A dishwasher that won’t drain is one of the most common household appliance issues, and it can be frustrating when dirty water pools at the bottom of your machine. If you’re dealing with this problem in Adelaide, knowing whether you can fix it yourself—or if you need professional dishwasher repairs in Adelaide—will save you both time and stress.
Common Reasons Why Your Dishwasher Won’t Drain
Blocked Filter
Over time, food scraps, grease, and debris can clog the filter at the bottom of your dishwasher. A blocked filter prevents water from draining effectively.
Clogged Drain Hose
The drain hose can become kinked or clogged with residue. This is a common cause of poor drainage and may require detaching and cleaning the hose.
Garbage Disposal Connection
If your dishwasher is connected to a garbage disposal unit, a blockage in the disposal can also stop the dishwasher from draining properly.
Faulty Drain Pump
The drain pump is responsible for pushing water out of the dishwasher. If it fails, you may hear unusual noises or no sound at all when the dishwasher tries to drain.
Air Gap Issues
Some Adelaide homes have an air gap fitted near the sink. If this becomes clogged, it can prevent your dishwasher from draining.
DIY Fixes You Can Try Before Calling a Technician
Clean the Filter:
Remove and rinse the filter under hot water. Scrub away any built-up grime with a soft brush.
Check the Drain Hose:
Make sure it isn’t kinked. If possible, disconnect it and flush it out with water.
Inspect the Garbage Disposal:
Run your disposal to clear any clogs, and check for food buildup.
Run Hot Water:
Before starting your dishwasher, run hot water through your sink. This helps dissolve grease and makes it easier for the dishwasher to drain.
If you’ve tried these steps and your dishwasher still isn’t draining, it may be time to call in a professional for dishwasher repairs in Adelaide.
