Meaning :
The filling of the tank is not carried out correctly. The water level does
not reach the low water detection level. (Maximum duration of filling
before alarm: 20 min).
Meaning :
No filling between low level and intermediate level.
Meaning:
No filling between intermediate level and high level.
In this case:
When this message appears, the tank is drained, the general fault contact is activated, and the unit is then stopped.
Possible causes and resolutions:
1. Check water supply. The pressure must be constant and between 2 and 8 bar. If in doubt, install a pressure
regulator set at 2 bar on the supply pipe. Also check the condition of the water inlet valve, the electrical connection
and the condition of fuse F2 (2A). Change the valve and fuse if defective.
2. Blue hose inside the filling cup incorrectly positioned or pinched. Replace the
hose as shown in the picture.
3. Check for proper condensate drainage. Must absolutely be drained, otherwise it will accumulate in the steam
hose, creating water projections and pressure rise in the tank, preventing the unit from being filled.
4.
Verify that the bleed valve is properly closed. A piece of scale can block the valve closure and cause a leak,
preventing proper filling of the unit.
5. Electronic issue. Replace the main board and check that there is no steam or water flow in the electrical
compartment.
