LG Washer Won’t Drain / Keeps Draining

Dealing with a malfunctioning LG washer can be quite a hassle, especially when it refuses to drain or won’t stop draining. I recently faced this issue with my own machine, turning laundry day into a troubleshooting session. Through this experience, I learned not only the common causes of these issues but also some effective solutions, which I’m eager to share with others facing similar washer woes.

If your LG washer won’t drain or won’t stop draining, a clogged drain pump filter could be the culprit. Over time, lint, small items, and debris can accumulate in the filter, obstructing water flow. To fix this, locate the drain pump filter on the front lower panel of your washer, remove it, and clean out any debris. Regularly cleaning the filter can prevent future drainage issues.

Another reason for drainage problems could be a malfunctioning drain pump. If the pump is damaged or has an electrical fault, it may fail to effectively remove water from the washer. In this case, the drain pump may need to be inspected and potentially replaced. This is a more complex repair and might require professional assistance, especially if you’re not familiar with appliance repair.

Clogged Hose Pipe or Pump

Small particles of dirt/plastic and sock can find a way inside the drainage system and clog the hosepipe or pump. The solution is to remove the hose from the drainage pump to check for obstruction and remove particles causing the clogging.

Faulty Switch Assembly and Door Lock Engine

The washing machine’s door remains shut during all cycles of operation. The door lock secures it. The washer starts operating once the door is shut. But if it remains open, the switch is likely to prevent the machine from working. The problem starts when the washer door lock becomes defective, making it fail to spin clothes or start. This problem may be due to mechanical or electrical failure.

If there are faults with the door lock and it fails to latch properly, you need to get a replacement. If there is any switch without continuity, get a replacement.

Water Pump Girdle Default

Some old versions of LG washers have a water pump girdle. Damaged or worn water pump girdles prevent the washer from draining. Check the girdle for excessive wear and replace it immediately if you come across any faults.

If your washer gets filled up with water but keeps draining, observe its cycle carefully to identify the cause. This will also help you know where to fix it and if you can fix it. It is most likely an issue with the plumbing or the pump.

Faulty Drain Pump

When the water comes in through the inlet valve, the water will immediately get siphoned out if the drain pump is stuck open. Also, it could be jammed with an object or clothing, causing it to remain open. Unclog your drain pump or replace it.


If the washer does not sense that water keeps draining, it will keep rinsing or washing before there is enough water. Siphoning is when your LG washer gets stuck in this cycle, causing more water to keep coming in. It is caused when the level of water is higher than the end of the drain hose. Check your hose or drain pump to ensure that they are not jammed. If the drain pump is not working, test it using a multimeter, and replace it.

If your drain pump keeps running yet the water is being pumped out, this could be an issue with overfilling. Your washer may be unable to sense when to stop running. Your washer should display an error code when there is a fault, and it cannot abort the cycle. This does not necessarily mean you need a new washer or an expert plumber to do the fixing. Some of the defects can be repaired at home, as long as you know how to go about it.

In this case, there are few likely causes: your washer might be overheating, and the standpipe could be positioned wrongly. It will not be easy to tell which of the two is causing your problem unless you remove the front panel and check inside the machine.

Faulty Thermostat

A faulty thermostat will lead to overheating, causing the pump to become energized and drain water. This will start and stop the cycle multiple times for the pump to energize. If an overheat error is displayed or you suspect it is the problem, test the thermostat to ensure it is working. If not, get a replacement.

Incorrect Position of the Standpipe

The standpipe in your LG washer is plumbed into the drain hose. It should have a U-bend, a hook shape, and Drain Outlet Hose Hook. This prevents the drain hose from being pushed far to the bottom or falling out. When the standpipe is wrongly positioned, the drain hose is lowered, causing siphoning when the drain pump keeps running. Check how it is positioned and fix it.

Final Thoughts

Your LG washer is meant to make your life convenient by doing the washing for you. However, this convenience is sometimes disrupted by a faulty drain system, which can result from several factors.
