13 Troubleshooting

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.
The manual includes a table of error messages that can appear on the
display(1 3.2 "Troubleshooting table for general errors").
•Warnings on the display
The warnings (13.4 "Displayed warnings") can also apply to the solar
heating system.
