Have a Roper direct driver electric washer, that will agitate, and spin, but won't drain. Am somewhat familiar with this model of Roper/Whirlpool, so I take it apart. All hoses clear, pump and motor spin freely. All fins on pump impeller intact (from what I can tell).
Acts normal, other than the fact that at the end of the entire wash cycle, there's still a FULL tub of sudsy water.
