On washers with "Sani Cycles" or heated wash/rinse, the time on the cycle
often starts counting down after the proper temperature has been reached.
If the machine filled with 100F water, it will run without counting down the
time until the temperature reaches 140F. Therefore, the cycle can vary
greatly depending on the circumstances.
