1.5 Maintenance

It is strongly recommended to carry out annual maintenance of the boiler and heating system. Please
refer to the "maintenance" section in this manual.
The casing, the control panel and the aesthetic parts of the boiler can be cleaned using a soft and damp
cloth, do not use abrasives or solvents.

1.6 Faults

In the unlikely event of an operating problem, or component failure, the display flashes and a fault
identification code appears.
Listed below are the faults that can be caused by simple, user-detectable problems.
The boiler is equipped with an advanced self-diagnosis system. Should a fault occur with the boiler, the
display will show the fault code. There are some faults that in order to restore operation it requires you
to press RESET
by the operating LEDs (faults from 1 to 26); other faults cause temporary shutdown that are automatically
reset as soon as the value comes back within the boiler's normal working range (faults from 30 to 47).
Example
DISPLAY Fault
Boiler failed to light
Insufficient system pressure
If the problem remains after two attempts at resetting, contact your nearest FERROLI Caresafe.
For further fault codes, refer to section 3.4 "Troubleshooting".
Before calling the FERROLI Caresafe centre, check that the problem is not due to an installation
error or there being no gas or electricity.
(Summer) turns off the heating function but the frost protection remains active.
(Winter) turns on heating, via the room stat and programmer.
