The washer's time display may differ from the times printed in the owner's manual.
The time remaining to the end of the wash cycle is an approximation. Factors that contribute to the difference in cycle completion times include:
Water supply pressure
Temperatures which vary from location to location and from season to season (summer to winter)
Unbalanced loads - If the clothes in the drum are an unbalanced load, the drum will continue to turn slowly until the laundry load is balanced adding extra time to the wash cycle.
