A washing machine that keeps draining even when it’s turned off can be confusing and frustrating. With Whirlpool top-load washers, this unusual behavior is often linked not to the pump itself, but to the control board.
Understanding the Problem
In this case, the washer’s drain pump continued to run nonstop, even when the machine was powered off. At first glance, it might seem like a stuck relay or a failing drain pump. However, experience shows that when a pump receives constant power, the real issue is usually higher up in the system.
Why the Control Board Matters
The control board acts as the “brain” of the washer, sending signals to all major components, including the drain pump. When the control board fails, it can incorrectly supply power to the pump, causing it to run continuously regardless of the selected cycle or power state.
The Repair Process
After confirming that the pump itself was mechanically sound, the control board was identified as faulty. The repair steps included:
- Disconnecting power to the washer
- Removing and replacing the defective control board
- Reassembling the unit and restoring power
Once the new control board was installed, the washer immediately returned to normal operation.
Final Outcome
After replacement, the drain pump only activated when required during the wash and spin cycles. The washer now turns off properly, with no unexpected draining.
Helpful Tip for Washer Owners
If your washer’s drain pump runs constantly:
- Do not assume the pump is bad right away
- Unplug the washer to prevent unnecessary wear
- Have the control board checked, especially if the issue persists with the washer turned off
Catching control board issues early can prevent pump failure and help extend the life of your washer.
