If your LG dishwasher won’t drain, there may be an issue with the drain hose becoming kinked or clogged, preventing water from draining properly. Inspect the drain hose and straighten any visible kinks or remove any obstructions.
Make sure the hose is positioned correctly to allow water to flow freely. Alternatively, the drain pump may be faulty and need to be tested and replaced if necessary.
1. Clogged Drain Hose
If you’re experiencing drainage issues with your LG dishwasher, one possible culprit could be a clogged drain hose. The drain hose is responsible for carrying the wastewater out of the dishwasher and into the plumbing system. When this hose gets clogged, water can’t flow properly, leading to drainage problems.
1.1 Food Residue and Debris
One common cause of a clogged drain hose is the buildup of food residue and debris. Over time, small food particles and debris can accumulate in the hose, blocking the flow of water. To check for this issue, you’ll need to inspect the drain hose for any signs of blockage.
- Start by disconnecting the dishwasher from the power supply and turning off the water supply.
- Locate the drain hose, which is usually found at the back of the dishwasher or under the sink.
- If possible, remove the hose to inspect it more thoroughly. Look for any visible signs of blockage, such as food particles or debris.
- If you notice any blockage, use a long brush or a pipe cleaner to carefully remove it.
- Run water through the hose to ensure it is clear of any remaining debris.
1.2 Kinked or Bent Hose
Another possible issue with the drain hose is that it may be kinked or bent. When the hose is not properly aligned or has sharp bends, it can restrict the flow of water, causing drainage problems. Here’s how you can address this:
- Inspect the drain hose for any visible kinks or bends.
- If you find any, carefully straighten the hose to remove the obstruction.
- Ensure that the hose is properly aligned and doesn’t have any sharp bends.
- If necessary, adjust the positioning of the dishwasher to prevent the hose from getting kinked or bent.
By addressing a clogged drain hose, whether due to food residue and debris or a kinked/bent hose, you can often resolve drainage issues with your LG dishwasher. Remember to refer to your specific dishwasher model’s manual for detailed instructions and consult a professional if you’re unsure or uncomfortable with the troubleshooting process.
2. Faulty Drain Pump
Signs of a Bad Drain Pump
If your LG dishwasher is not draining properly, one of the possible causes could be a faulty drain pump. The drain pump is responsible for pushing the water out of the dishwasher after the cycle is complete. When this part malfunctions, it can result in water remaining at the bottom of the dishwasher or in other drainage issues.
Here are some signs that may indicate a bad drain pump:
- Standing water in the dishwasher: If you notice a pool of water at the bottom of your dishwasher after running a cycle, it could be a sign that the drain pump is not working.
- Noise during the drain cycle: If you hear unusual noises, such as grinding or buzzing sounds, while the dishwasher is draining, it may indicate a problem with the drain pump.
- Slow or incomplete draining: If the dishwasher takes longer than usual to drain or if it doesn’t drain completely, it could be due to a faulty drain pump.
How to Test the Drain Pump
If you suspect that the drain pump is causing the drainage issue in your LG dishwasher, you can perform a simple test to check its functionality. Here’s how:
- Disconnect the dishwasher: Before you begin any testing or repairs, make sure to turn off the power supply to the dishwasher and unplug it from the outlet.
- Access the drain pump: Locate the drain pump, which is usually located at the bottom of the dishwasher. Refer to the dishwasher’s user manual or manufacturer’s website for specific instructions on how to access the pump.
- Check for blockages: Inspect the drain pump for any clogs or debris that may be obstructing its function. Clear away any obstructions you find, such as food particles or foreign objects.
- Test the pump with a multimeter: Using a multimeter set to the resistance or continuity setting, test the drain pump for continuity. Place the multimeter probes on the terminals of the pump and check for a reading of zero or low resistance. If there is no continuity, it indicates a faulty drain pump that needs to be replaced.
- Replace the drain pump if necessary: If the drain pump fails the continuity test or if you suspect it is faulty, it’s recommended to replace it with a new one. Consult the dishwasher’s user manual or contact the manufacturer for guidance on the correct replacement part and installation process.
By following these steps, you can diagnose and address a faulty drain pump issue in your LG dishwasher. However, if you are unsure or uncomfortable performing these tests and repairs yourself, it is always recommended to seek professional assistance to avoid further damage to the dishwasher.
3. Blocked Drain Air Gap Or Sink Disposal
If your LG dishwasher won’t drain, one of the possible causes could be a blocked drain air gap or sink disposal. These components play a crucial role in ensuring proper drainage, and any blockage can hamper the dishwasher’s ability to drain effectively.
Checking for Debris
To determine if a blocked drain air gap or sink disposal is causing the drainage issue, you need to check for any debris that might be obstructing the flow of water. Here’s how:
