The LG washing machine error code nD means the washer failed to drain water from the drum within the required time limit — the water level did not drop to the expected point before the cycle timed out. Start by checking the drain hose for kinks, clogs, or incorrect installation height. If the hose is clear, a blocked pump filter (coin trap) is the next most likely cause and is the easiest DIY fix. If the code persists after all external checks, the drain pump itself has likely failed and will need a technician to diagnose and replace.
The LG washing machine error code nD stands for No Drain. It appears when the washer's control board attempts to pump water out of the drum during or at the end of a cycle, but the water level sensor does not detect the expected drop in water level within the allotted time window. When the drain timer expires with insufficient drainage detected, the machine halts the cycle and displays nD to alert you.
On some LG models the code appears in lowercase as nd, or with a space as n D, but all three refer to the same drain failure fault. The nD code is closely related to the OE (Output Error / Drain Error) code found on other LG washer generations — they describe the same problem using different notation depending on the model series.
Unlike a fill error, a drain failure leaves the drum full of water with wet laundry inside. Because the most frequent causes are outside the machine — at the drain hose routing or the accessible pump filter — start your diagnosis there before assuming the drain pump itself has failed. In many cases, a clogged coin trap or a kinked drain hose is all that stands between you and a resolved error code.
Press the power button to cancel the current cycle, then unplug the machine from the wall outlet or switch off its dedicated circuit breaker. This clears the error state and is the safe starting point before any physical inspection.
Pull the washer away from the wall enough to see the drain hose along its full length. Straighten any sharp bends or flat sections. Disconnect the hose from the standpipe and check for a clog by running water into its open end from a bucket — if it flows freely, the hose itself is clear. If not, use a drain snake or flexible brush to clear the obstruction.
Place a shallow pan and towels on the floor in front of the washer. Locate the small access panel at the lower front of the machine and open it. Slowly unscrew the filter cap counter-clockwise — water will flow out, so have towels ready. Remove the filter completely and clear any lint, coins, hairpins, or debris from both the filter mesh and the filter housing recess. Rinse the filter under running water, then reinsert and hand-tighten firmly.
Pour a bucket of water directly into the standpipe or sink that the washer drain hose connects to. If it drains slowly or backs up, the household drain is the problem — not the washer. Clear the household drain before running another cycle.
Measure from the floor to the point where the drain hose exits into the standpipe or sink. It should fall between 24 and 96 inches (61 to 244 cm). If the hose is too high, lower the standpipe attachment point or reroute the hose. Secure the hose with a U-shaped drain hose guide bracket to prevent it from slipping or siphoning.
Plug the washer back in and select the Drain and Spin cycle. Stand nearby and listen for the pump motor running — you should hear a steady hum and water exiting through the drain hose within the first 30–60 seconds. If the cycle completes without nD, the problem is resolved.
If the code reappears after confirming the drain hose routing, pump filter, and household drain are all in order, the root cause is inside the machine. A failed drain pump, a defective water level sensor, or a faulty control board each require professional diagnosis and replacement. Do not continue running cycles — a drum that cannot drain puts excess stress on the motor and may damage clothing.
Work through the steps above first. Book a professional repair if any of the following apply:
When a Promix Appliance Repair technician arrives for an LG washing machine nD call, the first step is a live drain test to confirm whether the pump motor is receiving power and running, how much water is moving through the drain path, and what signal the water level sensor is sending to the control board as the drum empties. This diagnostic takes roughly 10 to 15 minutes and immediately tells the technician whether the fault is in the drain hose path, the pump itself, the pressure sensor, or the board.
In most nD cases where the filter and hose have already been cleared, the drain pump has failed or has debris jammed in the impeller. Promix technicians carry common LG drain pump assemblies on the truck, which means the majority of repairs are completed the same day without a return visit. If the pressure sensor, sensor hose, or control board is the cause, parts are sourced quickly and installed with a full warranty on parts and labor. Promix Appliance Repair brings over 10 years of LG appliance experience to every call. The service call fee is credited in full toward your repair if you proceed — you hear the price before any work begins, with no surprise markup.

Control board faults vary depending on which component has failed. The exact cost is only determinable after a live diagnostic. Call (781) 666-9565 for a transparent quote before any work begins.
No. When nD appears the washer has halted because it could not drain the drum within the required time. Starting another cycle will not help — the machine will stop again at the same point with the drum still full of water. Resolve the drain issue first, then restart. Running cycles without successful drainage puts unnecessary stress on the motor and can leave laundry sitting in standing water for extended periods.
A power reset — unplugging for 30–60 seconds and plugging back in — will clear the displayed code temporarily. However, nD will reappear as soon as the washer tries to drain again if the underlying problem has not been fixed. Use a reset only to confirm the code or to restart a Drain and Spin cycle after you have addressed the root cause.
They describe the same fault — the washer failing to drain — but appear on different LG model generations. OE (Output Error or Output drain Error) is used on older LG washer series, while nD (No Drain) is used on newer models. The causes and diagnostic steps are identical. If your machine shows OE, follow the same pump filter, hose, and standpipe checks outlined above.
First unplug the machine. Lower the drain hose below the level of the drum — ideally into a bucket on the floor — and allow gravity to drain as much water as possible. Then open the pump filter access panel at the front-bottom of the washer, place towels underneath, and slowly unscrew the filter cap to drain the remaining water into a shallow pan. This empties the drum so you can safely remove the laundry before diagnosing the fault.
If the cause is a clogged pump filter or a kinked drain hose, the fix typically takes 15 to 45 minutes. If the drain pump has failed, a Promix technician can usually complete the replacement in about 60 to 90 minutes during the same visit, since common LG drain pump parts are carried on the truck. Sensor or control board faults may require a return visit depending on parts availability.
LG's standard limited warranty covers manufacturing defects — including a failed drain pump or a defective water level sensor — if the washer is within the warranty period. Problems caused by external factors such as a clogged pump filter, a kinked drain hose, or a blocked household standpipe are not covered, as they are not appliance defects. Check your warranty documentation or contact LG directly to confirm coverage for your specific model and purchase date.
With the filter and hose confirmed clear, verify that the drain hose exit height is between 24 and 96 inches from the floor, and pour water directly into the standpipe to confirm the household drain is not backing up. If all three pass and nD persists, the drain pump has most likely failed — either the motor has burned out or there is debris jammed in the impeller. At that point, professional diagnosis is necessary.
