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 ser vice 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.

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 Ser viceSaver (service manuals, service memos, wiring diagrams and other documents).
