If you’ve opened your dishwasher after a wash cycle and found standing water in the bottom, you’re definitely not alone. A dishwasher that won’t drain can be pretty frustrating. But before you call for Toronto dishwasher repair, it’s worth checking a few common issues that might be causing the problem.
One of the most typical culprits is a clogged filter. Over time, bits of food, paper labels, and even broken glass can collect in the filter and block water from draining properly. The filter is usually found under the bottom spray arm — you can twist it out, rinse it under the tap, and clean out any debris with a soft brush.
Another possible issue is a blocked drain hose. This hose connects your dishwasher to your home’s plumbing. If it gets kinked or clogged with food or grease, the water can’t flow through. Try carefully removing the hose to check for blockages — just be ready with a towel because some water may spill out.
The drain pump could also be the problem. It’s meant to push water out of the machine, but it can get jammed or fail altogether. If you hear a strange humming noise or no sound at all when it's supposed to drain, this might be the cause. Replacing a pump can be a bit tricky, so you may want help if you’re not comfortable doing it yourself.
Sometimes, the issue isn’t with the dishwasher but with the garbage disposal or sink drain — especially if they share the same pipe. Run your garbage disposal and check for a clog in the sink. Some dishwashers also have a check valve that prevents backflow of water; if this valve is stuck, it might keep dirty water trapped.
To prevent future draining problems, it’s a good habit to scrape off food from your dishes before loading them. Don’t worry, you don’t need to pre-wash — just remove the larger bits.
If you’ve tried all these steps and the dishwasher still won’t empty, it might be time to contact a local appliance technician for help. But in many cases, a simple filter rinse or hose check can get things back to normal. Taking a few minutes to look over your machine might save you time and money in the long run.
