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.
• Larger 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)
• New drum hole pattern to cause as little wear as possible on clothing.
• New agitators that improve the wash process.
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:
• Move the load towards the smaller, gentler holes
in the middle of the drum.
• Move larger objects, such as grit, towards the
larger holes at the edges of the drum.

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.
• Ask the customer to describe the problem.
• Check whether the customer’s description matches any service code.
• Check that the machine is correctly installed:
- Electrical connection - Drainage
- Water connection - Machine correctly levelled
Fault found?
Incorrect installation or external factors that affect performance and functionality (for
example, water pressure, electrical supply, drainage).
The machine operates normally. No deviations can be found. The customer probably needs
to be informed about proper use of the machine. If necessary, also inform the customer
about the guarantee conditions and the fact that the customer will be charged for the
callout.
Yes
Open the service menu:
1. Check the settings
2. Run a test cycle
3. Note any fault codes
If the above actions do not uncover the fault:
• Conduct general troubleshooting. Use the documentation available at ServiceSaver
(service manuals, service memos, wiring diagrams and other documents).
