Whirlpool AMERICAN HEAVY DUTY LAUNDRY PRODUCTS W10131548B - Manual (Page 5)

Choosing the correct detergent
To obtain excellent wash results, it is advisable to use a product that
is specially designed for top loading washing machines rather than a
product that is used in front loading automatic washing machines.
How to get the best results
Sort your clothes according to the garment labels or fabric type.
Test articles for colour fastness if they have no wash code. If you
mix fabrics, use the programme for the most delicate garment.
Dispensing the detergent
First select the load size, fill temperature, and programme start
position – see machine instructions. Pull out the timer knob to start
the programme, and let the tub start to fill with water. Open the lid
and sprinkle the detergent directly into the water. When the agitator
starts, it will quickly disperse the detergent into the water and ensure
that it is properly dissolved. Add the laundry by dropping each item
into the water while the agitator is working. This will ensure that the
laundry is evenly spread around the tub and will give you better wash
results. Do not overload the tub. When all the laundry is loaded, close
the lid and the machine will complete the wash, rinse, and spin cycles
automatically.
