A washing machine that won’t drain properly is more than just an inconvenience — it can leave your laundry soaked, create foul odors, and even cause water damage. Whether the problem is a simple clog or a deeper plumbing issue, understanding the possible causes will help you solve it faster and avoid future headaches.

Common Reasons a Washing Machine Doesn’t Drain Properly

Clogged Drain Hose
Over time, lint, debris, and small objects can build up in the hose that carries water out of the washer, preventing proper drainage.
Blocked Pump Filter
Most washers have a small filter that catches debris. If it’s full, your washer may struggle to drain completely or stop mid-cycle.
Faulty Drain Pump
The pump is responsible for pushing water out. If it’s malfunctioning, you may hear strange noises or notice water left inside the drum.
Improper Drain Height
If the drain hose is installed too low or too high, it can cause backflow or slow drainage. A plumber can adjust the height to meet the manufacturer’s specifications.
Drain Pipe Clog in the Wall
Sometimes, the problem isn’t with the washer but the home’s plumbing. A clogged or partially blocked drain pipe can slow down or completely stop drainage.

Simple Fixes You Can Try First

Check and straighten the drain hose to avoid kinks or sharp bends.
Clean the pump filter, refer to your washer manual to locate it.
Run an empty cycle with hot water and vinegar to break down detergent buildup.
Make sure your washer is level an uneven surface can affect drainage performance.

If the issue persists, it’s time to call a plumbing professional.
