My Beko washing machine is taking longer to run washing programmes than the manual states - is this a fault?

The times specified in your user manual are average values and will not be accurate for all washes. This is because there are many variables that can affect the length of a washing cycle, such as the selected temperature, water pressure and hardness, and the type and amount of laundry being washed. Also, programme times are extended if the appliance needs to redistribute an unbalanced load or add extra rinses if excess foam is detected.
