2 TEST PROGRAM E & AT Diagnostic Aid Program > Entry conditions: Before starting the test., it may be necessary to cancel the current cycle, check that the drum is empty and that there is no more water in the tank, and then turn off the "On / Off" key. Press the extreme option keys and set the selector switch to the st on the right of "STOP". > Test : cancellation and restart: It is possible to cancel the current test by a long pressure (") on "Start" and then to restart a test by shortly pressing the same key. > Definite exit from test.: To definitely exit from the test, you have just to release the "On / Off" key or cut off the mains. > Test development: Presentation of E AT aesthetics: Positions of LEDs and keys are different depending on the brand.

10 TEST PROGRAMME E4 Start in test mode: Check that the drum is empty. To start in test mode, starting in P0, put the selector in P and push simultaneously the first three buttons (red arrows) during seg. Because of security reasons, the button combination is deactivated after 0s. EXIT FROM TEST MODE Disconnect the machine Step Selector Display D7 a D0 Test In case of failure, stop the test (see failure code table). - - Test Alternative movements between motor speed: F / xxxx and machine cycles CYCL / xxxxx. Push Start T0 T00 Test interface: Push in a row all the buttons Selector in P Push simultaneously: P Dxx Check the recent failures (movement with START button). Delete failures: Push at the same time: Selector in P T0 See failure code table Activation of the lock (and motor) - door lock and wirings - motor wirings - motor - without water leak in tachymeter - wirings of Posistop Selector in P T0 EV knob for the admission of the water through bleach box Heater activation ( 4º C) - Heating element and wirings - Thermistor and wirings - open main tap - pressure switch and wirings - EV and wirings - anti-leakage system - distributor micro-motor and wirings - door lock and wirings

11 Selector in P T0 Motor with cadence 4/4-50 (with inversion) and draining during 0 s - Motor wirings - Motor - Without water leak in tachymeter - Door lock and wirings Selector in P4 T04 (First do T0 test to fill the tub with water) Recirculation pump (control of the noise) If option Selector in P6 T06 Pump draining command high speed with pump activation. After 5 s, visualization of "YES" mn at máx. - net tension - motor wirings - motor - door lock and wirings - draining pump and wirings - Without water leak in tachymeter - wirings of Posistop Selector in P7 T07 Draining pump command till low level Electrovalve command for water admission through bleach box. [,5 s ON s OFF] * n RMQ:The door is blocked at the beginning of each test and unblocked at the end. In machines higher than.00 rpm, the failure D (motor wiring failure)can be detected in this step. FAILURE DETECTION: draining starts automatically, except in D07 failure. In case of failure in one of the test, if whole checking points are OK, check electronic module. After a failure RESTART THE TEST: The activation of selector allows to start another test. 4
