Washing appliance and associated method

A washing appliance having a circulation pump for circulating a washing fluid in a tub portion, comprising:

• a monitoring device configured to be capable of monitoring a condition of the washing fluid circulated within the tub portion;
• and
• a control device in communication with the monitoring device and configured to direct execution of one of a plurality of automatic wash programs by the washing appliance, each automatic wash program including a plurality of serially-conducted wash cycle segments, the wash cycle segments including at least one pre-wash cycle segment and a main wash cycle segment during which the circulation pump circulates the washing fluid, the control device being further configured to:
• direct the monitoring device to monitor the condition of the washing fluid at a plurality of predetermined discrete instances whereby the circulation pump is paused for a predetermined time period during, and prior to the completion of, the at least one pre-wash cycle segment of the executed wash program, wherein each predetermined discrete instance occurs at a predetermined time during the at least one pre-wash cycle segment;
• direct an alteration of the washing fluid in response to the monitoring device determining that the condition of the washing fluid exceeds a threshold, wherein the alteration of the washing fluid further comprises at least a partial draining and refilling of the washing fluid in the washing appliance prior to the completion of the at least one pre-wash cycle segment;
• and
• direct wash water from the at least one pre-wash cycle segment to be at least partially carried over to the main wash cycle segment in response to the monitoring device determining that the condition of the washing fluid does not exceed the threshold.

A method of controlling a washing appliance having a circulation pump for circulating a washing fluid therein, comprising:

• executing of one of a plurality of automatic wash programs in the washing appliance, each automatic wash program including a plurality of serially-conducted wash cycle segments, with the wash cycle segments including at least one pre-wash cycle segment or at least one post-wash cycle segment during which the circulation pump circulates the washing fluid;
• monitoring a condition of the circulated washing fluid at a plurality of predetermined discrete instances whereby the circulation pump is paused for a predetermined time period during, and prior to the completion of, the at least one pre-wash cycle segment and/or the at least one post-wash cycle segment of the executed wash program, wherein each predetermined discrete instance occurs at a predetermined time during the at least one pre-wash cycle segment and/or the at least one post-wash cycle segment;
• and
• altering the washing fluid in response to the condition of the washing fluid exceeding a threshold.
