Alarms - Carel compactSteam Mode D'emploi

Note: If no selection is confirmed within 3 s, the software automatically returns to normal operating mode.

5.5 Alarms

In the event of alarms, the red LED flashes, the alarm relay closes, activating the remote signal (if installed) and the alarm code flashes on the
display.
There are two types of alarms: warnings and shutdown alarms. The former can be deleted by pressing the "reset/sel" button for 2 s, while the latter
are displayed until maintenance is performed. Multiple alarms flash in sequence, alternating with the main display.
The table below (Tab. 5.a) shows all the alarm codes, with a description of the problems that cause these and the actions required to restore
normal operation.

ON ON This should never occur in the field; have
the appliance reprogrammed by the
service centre.
ON ON 1) Turn off;
2) Check the connections;
3) Check the cylinder (no bridges of
lime scale between the electrodes);
4) Check that the electrodes are not
shorted.
ON ON Check the conductivity of the supply water
and if necessary replace the cylinder with
the low conductivity version.
Off Off Change cylinder (if necessary).
ON ON 1) Check the water supply and the fill
valve;
2) Check for any leaks from the drain
pump;
3) Make sure the filter on the fill solenoid
valve is not blocked (Fig. 3.g);
4) Check that the steam outlet is not
wor king against excessive backpres
sure, preventing the flow of water
into the cylinder by gravity;
5) Check that the steam outlet hose
is not choked or that there are no
pockets of condensate;
6) Check that the power cables are
connected to the cylinder.
1) Make sure the drain pump is not
ON ON
blocked
2) Check that there are no blockages in
the drain connection.
If the problem persists, perform a number
OFF OFF
of cleaning cycles (see chapter 4.4 "Start-
ing with a new cylinder")
