Since you've already checked the pump, hoses and motor, here are some additional issues to look at:1. Faulty timer:
Does your machine fill with water and begin agitating, but the cycle never advances far enough to allow the water to drain? The timer that controls the cycles may be broken. Arrange for washing machine repair service.2. Worn or loose belts:
Are clothes still soaked at the end of a wash, even though the washing machine appears to go through the spin and drain cycles? The timer that controls the cycles may be broken. This is a job for the pros.3. Faulty or jammed internal impeller on pump:
When the spin cycle starts, do you hear a humming noise? The internal impeller that moves the water through the drain pump may be faulty or jammed. A grinding or grating sound is almost always an indication of a coin, button or other object colliding with the impeller. Have a washing machine repair expert determine if the impeller is jammed and can be cleared, or if the pump needs to be replaced.
