FAQ
How do I know the pump is bad?
If the filter and hose are clear but the washer still hums and will not drain, the pump is a strong suspect.
Can a clogged filter cause the same symptoms?
Yes. Always clean the filter before replacing the pump.
Does pump failure affect spin?
Yes. The washer may not move into a full spin until water has drained.
Should I replace the hose at the same time?
Only if it shows damage, blockage, or clear wear.
