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 arising
in our machines.
