Sometimes, small objects or articles of clothing can get caught in the drain pump. To determine if anything is blocking the drain pump, remove the drain pump and check the pump for obstructions. If the drain pump is clear of obstructions, but is still noisy during the drain cycle, replace the drain pump.
Clogged Pump or Hose
Sometimes, socks and other small articles of clothing can get into the drain system and clog the pump hose or the pump itself. Remove the hoses from the pump and check for any obstructions.
