the flow rate within a predetermined range for a variety of predictable inlet water pressures limiting flow in this manner allows the flow rate to be inferred based upon the on time of the inlet valve a flow meter may also be used finally the deep fill rate may also be discerned this intermittent process is due to the dry clothes load absorbing water into the load and thus the system requiring more water to regain the necessary flow rate a similar approach is shown in a block diagram 110 in fig4 b which shows that determining when water needs to be added to the system can be performed by any of various techniques capable of measuring the height of the wash fluid in the sump portion of the tub alternatively a pressure sensor may be used to determine whether one or more predetermined pressure levels have been reached in either case if the control determines that the necessary wash fluid amount recirculating within the washer is satisfied the control discontinues adding water by intermittent closing of the water inlet valve using either of these means shown in fig4 a or 4 b to control the process of adding water to the system an alternating pattern of the times for the addition of water to the system and not adding water to the system can.
