This can cause the impeller to be blocked preventing it from spinning. The impeller is a small fan blade located in side of the drain pump. The impeller spins at a high rpm creating a tornado effect with the water. This causes the water to quickly exit the machine through the drain hose. The impeller is usually blocked by coins, pins and other small items that infiltrate through the filters which are suppose to prevent this from occurring. The drain pump on most front loaders is located in the front just below the door. To gain acees to the pump, you will have to remove the bottom acces panel. This is located at the bottom of the machine an is usually secured by 2 to 3 screws at the bottom of the panel. Tilt the washer back allowing it to rest on the wall. This will make it easier to remove the screws. Removing the screws will require a tool called a torx or a nut driver. Once the panel is removed the pump is directly in the front center.
There is a center large cap that screws out this will open the pump. Be prepared with towels or even better a wet/dry vac to collect the water. After removing the cap there is a small hole inside on the right wall of the pump. This is where the impeller is located. Make sure the machine is unplugged. with your finger spin the impeller blade making sure there isn’t any obstructions. Plug the washer up put the timer on a spin/drain cycle listen to hear the pump. If the pump is heard then in the small hole where the impeller is located place the tip of a plastic straw in the hole to ensure the impeller blade is spinning. If spinning you will hear the blade hitting the straw if not the blade is damaged and you will have to replace the pump. This can be done by removing the hoses ensuring that the hoses are properly returned on the pump housing and making sure all of the hose clamps are properly secure. This not a difficult job for a DIY project but it can be a little challenging making sure the pump rear hose is secure. I would recommend hiring an appliance repair company if you are not comfortable with replacing the pump, because this can cause leaks if the hose is not properly secure.
