If you’ve opened your Whirlpool dishwasher after a cycle only to find standing water inside, you’re not alone. A dishwasher that doesn’t drain is a common issue that many homeowners face. Not only is it inconvenient, but it can also be a sign of a more serious underlying problem. In this post, we’ll walk you through the possible reasons your Whirlpool dishwasher isn’t draining and how you can address the issue—plus when it’s time to call in the professionals at Express Repair.
1. Clogged Drain Hose
One of the most frequent culprits is a blocked drain hose. Over time, food particles, grease, and debris can build up and prevent water from draining properly.
2. Dirty Filter or Drain Basket
A dirty or clogged filter can also block water flow. Whirlpool dishwashers have a removable filter near the bottom of the tub that should be cleaned regularly to avoid drainage issues.
3. Faulty Drain Pump
The drain pump is responsible for pushing the water out of the dishwasher. If it fails, the water won’t drain and may require a professional replacement.
4. Garbage Disposal Connection
If your dishwasher is connected to a garbage disposal, make sure the knockout plug was removed during installation. If not, it can block drainage.
5. Air Gap Issues
Some setups include an air gap (a small cylinder on the sink or countertop). If it becomes clogged, water may back up into the dishwasher.
6. Kinked or Improperly Installed Drain Hose
Improper hose placement or a kink in the line can restrict water flow and prevent proper drainage.
Before calling a technician, you can try these simple steps:
Check the filter and drain basket: Remove and clean any food debris or blockages.
Inspect the drain hose: Make sure it isn’t kinked and is securely connected.
Run a cleaning cycle: Try running a dishwasher cleaner through a cycle to clear buildup.
Listen to the drain pump: If it’s making strange noises or not running, it may need repair or replacement.
If you’ve tried the steps above and your Whirlpool dishwasher still isn’t draining, it’s time to call in an expert. Ignoring the issue can lead to water damage, mold, or further appliance failure.
