4.6 Boiler Automatic Refill System Failure
(only with the boiler
turned on)
This is a blocking alarm which is signaled by blinking of the
Boiler
(13) light. If the pump
runs for more than 1 minute attempting to refill the boiler without the controller circuit
receiving a boiler full signal, this alarm is triggered.
This alarm can be temporarily cancelled by pressing the
BOILER
(26) button to turn off
the boiler. The S1 can be operated with the steam boiler off until repairs to the boiler
function occur.
Once the reason for the alarm is repaired
– usually a total or partial water line blockage
– it is necessary to unplug the machine and then plug it back in to clear the alarm.
