10 Troubleshooting
10.1 Introduction A distinction is made between:
• General errors
General errors are not reported on the display. General errors are:
- Gas smell
- Display does not light up
- Insufficient or no hot water.
- Water leakage
- Explosive ignition
Table 10.1 gives a troubleshooting overview for general errors.
• Displayed errors
Errors are reported on the display, as follows:
- Line 1: An error code and its short description. The code is made up
of a letter and two digits.
- Lines 2, 3 and 4: a long description, and a recommended action,
alternating every 2 seconds. See Figure 10.1 and Figure 10.2.
The displayed errors are divided into two groups:
There are various types of errors:
- LOCK OUT ERRORS
When the cause is no longer present, these errors require a reset with
the R button, before the appliance can resume running.
- BLOCKING ERRORS
These errors disappear automatically once the cause of the error has
been removed, after which the appliance resumes by itself.
Table 10.2 gives a troubleshooting overview for the errors that appear on the
display.
