13.1 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.
The manual includes a table with general
errors (13.2 "Troubleshooting table for general
errors").
• Displayed errors
Errors are reported on the display as follows:
- Line one: an error code and a brief
description. The code consists of a letter and
two digits.
- Lines two, three and four: a long description,
alternating with a recommended action. See
the figures. The first shows a possible error,
the second shows the appropriate checking
action.

There are various types of errors, all falling into
one of two groups:
- LOCK OUT ERRORS
When the cause has been removed, these
errors require a reset with the
button, before the appliance can resume
operation.
- BLOCKING ERRORS
These errors disappear automatically once
the cause of the error has been removed,
after which the appliance resumes operation
by itself.
