Check for clogged drain hose
If your dishwasher is not draining, the first thing you should check is the drain hose. A clogged drain hose is a common issue that can prevent the water from draining properly. To fix this, you’ll need to locate the drain hose, which is usually attached to the back of the dishwasher. Once you’ve found it, remove any debris or blockage that may be present. You can use a wire hanger or a plumbing snake to carefully push the clog out of the hose. Make sure to wear gloves and protect your eyes when doing this.
Clean the dishwasher filter
The dishwasher filter plays a crucial role in preventing food particles and debris from clogging the drain. Over time, the filter can become dirty and hinder the draining process. To fix a dishwasher that is not draining, remove the filter from the dishwasher and rinse it under running water. Use a soft brush or a toothbrush to scrub away any residue that may have accumulated. Once the filter is clean, place it back in the dishwasher and run a test cycle to see if the draining issue has been resolved.
Inspect the drain pump
If cleaning the drain hose and filter doesn’t solve the problem, it’s time to inspect the drain pump. The drain pump is responsible for pushing water out of the dishwasher and into the drain. To access the drain pump, you’ll need to remove the bottom panel of the dishwasher. Once you’ve done that, locate the drain pump and check for any obstructions. It’s not uncommon for small objects like bits of broken glass or utensils to get stuck in the pump. If you find anything blocking the pump, remove it and try running the dishwasher again.
Check the air gap
The air gap is a small device that is installed on the countertop or sink and is connected to the dishwasher drain hose. Its purpose is to prevent the backflow of water into the dishwasher. If the air gap is clogged or not functioning properly, it can cause drainage issues. To check the air gap, remove the cover and check for any debris or blockage. Use a small brush or toothpick to clean out any buildup. If the air gap is damaged or clogged beyond repair, you may need to replace it.
Call a professional
If you’ve tried all the above steps and your dishwasher is still not draining, it’s time to call a professional. There could be a more serious underlying issue that requires professional knowledge and tools to fix. A qualified technician will be able to diagnose the problem and provide the necessary repairs or replacements. It’s always best to seek professional help when dealing with complex appliance issues to ensure safety and avoid further damage.
