8 Errors
8.1 Introduction
A distinction is made between errors caused by the water heater and erros caused by
the dual service module. Errors caused by the water heater can be found in the
Installation-, User- and Service manual of the water heater. In this manual you will find
errors caused by the dual service module.
A distinction is made between:
 General errors
General errors are not reported on the display, of the water heater.
The Installation-, User- and Service manual, of the water heater, includes a table with
general errors (13.2 "Troubleshooting table for general errors") related to the water

 Displayed errors
Errors are reported on the display of the water heater as follows:
-
Line one: an error code and a brief description. The code consists of a letter and
two digits.
- Line two, three and for: 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 failing into one of two groups:
-
LOCK OUT ERRORS
When the cause has been removed, these errors require a rest with the RESET
button, before the dual service module can resume operation
- BLOCKING ERRORS
These errors disappear automatically once the cause of the error has been
removed, after which the dual service module resumes operation by itself.
The Installation-, User- and Service manual of the water heater includes a table of
errors messages (13.3 "Troubleshooting table for displayed errors") that can appear
