When a washer makes a buzzing sound, the most common fault is that there is something stuck in the pump and blocking it. The buzzing sound occurs as the drain pump tries to run but something is blocking it and the “buzzing” noise occurs. As a blocked pump is the most probable cause for a buzzing washer, there can also be a other problems that can cause this noise. We will list the most common reasons for this problem beginning with the most probable first. If your washing machine is NOT buzzing but instead your washer is not spinning or draining during the cycle, then a different troubleshooting method is needed.
MOST PROBABLE REASONS FOR A BUZZING SOUND IN WASHING MACHINE:
- Blocked Drain Pump: An object has lodged itself inside of the drain pump. There can be items such as a small sock, a coin, a toothpick, or something small in your clothes pockets when you wash them. These items can fall out of the pockets and end up in the drain pump causing it to become blocked and make the buzzing noise you hear. Here is an audio recording of a blocked drain pump. Unfortunately, the only way to fix this problem is to take the washing machine apart and open up the pump and remove the object causing the buzz sound. To find directions to take your specific washing machine apart, do a Google search for Make and Model of your washer.

This usually means your washing machine is old and the motor has died from old age.
