A washing machine that refuses to drain can leave you with soaking wet clothes and plenty of frustration. Before spending money on a new appliance, consider a simple repair that can save both time and cost. A faulty drain pump motor is often the reason behind drainage problems, and replacing it is a straightforward task that most people can do on their own.
This step-by-step guide explains how to replace the drain pump motor in your washing machine. With basic tools and about an hour of work, you can restore proper drainage and keep your washer running efficiently without calling a technician.
Why Replace the Drain Pump Motor
When a washer stops draining, the drain pump motor is one of the most common parts to fail. Though it may seem like a complex repair, the process is manageable with a little patience and preparation. By replacing the faulty motor yourself, you can avoid an expensive repair bill and extend the life of your machine.
Common Signs of a Faulty Drain Pump Motor
Before buying a replacement part, it helps to confirm that the pump motor is the real problem. Look out for these symptoms:
- The washer stops mid-cycle and leaves water inside the tub.
- You hear a humming or grinding sound coming from the lower front of the machine.
- The washer drains very slowly, even with no visible clogs in the hose.
- There is a burning smell during the drain cycle.
- The machine’s error codes point to a drain or pump failure.
- You notice small leaks underneath the washer during operation.
These signs often indicate that the pump motor is failing or has already burned out.
