clothes are still soaking wet at the end of the cycle, it's not spinning fast enough.

Diagnosis

The LG WM3600HWA utilizes a sophisticated "Automatic Balance" system that monitors the drum's oscillation via a hall sensor on the motor. When the machine detects that the load is clumped on one side—often caused by heavy items like towels or bedding wrapping around a single heavy garment—it will intentionally skip the high-speed spin (1200 RPM) and drop to a low-speed "tumble" or "drain" mode to prevent the machine from walking across the floor or damaging the outer tub. This is a safety mechanism, not a mechanical failure. You can confirm this is an imbalance issue if the timer seems to "hang" or count backward for several minutes during the final stages of the cycle. If the drum rotates slowly but the clothes remain saturated, the machine is likely stuck in a "sensing" loop, attempting to redistribute the load before it feels safe enough to ramp up to full speed. If the machine is completely silent and doesn't spin at all, the issue is likely a failure in the drain pump or the door lock assembly, as the machine will not spin if it detects water is still in the tub or the door is not securely latched.

How to Fix It

To resolve an imbalance and force the machine to reach maximum extraction speed, follow these steps:

1. Press the Power button to turn off the machine and then press it again to restart.
2. Open the door and manually redistribute the laundry. If you have a single heavy item (like a large bath mat or a heavy duvet), add two or three smaller towels to the opposite side of the drum to create a counterweight.
3. Ensure the drum is not overfilled. The laundry should occupy no more than 3/4 of the drum volume; overcrowding prevents the clothes from shifting into a balanced ring during the spin phase.
4. Close the door firmly until you hear the click of the lock.
5. Press the Power button and then the Power/Cycle selector. Instead of running a full cycle, press the "Spin Only" button.
6. Press the "Spin" button repeatedly to cycle through the speed settings until "High" or "Extra High" is selected on the digital display.
7. Press Start/Pause. The machine will now perform a dedicated high-speed extraction to remove the excess water.

If That Didn't Work

• Clean the Drain Pump Filter: If the pump is partially clogged with lint, coins, or hair, the machine cannot evacuate water fast enough to trigger the high-speed spin. Open the small access door at the bottom left of the front panel. Place a shallow tray under the small drain hose, pull the plug to empty the remaining water, then unscrew the large circular pump filter counter-clockwise. Remove any debris, rinse the filter under warm water, and screw it back in tightly.
• Level the Machine: If the machine is tilted, the internal sensors will trigger an "uE" (Unbalanced Error) even if the clothes are distributed. Place a bubble level on top of the machine. If it is uneven, use a wrench to adjust the leveling legs at the bottom. Rotate the legs clockwise to lower them or counter-clockwise to raise them until the machine is perfectly level from front-to-back and side-to-side. Lock the jam nuts against the frame to prevent shifting.
• Check the Drain Hose: Ensure the corrugated drain hose is not kinked or pinched against the wall. If the water exits too slowly, the pressure sensor (water level switch) will tell the control board that the tub is still full, which prevents the motor from entering the high-RPM spin phase for safety reasons.
• Inspect the Door Lock Assembly: If the door lock is failing or the strike pin is worn, the machine may lose the "locked" signal momentarily. This immediately kills the spin cycle. Inspect the lock for any burnt plastic or loose wiring. If the "Lock" icon on the display flickers during the cycle, the lock assembly needs replacement.

Heads Up

• Avoid washing a single heavy item (like one large rug) alone; always pair heavy items with other textiles to maintain centrifugal balance.
• Run a "Tub Clean" cycle with a dedicated cleaner every 30 cycles to prevent biofilm buildup in the pump filter, which can slow down drainage.
• Never use more than 2 tablespoons of HE detergent; excess suds create a "cushion" in the drum that tricks the balance sensor into thinking the load is uneven, causing the machine to skip the high-speed spin.
• Check the shipping bolts if the machine was recently moved; if they weren't fully removed, the tub cannot suspend properly, leading to constant imbalance errors.
