Causes and corrections
This means that there is no water supply.
The water level does not reach the low water detection level
(the unit cannot produce steam). The fault is trigged on after
some time.
When the fault is displayed, the tank is drained out, the
general fault alert trigged on and the unit stopped.
1. Water pressure - It must be between 1 & 6 bar
and kept as constant as possible. If not, a water
regulator valve must be installed on the supply
line and adjusted at 2 bar.

2. Water softerfer - In case a softener is used,
make sure that the humidifier is still supplied in
water during the regeneration cycles.
4. Steam hose - Make sure that the pitch of the
steam hose is constant and prevent unecessary
ups and downs. The latter create pockets of
condensate that hamper the natural flow of
steam. This generates an undue pressure
inside the tank that prevents the water to flush
in.
3. Blue hose in f illing cup - The blue hose in the filling
cup is missing or mislocated. The blue hose must
hav e one end in the water feed hole and the other in
the middle hole.
The part having the shortest
diameter should be in the center hole and go
down to the level of the black tee (s.a. attached
pictures)
5. Water level detector - Lime deposits clog the water access to the detector. The latter should be
cleaned up together with the water supply union.
6. The draining valve does not close - Either a piece of chalk keeps the valve open (this is the most
frequent occurrence) or the valve has become faulty. In one case, the complete cleaning of the
valve solves the issue and in the other, the valve must be changed.
7. Water level detection - Control water level electrode sensors, X1 connector on the water level
management board and X6 connector on the main board.
8. Electronics - Change the water level management board first. If the fault persists, change the
main board.
