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

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.
