Not Draining Properly

Reasons For Poor Drainage

There can be several reasons why your LG dishwasher is not draining properly. Understanding these reasons will help you troubleshoot the issue efficiently:

  1. Clogged filter: Food particles and debris can accumulate in the filter, blocking the flow of water. To check if the filter is clogged, remove it and rinse it under running water.
  2. Kinked drain hose: The drain hose may become twisted or kinked, obstructing the water flow. Inspect the drain hose for any bends or obstructions and straighten it if necessary.
  3. Blocked drain hose: Over time, the drain hose can accumulate debris and become partially or fully blocked. To unclog it, disconnect the hose and use a long, flexible brush to remove any obstructions.
  4. Defective drain pump: If the filter and hose are clear, the issue might lie with a faulty drain pump. This can prevent the water from draining properly. In this case, you may need to replace the drain pump.

How To Unclog The Dishwasher Drain

If you’ve determined that the poor drainage is caused by a clogged dishwasher drain, here are the steps to unclog it:

  1. Turn off the dishwasher: Before starting any troubleshooting, make sure to turn off the dishwasher and unplug it from the power source.
  2. Access the drain: Locate the drain at the bottom of the dishwasher. It is usually covered by a grate or panel. Remove the panel carefully to access the drain area.
  3. Remove debris: Use a sponge or paper towel to remove any visible debris from the drain area. Be careful not to push the debris further into the drain.
  4. Use a vinegar and baking soda solution: Mix equal parts of vinegar and baking soda to create a bubbling solution. Pour it down the drain and let it sit for about 15 minutes. The fizzing action will help break down any remaining debris.
  5. Flush with hot water: After the solution has had time to work, flush the drain with hot water. This will help dislodge any loosened debris and clear the drain.
  6. Check the drain hose: While you’re unclogging the drain, also inspect the drain hose for any clogs or kinks. Straighten the hose if needed and remove any obstructions.
  7. Reassemble and test: Once you’ve cleared the drain and checked the hose, reassemble the dishwasher and plug it back in. Run a test cycle to check if the drainage issue has been resolved.
