  2. Locate the pump filter (usually behind a small hatch at front bottom) and remove it cautiously, catching any water.
  3. Clear visible debris (lint, coins, small objects) from filter and inspect the drain hose for kinks or clogs.
  4. Replace the filter and reconnect any hoses, then test a short drain cycle.
