TROUBLESHOOTING
14.4 E16-CHECK WATER* *only with water kit
Why?
The machine has asked for water inside the
air-break for more than the time set on the
option FILLING WATER TIMEOUT .
Cause of fault
Troubleshooting measure(s)
Switch ON the machine and look if the
time the air-break needs to fill up
completely is too long. If yes, it means
the pressure of the plumb circuit is very
low;
The machine is not filling water at all,
but the LED on the water level board is
ON:

Maybe the overflow system has
been engaged because the
machine has been moved without
draining the
air-break first;

The main inlet water valve is
gone.
The machine is filling water, but once
reached the shorter probe, it keeps
filling all the time. The LED on the water
level board is still ON;

Wrong sensitivity setting;

The air-break probes are dirty;

The connection is compromised;

The water level board got fault.
Raise up the
FILLING WATER
TIMEOUT option.
Follow the procedure at the end of the
paragraph.
Replace it.
Check the sensitivity bridge on the water
level board. Only position 1 should be
activated.
Clean them.
Check the connections from the
air-
break probes to the water level board .
Replace it.
