Good afternoon, Claudio Persson. Eastern transmission boxes generally follow the same design. The key is when the brake arm must be pulled so that the centrifugal drum can make short shifts in one direction if there is only one plastic gear on top of the pulley of the transmission case or in both directions of having two gears of that area in the washing and rinsing stages. In the washing and rinsing stages and unlike the spinning stages, the centrifugal drum in order to be able to move in the opposite direction to the impeller is necessary that the following requirements are met: 1.-The brake arm must be pulled by the engine drain or motor torque minimum so that the brake band separates from the casing of the transmission box scarce a few microns in view of the maximum separation distance is only of a couple of millimeters. 2.-Presence of water in the plastic tub at any of its levels. Without water the spinning drum will not move. 3. That the impeller turns to inject jets of water to the inner columns of the centrifugal drum to make it always turn in the opposite direction to the rotation of the impeller. The spring of either a guide or two guides (as the case may be) in the washing and rinsing stages does not cling to the steel cylinder and that is why physically the spinning drum does not move as it does in stages of the centrifuge. Covenant on this. Thanks and regards.
