WARNINGS


Any work on electrical appliances must only be carried out by qualified
technicians.

Before servicing an appliance, check the efficiency of the electrical system in the
home using appropriate instruments. For instance, please refer to the
instructions provided/illustrated in the Electrolux Learning Gateway portal
(http://electrolux.edvantage.net).
When the work is finished check that the equipment's safety conditions have
been reinstated, as though it were straight off the assembly line.

If the circuit board has to be handled/replaced, use the ESD kit (Cod. 405 50 63-95/4)
to avoid static electricity from damaging the circuit board, see S.B. No. 599 72 08-09
or consult the course "Electrostatic charges" at the address
(http://electrolux.edvantage.net) on the Electrolux Learning Gateway portal.

This platform is not fitted with an ON/OFF switch. Before you access internal
components, take the plug out of the socket to cut the power supply.

Make resistance measurements, rather than direct voltage and current
measurements.

Warning the sensors located on the display board could be at a potential of
220 Volts.

When replacing the heating element, replace it with one that
has the same characteristics (2 thermal fuses) in order not
to compromise the safety of the appliance. Do not remove/
switch the NTC sensors between heating elements.

Always empty the appliance of all the water before laying it
on its side.

Never place the appliance on its right side (electronic control system side): some
of the water in the detergent dispenser could leak onto the electrical/electronic
components and cause these to burn.

Take care because some of the appliance parts may have sharp edges.

When replacing components, please refer to the code shown in the list of spare
parts relating to the appliance.
