Concrete Counterweight: The large grey block on top of the drum helps stabilize the machine during high-speed spinning. If the machine is shaking excessively, check this for cracks or loose mounting bolts.Suspension Springs: The metal springs (visible on the right) support the weight of the drum and dampen movement. Inspect these for stretching, rust, or damage.Electronic Control Board: The detached panel on the right contains the main electronics. If the machine won't start or shows errors, this board or its wiring may be faulty.
