Long Cycle Times Asko Washing Machines
Was doing some nosing around owner's manuals for older Asko units and the wash times for "Normal/Cottons" could hit >75 minutes. However there is a method to their maddness.
Again speaking of the older units Asko washers added time to wash cycles when lower wash temperatures were chosen and or for enzyme detergents. Both under the then accepted rules that lower wash temperatures required longer cycle times to compensate, and that enzymes worked well within the "low" temperature range of about 100F to 110F with increased contact time required for the best possible results.
Miele washers of the period also had something similar. My W1070's manual speaks of some system/programming that promises the same wash period regardless of temperatures chosen.
Older enzyme products did indeed require such conditions but modern products have moved on. Today's detergents/laundry aids with such things will work in cold, cool, warm and even slightly hot (120F), thus eliminating the need for long contact times, IMHO.
