General product information

In conjunction with the introduction of the WM70.C (August 2010), our washing machines have
been altered in a number of areas. Here we present the changes to the wash drum and wash
agitators.

s,ARGERWASHDRUM

- 60 litres (previously 50 litres)

- 23 mm deeper, the drum is now 343 mm deep in total (previously 320 mm)

- 30 mm larger diameter, 480 mm in total (previously 450 mm)

All cylinder holes flanged to reduce wear on
textiles.

Area with large holes (3.7 mm) to remove
larger objects, such as grit.

Area with smaller holes (2.2 mm) to reduce
wear on textiles.

The angle of the edge of the cylinder, combined
with the shape of the agitators, moves the load
towards the middle of the drum. This improves
drum balance and reduces wear on textiles.

Hourglass-shaped agitators:

Troubleshooting strategy

At Asko, we believe in always remaining focused on the customer, and as an ASKO service
technician, you are one of the most important ambassadors of our brand. As such, it is important
that the customer finds the service callout a pleasant experience. Troubleshooting is an important
part of the service callout, and as such we have drawn up a troubleshooting strategy that
describes, in broad terms and step by step, what you need to do to find and diagnose faults.
