to drink a thick milkshake through a tiny straw—essentially, this is what happens when your dishwasher filter is clogged.
To check if this is the issue:
- Locate the filter at the bottom of your dishwasher.
- Remove it carefully.
- Rinse it under running water.
- Use a soft brush to remove any stubborn debris.
Regular filter cleaning can prevent this issue from recurring. Think of it as giving your dishwasher a mini-spa treatment - it'll thank you with better performance!
Blocked Drain Hose
Another common reason dishwashers don't drain is a blocked drain hose. This hose connects your dishwasher to the sink drain or garbage disposal. Water can't flow out properly if it becomes kinked, clogged, or damaged.
To inspect the drain hose:
- Disconnect the hose from both the dishwasher and the sink drain.
- Check for any visible blockages or kinks.
- Try blowing through the hose to test for airflow.
If you can't blow through it quickly, you've likely found your problem. Clearing or replacing the hose if damaged can often solve the draining issue.
Faulty Drain Pump
The drain pump is the heart of your dishwasher's draining system. If it's not working correctly, your dishwasher will have standing water. Listen for a humming noise when your dishwasher should be draining. If you hear it but the water isn't moving, the pump might struggle to do its job.
Testing the drain pump usually requires technical know-how, so if you suspect this is the issue, it might be time to call RooterPLUS! for help.
How to Unclog a Dishwasher: DIY Solutions
There are steps you can take to try and fix a clogged dishwasher drain yourself:
The Vinegar and Baking Soda Method
This classic cleaning duo can help unclog the dishwasher. Here's how to use it:
- Remove any standing water from the dishwasher.
- Pour 1 cup of baking soda into the bottom of the dishwasher.
- Follow with 1 cup of white vinegar.
- Let the mixture sit for about 15 minutes.
- Run a hot water cycle.
This fizzy reaction can help break down minor clogs and freshen your dishwasher at the same time. It's like giving your appliance a refreshing bubble bath.
Plunger Power
Yes, the same tool you use for your toilet can help unclog your dishwasher.
- Remove the bottom rack.
- Place a plunger over the drain.
- Fill the bottom of the dishwasher with a couple of inches of water.
- Plunge vigorously several times.
The suction created can often dislodge minor blockages. Use a clean plunger—you don't want to transfer bathroom bacteria to your dishwasher!
Check the Air Gap
If your sink has an air gap (a small cylinder next to the faucet), it could be the source of your draining woes. Sometimes, debris can collect here and cause drainage issues. Cleaning it out is simple:
- Remove the air gap cover.
- Clean out any debris you find inside.
- Replace the cover.
