Phases of the diagnostics systern
After accessing the diagnostics system:
In the first position, the appliance tests the operation of the pushbuttons and the corresponding LEDS. -> Turn
the programme selector knob clockwise to perform the diagnostics test on the various
components and to read the alarm codes.
IMPORTANT !
The alarms remain active during component diagnostics testing. lf an alarm should be displayed, turn
the programme selector to the first position to exit the alarm situation, and then continue the testing
cycle (if the alarm is not repeated).
In order to check for correct operation of the floating switch and the pump (models with canister in the
upper section), the sump is filled with approximately 0.7 litres of water.
For correct control of the conductimetric sensor in a condition of short-circuit (position 7), remove the
cover and create a short-circuit between the two half-shells of the drum or between the front shell and
ground. After entering this phase, the time availabie for creation of the short circuit is just one second;
therefore, prepare the short circuit before turning the programme selector knob to position seven (it is
advisable to do this in a position in which the drum is stationary, then pass quickly to this position). lf
the short circult is not performed correctly, the electronic board will clisplay alarm E32 (sensor
frequency too low). To exit the alarm condition, turn the programme selector knob to the first position.
Open the condenser access panel and check that the switch operates correctly. The buzzer will emit
four "bips" (in different tonalities), repeated every 7 seconds.
