process 100 is independent of the method by which the existence of suds lock is determined several methods can be applied in order to ascertain the existence of suds lock fig4 a displays a block diagram 108 of the automatic washer containing recirculation hardware where a measure based on the flow rate of the wash liquid recirculation line is used to ascertain when water is added to the recirculation system the flow rate can be measured in one of a number of known ways a flow washer 68 contained in detergent dispenser valve 63 controls 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 shown in a block diagram 110 in fig4 b to determine when water needs to be added to the system can be performed by any of various techniques capable of measuring the.
