Electrolux ELFW7637AW 4.0 cu ft Front Load Washer with Steam and Sanitize Cycle MECH-PUMP Error Fix: Drain Pump Clogged or Noisy

The drain pump makes a loud humming, buzzing, or rattling noise during draining, or drains slowly despite a clear drain hose. Small items (coins, hairpins, buttons, bra underwires) can pass through the filter and jam the pump impeller. Access the drain pump from the front-bottom of the washer. Remove the pump and inspect the impeller for foreign objects. Also check for sock fragments or lint buildup around the impeller. If the pump motor is burned out (no humming at all), replace the drain pump assembly.
