3.7 Wash Cycle 3.7.1 Tub The tub is the main cavity where all the wash activity occurs. The tub is a plastic recepticle which has a wash pump and sprayarm at the base. The tub also has guide vanes around its walls which direct falling water from the wash cycle in a clockwise direction around the filter plate. This clears the filter plate of food particles into the sump where they can be trapped or pumped out during the drain cycle. 3.7.2 Rotor The rotor is a four pole permanent magnet rotor w

3.11 Drying Cycle Immediately after water from the final hot rinse has been drained from the tub, the drying system begins operation. The fan draws air through the tub, where it absorbs water from the dishload. The moisture laden air is then mixed with a larger quantity of ambient air (from the kitchen), to minimise the amount of vapour visible when exiting from the drawer front. The fan runs continuously during the drying cycle and will restart if the tub is opened and closed again. After the
