Troubleshooting strategy

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.
• Ask the customer to describe the problem.
• Check whether the customer's description matches the reported fault.
• Check that the machine is correctly installed:
- Electrical connection
- Water connection
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 warranty conditions and the fact that the customer will be charged
for the service call.
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).
