Freezing tubes in the boiler supply line in winter time,
bubbles in the water line tubes, broken water filter,
faulty water pump.
Damaged detergent tanks, damaged water tank.
Stop the machine using the red button. Empty the boiler by opening the water drain valve and draining the steam
and rest of water. Open the water tank’s water drain valve in order to empty the water tank according to procedure
described in section “Switch-off procedure” points 10-12.
Open the water drain valves and detergent tanks Fig. 2 element 5 / 6 / 7. Empty the tanks from water and detergent
at temperatures below 0° C.
Replace water filter, replace water pump.
Replace tanks and level probes in fluid tanks.
This indicates that the machine has been left in freezing
conditions at temperature below 0°C without having
emptied the boiler and the water flow line.
This indicates that the machine has been left in freezing
conditions at temperature below 0° C without having
emptied water and detergent tanks.

No pressure in the boiler, or to the contrary: the display
shows pressure, while there is little steam at hose out-
lets; boiler heats up insufficiently and too long.
Perform the boiler descaling procedure using the
VAPOR preparation. Switch off the machine, connect all
cleaning and washing hoses to quick couplings properly.
Empty the boiler and the water tank by opening drain
valves. When the machine is stopped and emptied, un-
screw the coupling that connects the four-terminal net-
work with the copper tube Fig. 2. Using a syringe, inject
some VAPOR into the copper tube. Wait till it starts to
boil, and slowly add small portions in order to thorough-
ly dissolve the mineral deposit inside the tube.
After approx. 20 minutes, re-connect the coupling to
the four-terminal network. Close the boiler drain valve
and the water tank drain valve. Pour approx. 1–2 litres
of VAPOR into the water tank. Start the machine, wait
till the water pump sucks the entire VAPOR in from the
Scaled boiler, scaled steam outlet system and / or clean-
ing / washing hoses.

water tank. As soon as the machine stops and begins to squeal, add water into the tank. Pour the water in until the
machine starts both the burner and the boiler. When the boiler is heated up (16 bar), leave the machine for approx.
5–30 minutes, depending on the system’s scaling degree, in order to completely dissolve the scale. When the scale
dissolving process is completed, flow the steam several times by pressing the trigger at the successive hoses in
order to flush the silicon / Teflon steam line and couplings from any remaining scale. Empty the boiler using the
drain valve completely. Start the machine 2–3 times by filling the boiler, and heating and draining it through the
