5 Steam generator
5.1 Checking the steam generator
Check the connections for the steam generator for leakage and that the insulation is in-
tact so that no hot surfaces are exposed.
5.2 Checking the function of the steam generator

5.3 Cleaning the steam generator
Cleaning the steam generator as needed
This must only be done by authorized personnel.
Make sure that the machine’s power is switched off before starting work.
Hot water
If the water is hard (above about 6 dH) there is a risk of limescale deposits forming on
the elements of the steam generator. The elements should be checked and cleaned once
or twice a year. The overheat cutout is in the steam generator elements.
• Remove the cover below the ball valve. Empty the steam generator by opening the
ball valve.
• Remove the hose and the check valve.
• Remove the entire steam generator from the pipe system of the machine. Before
the steam generator can be opened, the insulation must be removed and then the
clamping ring.
• Remove any limescale deposits on the elements with limescale remover or me-
chanically (take care, since the elements are welded to the end panel).
• Before re-assembling the steam generator, replace the O-ring between the halves
of the tank. Then t the clamping ring. Tighten carefully to avoid damaging the
O-ring.
• Re-t the insulation and secure it with adhesive tape.
• Fit the cover to the ball valve, making sure that the ball valve is closed.
• Install the steam generator on the pipe system. The gasket between the steam gen-
erator and the pipe system of the machine must be replaced.
• Ret the hose and non-return valve.
• If there is leakage from the check valve, dismantle the check valve and clean the
sealing surfaces in the valve body and on the O-ring. On re-assembly, the locking
screw must be screwed in until it bottoms in the valve body.
If the problems are severe, we recommend increasing the dosing amount (see under item
“7.2 Checking the dosage amount” on page 57 ).
