In abnormal conditions the machine may malfunction, as specified below:

MACHINE DOES NOT OPERATE OR OPERATION IS INTERRUPTED

THE MAIN SWITCH IS IN THE ON (1) POSITION,

THE TANK TEMPERATURE IS NOT DISPLAYED.

The plug is not inserted in the sock-

et correctly.

YES

Insert it correctly.

The socket is faulty.

YES

Have it substituted by a qualified

technician.

No electric power in the network or

in the socket.

YES

Check that the disconnecting switches,

all-pole (phase & neutral) isolating switch-

es and residual current operated circuit

breakers (cut-outs) on the electrical sys-
tem, upstream of the socket, are closed.

If not, before closing them, make sure that

no one is carrying out electrical repairs.

A fuse designed to protect the aux-

iliary electrical system has blown.

The power cable is damaged.

YES

Identify and eliminate the cause of the

overload and substitute the blown fuse

with another having the same specifica-

tions and level of protection.

Contact the technical assistance service.

Cut off the electricity supply to the socket

by opening the disconnecting switch up-
stream of it, then disconnect the plug and
contact the Technical assistance services.

DO NOT TOUCH DAMAGED ELECTRIC CA-

BLES BEFORE CUTTING OFF THE ELECTRIC-

ITY SUPPLY!

Contact the Technical assistance
