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 - 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

If the above actions do not uncover the fault:
