SERVICING
Always turn off the electrical ignition before
proceeding with any servicing operation.
Servicing should be carried out only by
authorised personnel.
11) REPLACING HOT PLATE PARTS
To replace the components fitted inside the hob,
take off the knobs, all the movable parts of the hobs
(trivets, burners and caps) and the screws “V” on
the burners (see fig. 16).
After having carried out the above listed operations,
the replacement of the electrical components and
the taps is possible.
REMARKS: before replacing the taps on the hob
without flame failure device, take off the
microswitches fitted on the taps.
It is advisable to change seal “D” whenever a tap is
replaced to ensure a perfect tightness.
Greasing the taps (see fig. 17 - 18)
If a tap becomes stiff to operate, it must be
immediately greased in compliance with the
following instructions:
- Remove the tap.
- Clean the cone and its housing using a cloth
soaked in solvent.
- Lightly spread the cone with the relevant grease.
- Fit the cone back in place, operate it several times
and then remove it again. Eliminate any excess
grease and check that the gas ducts have not
become clogged.
- Fit all parts back in place, complying with the
demounting order in reverse.
- The tight closure test must be done using a foamy
liquid.
To facilitate the servicing technician’s task, here is a
chart with the types and sections of the powering
cables and the ratings of the electrical components.
