FAILURE 11: FILL FAILURE
Failure 11 occurs when the water level has not reached its target level in x minutes.
x = Max fill time, a value that can be programmed at the Initialisation Menu.
ATTENTION !!! : The rubber hose must be fixed with a fastener on the electronic water level Sensor.
!
DIAGNOSE:
1. Check if the programmed Max fill time in the
Initialisation menu is acceptable.
2. Check if the external water valves are open
3. Check if the water inlet valves are not
blocked by dirt
4. Check the coil of the water inlet valves
5. Check the drain valve
6. Check if the rubber hose (for measuring the
water level) is well mounted on the
electronic level sensor and on the drain valve
7. Check if the hose on the electronic sensor
is air tight.
8. Check if the hose doesn't contain water
(siphon)
9. Check the continuity of the wiring
10. Check the output relay that powers inlet
valves and the drain valve
11. Check the output relay that powers inlet
valves and the drain valve
FAILURE 12: OVERFILL FAILURE
If the target water level is X units above the target level then failure message 12 will be displayed.
The fault message will not be generated when the user is advancing from a sequence with a high water level
to a sequence with a low water level.
X= "Max. level Overfill", a value that can be programmed at the Initialisation menu.
DIAGNOSE:
1. Check if the water inlet valves are broken
2. Check if the water pressure is not to high
3. Check the output relay that powers the inlet
valve
4. Check the output relay that powers the inlet
valve
In Case of Steam Heating :
If the steam has not enough heating power (too low temperature), the machine will be filled with too much
water at the heating part. This will result in an increased water, energy and supply consumption.
It's strongly recommended that the heating installation works with enough heating power.
A simple solution can also be to reduce the programmed target water level. As less steam will be required,
the normal water level should be reached. In the initialisation menu it is also possible to adjust the alarm level
to avoid the error message. (= not recommended)
FAILURE 13: HEATING FAILURE
If the heater elements are not functioning : message 13 will be displayed.
The message is generated when the temperature is not raising with 3°C in 10 minutes time.

If the water flow is very slow increase the value for the
Max fill time. The default value is 10 minutes.
If the water valves are closed: open the water inlet valves
If the water inlet valves are blocked by dirt: clean the
water inlet valves or replace the water inlet valves
If the coil of the water inlet valve is open: replace the
coil or the complete inlet valve
If the drain valve is defective: replace the drain valve
If the hose is not well mounted: install the rubber hose
properly
If the air hose is not air tight: replace the air tube. With
a fastener, you can make the hose air tight at the level
sensor.
If the air tube contains water: remove the water and fix
the hose so that it doesn't work as a siphon
If the wiring is not continuous: repair the wiring
If the relay receives a command signal but is not
closed, replace the electronic board
If the relay does not receives a command signal,
replace the electronic board
If the water inlet valves are broken: clean or replace
the water inlet valve diaphrams
Lower the water pressure
If the relay stays closed and the relay is broken,
replace the electronic board
If the relay is not broken, but receives a not allowed
signal from the electronic board, replace the electronic
board
