Unclog and drain your lg dishwasher in minutes: the ultimate fix!

If your LG dishwasher is not draining properly, it can be a frustrating inconvenience. Fortunately, there are several steps you can take to troubleshoot and resolve the issue yourself. This comprehensive guide will provide you with a step-by-step approach to identify and fix the problem, ensuring your dishwasher is back up and running in no time.

Identifying the Problem

Before you start troubleshooting, it’s important to identify the specific symptoms your dishwasher is exhibiting:

• Water pooling at the bottom of the dishwasher
• Dishes remaining wet or soapy after a cycle
• Dishwasher making unusual noises during draining
• Error codes or lights flashing on the control panel

Step 1: Check the Drain Hose

The drain hose is responsible for carrying wastewater away from the dishwasher. If it becomes kinked, clogged, or damaged, it can prevent the dishwasher from draining properly.

• Inspect the drain hose: Look for any visible kinks or blockages. Check both ends of the hose, where it connects to the dishwasher and the drainpipe.
• Clear any clogs: If you find a clog, try clearing it using a drain snake or a wet/dry vacuum.
• Replace the drain hose: If the hose is damaged beyond repair, you will need to replace it with a new one.

Step 2: Clean the Drain Filter

The drain filter is designed to trap food particles and other debris from entering the drain hose. Over time, it can become clogged, which can restrict water flow.

• Locate the drain filter: It is typically located at the bottom of the dishwasher, near the center.
• Remove the filter: Unscrew the filter cap and lift out the filter basket.
• Clean the filter: Rinse the filter thoroughly with hot water and scrub away any stuck-on debris.
• Reinstall the filter: Replace the filter basket and tighten the cap securely.

Step 3: Inspect the Drain Pump

The drain pump is responsible for pumping water out of the dishwasher. If it fails or becomes clogged, it can prevent the dishwasher from draining.

• Locate the drain pump: It is usually located at the bottom of the dishwasher, near the back.
• Check for clogs: Look for any debris or objects that may be blocking the pump impeller.
• Test the pump: Unplug the dishwasher and remove the drain hose from the pump. Pour a cup of water into the pump housing and plug the dishwasher back in. If the water is pumped out, the pump is working properly.
• Replace the drain pump: If the pump is not working, you will need to replace it with a new one.

Step 4: Check the Air Gap

The air gap is a small device installed on the countertop near the sink. It prevents wastewater from flowing back into the dishwasher.

• Inspect the air gap: Look for any clogs or blockages in the air gap.
• Clean the air gap: Remove the air gap cover and clean it with hot water.
• Replace the air gap: If the air gap is damaged or cannot be cleaned, it will need to be replaced.

Step 5: Reset the Dishwasher

Sometimes, a simple reset can resolve minor issues with the dishwasher.

• Unplug the dishwasher: Disconnect the dishwasher from the power outlet.
• Wait 30 seconds: This allows the dishwasher to completely reset.
• Plug the dishwasher back in: Reconnect the dishwasher to the power outlet and turn it on.

Step 6: Check the Control Board

The control board is the electronic brain of the dishwasher. If it malfunctions, it can affect the dishwasher’s draining function.

• Inspect the control board: Look for any visible damage or loose connections.
• Test the control board: This requires specialized knowledge and equipment. If you suspect a problem with the control board, it is best to contact a qualified appliance repair technician.

Wrapping Up

By following these steps, you can effectively troubleshoot and repair your LG dishwasher that is not draining. Remember to always unplug the dishwasher before performing any repairs. If you encounter any difficulties or the problem persists, do not hesitate to contact a professional appliance repair technician for assistance.
