Replacing parts (when necessary)

The electrical parts may be accessed by removing the cover (Fig. 7).

Intervene on the power board (Fig. 7, Ref. Z) by disconnecting the cables (Fig. 7, Ref. C,Y and P) and remove

the screws. Intervene on the controlpanel by f irst removing the power board (Fig. 7, Ref.Z).

The display board is secured to the product with 2 screws (Fig. 4, Ref. A). After loosening the screws,

press both the tabs with two ﬁngers (Fig. 4, Ref. B) and remove the support (Fig. 4, Ref. C) from its hous-

ing, moving it towards the centre of the product

After removing the control panel, you can disconnect the connectors of the rod carrying sensors and power

board. Intervene on the rod carrying sensors (Fig. 7, Ref. K) by disconnecting the wires (Fig. 7, Ref. F) from the

control panel and remove it from its seat, taking care not to excessively bend them.

During reassembly, make sure that all components are put back in their original positions.

The product is equipped with four dry heating elements (Fig. 4B, Ref. R) which are not in direct contact

with the water and can therefore be replaced without emptying the appliance. To replace a malfunction-

ing heating element (identiﬁed with a tester), disconnect the relevant Faston connectors (Fig. 4B, Ref. X)

and loosen the screw (Fig. 4B, Ref. V). Remove the damaged heating element and replace it.

To work on the heating elements and anodes, ﬁrst drain the appliance

Remove the bolts

(Fig. 5, Rif. C)

and remove the ﬂanges

(Fig. 5, Rif. F). During reassembly, make sure that

the sensor mounting rods, on which the anodes are mounted, and the heating elements are restored

to their original positions (Figs. 7 and 5).

Make sure that the ﬂange plate with the coloured writing H.E.1 or

H.E.2, is mounted in its position marked by the same writing.

We recommend replacing the f lange gasket (Fig. 6, Ref. Z) every time it is disassembled.

CAUTION! Swapping the heating elements will cause the appliance to malfunction. Work on one element

at a time, and only disassemble the second one after the ﬁrst one has been reinstalled.

Use only original parts from authorized service centres authorized by the manufacturer.

Periodical maintenance

The magnesium anodes (N Fig. 6) must be replaced every two years or the warranty shall be voided (this does

not apply to appliances with stainless steel boilers); however, the anode should be checked every year if the

water is corrosive or chloride rich. To replace them, remove the heating elements and unscrew them from the

brackets.

The bypass pipe (X Fig. 5) is inspected in the event of fault due to its obstruction. To inspect it remove the two

rings (W Fig. 5).

After routine or extraordinary maintenance, recommend ﬁlling its tank with water and draining it completely so

as to remove any residual impurities. Use only original spare parts supplied by the manufacturer’s authorised

service centres

Safety valve

Regularly check that the overpressure device is not jammed or damaged; if it is, remove any scale or replace it.

If the device has a lever or knob, operate it to:

- Drain the appliance, if necessary

- Check its operation from time to time.
