If the shutdown is repeated frequently, we recommend that you contact an
authorized Technical Assistance Center. For safety reasons, the boiler will in
any case allow a maximum of 5 reset attempts in 15 minutes (by pressing the
RESET key). If the boiler rarely shuts down, this is not a problem.

The boiler is protected from malfunction by the electronic board that
performs certain internal controls, which triggers, if necessary, a
safety locking device. In the event of a blockage, the control panel
display shows a code referring to the type of stop and the cause that
caused the stop.

If the level request is frequent, switch off the boiler, set the external
electrical switch to the OFF position, turn off the gas valve and call a
qualified installer to check for water leaks.
