Detection Of Inner Bowl Float Off Point – Bowl Check

During fill the inner bowl will rotate to ensure that the clothes are evenly saturated with water. When the chosen water level is reached, and before the agitate cycle is started, Smartdrive will carry out inner bowl float checks, (bowl check). The inner bowl will stop and commence a number of small agitate type actions. During this action Smartdrive determines if the inner bowl has floated. If it has, Smartdrive will determine the required water level and check if the operator has selected the correct level. If the inner bowl has not floated off, Smartdrive will continue filling and check again later. The water level at which the inner bowl floats off is not necessarily the same as the final water level.

Detection of Inner Bowl Re-Engagement – Bowl Check

After Smartdrive has pumped out the water, the inner bowl will sink down and re-engage onto the drive spline. To ensure the inner bowl has re-engaged correctly, Smartdrive will carry out a bowl re-engage test sequence, (bowl check). Bowl check consists of a series of short agitate type actions before the spin cycle starts. A sound may be heard as the inner bowl re-engages. The following fault codes are associated with bowl check 40, 47, 56 and 160.

Balance Rings

The inner bowl has 2 balance rings, one at the top, and one at the bottom. These are sealed compartments half full of water. This water allows the bowl to balance. If these rings are empty the inner bowl must be replaced.

Lint Removal System

The self-cleaning lint removal system works by continuous water circulation, resulting in the separation of lint from the wash water. As a result of the agitator action, lint and wash water are sucked into the agitator stem and down to the base, where they are directed into the cavity between the inner and outer bowls. The extruded holes of the inner bowl are shaped to allow the wash water to flow back into the bowl, but prevent the lint from following.

The lint then floats to the surface of the water, between the inner and outer bowls and remains there until it is flushed out the drain at the end of the wash cycle. In the spin mode, water spun from the clothes through the small holes in the bowl flushes the lint off the outer bowl and down the drain. The self- cleaning lint removal system has proved to be effective and efficient and should require no maintenance.
