If the machine fills with water but the drum does not turn, the drive system is the likely cause. Belt drive machines use a motor with carbon brushes and a drive belt, while direct drive machines from LG and Samsung use a brushless motor controlled by an inverter board.
We test the full drive system to find the failed part, then repair or replace only what is needed.

How long do carbon brushes last?
Usually five to ten years depending on use. When they wear down, the motor loses power and eventually stops. Replacing them is a quick and affordable repair.
