FAQ
Why is my washer not draining even after cleaning the hose and filter?
If the hose and filter are clear, the drain pump might be faulty or the pump belt could be broken. Check for motor engagement or error codes.
Can I use a plunger to unclog a washer drain?
Avoid using a plunger, as it can damage the pump or push debris further into the system. Use a plumber's snake or wire hanger instead.
How often should I clean the drain pump filter?
Clean the drain pump filter every 3–6 months, depending on usage, to prevent clogs and maintain efficiency.
What if my washer is less than a year old and won't drain?
Check for manufacturer warranties and contact customer support. A new washer may have a defect or require professional service.
