Common Causes and Solutions for a Dishwasher That Won’t Drain
Is your dishwasher not draining properly? This can be a frustrating problem to deal with, as it can leave your dishes dirty and your kitchen smelling unpleasant. Fortunately, there are several common causes for a dishwasher not draining, and most of them have simple solutions. In this article, we will discuss the possible reasons behind this issue and provide you with practical tips to fix it.
Clogged Drain Hose
One of the most frequent culprits behind a dishwasher not draining is a clogged drain hose. Over time, food particles, debris, or even small objects like utensils can accumulate in the hose and cause blockages. To check if this is the problem, start by disconnecting the drain hose from both the dishwasher and the sink drain. Inspect it thoroughly for any signs of blockage or damage. If you find any obstructions, use a long wire brush or pipe cleaner to remove them gently. Once cleared, reconnect the hose and test if your dishwasher drains properly.
Blocked Air Gap
Another common cause of a dishwasher that won’t drain is a blocked air gap. The air gap is a small device located on top of your sink or countertop near the faucet. Its purpose is to prevent wastewater from flowing back into your dishwasher by creating an air break between the appliance and your plumbing system. However, over time, debris like soap scum or food particles can accumulate in the air gap and cause drainage issues. To fix this problem, simply remove the cap from the air gap and clean out any debris using a toothbrush or pipe cleaner. Once cleaned, reattach the cap and run your dishwasher to see if it drains properly.
Faulty Drain Pump
If neither a clogged drain hose nor a blocked air gap seems to be causing your dishwasher’s drainage problem, there may be an issue with the drain pump itself. The drain pump is responsible for pumping out the wastewater from your dishwasher. If it becomes faulty or worn out, it won’t be able to remove the water effectively. To troubleshoot this, start by locating the drain pump, typically found at the bottom of your dishwasher. Check if there are any visible signs of damage or if it’s making unusual noises when you run a drain cycle. If so, you may need to replace the drain pump to fix the issue.
Drain Impeller Blockage
Sometimes, a dishwasher not draining can be attributed to a blockage in the drain impeller. The drain impeller is a small component that helps move water through the drain system and out of your dishwasher. Similar to other parts of your dishwasher, it can get clogged with debris like food particles or broken glass over time. To address this problem, you will need to remove the lower spray arm and access the impeller underneath it. Clean any debris that you find using a soft brush or cloth and ensure that it spins freely without any obstructions.
In conclusion, a dishwasher not draining can be caused by various factors such as a clogged drain hose, blocked air gap, faulty drain pump, or a blocked drain impeller. By following these simple troubleshooting steps and implementing appropriate solutions, you should be able to resolve most drainage issues with your dishwasher on your own. However, if none of these remedies work or if you are unsure about performing any repairs yourself, it’s always best to consult a professional appliance technician for further assistance.
