Understanding the Problem

If your LG WM2101LW fills with water but won't drain or complete the spin cycle, the problem is usually with drainage or the washer’s ability to detect that the tub is empty. A washer that won’t drain will often skip the spin stage, because the machine’s control logic prevents high-speed spinning when water is still present. The most common root causes are a clogged or failed drain pump, a blocked drain hose, a defective door lock/door latch (front-load models), or an electronic/control issue that prevents the washer from advancing cycles. This guide helps you narrow the cause, verify the faulty component, and points to the parts that commonly fix the problem.

Common Symptoms

Washer fills but does not pump out water; cycle ends without spinning; loud humming from the machine during drain attempt; error codes related to draining (check your display).

Common Causes

  • Clogged or mechanically failed drain pump preventing water removal
  • Blocked or kinked drain hose or external plumbing obstruction
  • Faulty door lock (front-load) or lid switch (top-load) preventing spin cycle

Helpful Repair Tip

Before replacing parts, check for visible clogs: remove the filter/access cover (if present) and inspect the drain pump inlet and drain hose for debris, coins, or fabric that can block flow.

Frequently Asked Questions

How can I tell if the drain pump is bad or just clogged?

Listen during the drain attempt: a humming or buzzing noise with no water movement often indicates the pump is getting power but the impeller is jammed or the pump is mechanically failed. If the pump makes no sound at all when it should be running, it may not be receiving power (control issue) or the pump motor is dead. Inspect the pump inlet and the removable filter (if present) for debris before replacing the pump.

Can I fix a 'won't drain' problem myself and how much will parts cost?

Many drain problems are DIY-friendly: clearing a blockage in the filter or hose can be done with basic tools. Replacing a drain pump or door lock is moderate difficulty — expect 30–90 minutes if you're comfortable with unplugging the washer and removing panels. Parts typically range: drain pump $40–150, door lock $30–90, control board $100–400. Always verify the exact OEM part number from your washer’s model/serial label before buying, and unplug the appliance before attempting repairs.
