The unit sometimes will pause during Sanitize, or Pure Cycle, wash modes and appear not to be functional. The Sani-
tize and Pure Cycle wash cycles have target temperatures to assure washer performance. If the water temperature
doesn't meet the target temperature during the wash cycle, the washer will automatically add extra time to allow the
heater to bring the water up to the programmed, or target temperature. In this stage, the displayed time will pause and
hold until the heating operation has been completed. It is at this point that the customer may feel that operation has
stopped. (The maximum added programmed time is 30 minutes)
