1 PURPOSE OF THIS MANUAL The purpose of this manual is to provide service engineers who are already familiar with the repair procedures for traditional washing machines with information regarding appliances fitted with the EWM 1000 plus electronic control system and produced in Porcia (Italy). The EWM1000 plus electronic control system consists of a main electronic board and one control/display board, “Delta 3”...
4 CONTROL PANEL The configuration of the control panel depends on the following: Type of control/display board Design of the control panel ( max.9 buttons, LEDs) Different configuration of the buttons “FABRICS” Button “TEMPERATURE” Button “SPIN” Button “OPTIONS” Button “OPTIONS” Button “OPTIONS”...
4.2 “Temperature” Button Pushing this button in sequence the temperature is increased or decreased (if a temperature different from that set by the appliance is desired); the relative LED lights. The maximum temperature is 90°C for Cotton, 60°C for Synthetics, 40°C for Delicates, Wool and Hand wash.
4.4 Description of the options The number and type of buttons vary according to the configuration of the model. Possible options according the selected programme OPZIONI 90°C 60°C 50°C COTTON 40°C 30°C Cold 60°C 50°C SYNTHETICS 40°C 30°C Cold MINI PROGRAMME 30°C 40°C DELICATES...

4.5 Description of options 4.5.1 Night cycle Eliminates all spin phases and adds three rinses in COTTON cycles and two rinses in SYNTHETICS cycles. Stops the appliance with water in the tub before the final rinse. Switches off the buzzer (if configured) To drain the water, select a drain or spin cycle.
4.5.10 Sensitive Adds one rinse in the COTTON – SYNTHETIC FABRICS cycles. During the cotton cycles the movements pass from vigorous to normal. Eliminates the intermediate spins except from the last two which are ar reduced speed. 4.5.11 Bleach Ducts water through the bleach compartment at the beginning of the first rinse in COTTON cycles. Pre-wash is possible only if there are three solenoids.
4.5.18 Temperature adjustment Used to select the washing temperature compatibly with the limit temperature for the cycle. Can be used during the cycle selection phase: the temperature can be modified only if the heating phase has not started (in pause mode) 4.5.19 Extra rinse Adds two rinses in the COTTON, SYNTHETICS and DELICATES cycles.
4.8 “START/RESET” Button This button performs two functions: • Cancels the programme: Press the button until the cycle LEDs switch off. The display will show three flashing hyphens. • Selects special programmes: In the programme selection and execution phases, this button can be used to cancel certain phases of the programme so that the appliance effectively performs a special cycle.
4.9 Display (some models) The display shows the following information: Three flashing hyphens, when a programme is cancelled by pressing the SKIP/RESET button. The hyphens will also be displayed when the ON/OFF button is pressed to switch the appliance on, but only if the cycle selected previously has been cancelled.
4.11 ON/OFF Button Press the ON/OFF button to switch the appliance ON. The display shows three flashing hyphens or a flashing zero. Press the same button to switch the appliance OFF. The ON/OFF button is an individual pushbutton, and is not part of the display board.
5 WASHING PROGRAMMES The washing programmes and the functions of each button vary for the different models since they are determined by the configuration of the appliance. 5.1 Possible programmes The washing programmes can be configured: the basic programmes are listed in the table below.

7 TECHNICAL CHARACTERISTICS 7.1 EWM1000 Plus Electronic control The EWM1000 Plus electronic control consists of a main PCB (1) and a control/display board (2). 7.1.1 Functions of the circuit board DISPLAY BOARD µP Buzzer Display LEDs Buttons ELECTRICAL µP SENSORS LOADS MAIN PCB The circuit board receives signals relative to the cycle settings via the control/display board.
7.2 Power supply and programme selection The main board (3) is powered by the interference suppressor (1) and by the closure of the contacts of the main switch (2). The connectors used are J6-2 (neutral) and J10-1 (line). The control/display board (4) is powered at 5V by the main board: the buttons can therefore be used for selection of the programmes and the options.

7.4 Pressure switch Control of the water level is performed by a two or three-level pressure switch which functions as follows: • contact 11-14: anti-boiling safety level • contact 21-24: first level • contact 31-32: anti-overflow safety level (not all models) 7.4.1 Pressure switch settings Full (mm)
7.6 Water fill system The solenoid valves are powered by the PCB via two or three triacs. The status of the pressure switch (empty/full) is detected by two “sensing” lines”. Anti-boiling level 1st level Pre-wash solenoid 5. Wash solenoid 6. Bleach solenoid (certain models only) 7.
7.7 Drain pump 1. PCB 2. Anti-boiling pressure switch 8. Drain pump AB_S Anti-boiling level sensor The PCB powers the drain pump via a triac as follows: for a pre-determined period. until the anti-boiling pressure switch closes on EMPTY, after which the pump is actioned for a brief period or passes to the subsequent phase 7.8 Anti-flooding device 1.
Aqua Control (certain models only) The Aqua Control system is a sensor located in contact with the base frame. The sensor detects water leaks inside the machine (not only during normal operation, but also when the unit is off and plugged in) and starts the drain pump if a leak occurs.
7.10 Heating Anti-boiling pressure switch 1st level pressure switch Heating element NTC temperature sensor Relay AB_S Anti-boiling level sensor L1_S 1st level sensor The heating element is powered by a relay on the main PCB via the contacts of the pressure switch when closed on FULL.
7.11 Motor 1. PCB 2. Motor 3. Anti-boiling/anti-foam pressure switch M = rotor P = motor safety cut-out S = stator T = tachimetric generator AB_S Anti-boiling/anti- foam level sensor 7.12 Power supply to motor The main PCB powers the motor via a triac. The direction of rotation is reversed by switching of the contacts on the two relays (K2-K3), which modify the connection between the rotor and the stator.
7.14 “FUCS” (Fast Unbalance Control System) ( Fast Unbalance Control System) The control procedure for unbalanced loads is performed dynamically, before each spin cycle, as follows: The phase begins at a speed of 55 rpm; the speed can never fall below this threshold, otherwise the check is repeated.

8 DEMO Mode A special cycle has been created for demonstration of the operation of these appliances in retail outlets without connecting the appliance to the water supply. In this way, the salesman can select any programme; after starting the cycle by pressing START, the appliance will perform certain phases only, and will skip those which cannot be performed (water fill, drain, heating).
9 DIAGNOSTICS SYSTEM 9.1 Access to diagnostics system Using a single procedure, it is possible to access to the diagnostics system. After accessing this function, the following operations can be performed: control of the operation of each of the components in the appliance read / cancel the alarms The diagnostics cycles are available only if the communication between the main PCB and the display board is correct;...

9.2.1 Display board diagnostics After entering the diagnostics system, the display board is checked: all LEDs and the display light in sequence (if featured). Pressing the buttons the corresponding LEDs light; the display shows the relative code to the codification of the button and the buzzer sounds. When the “FABRICS”...
10 ALARMS 10.1 User alarm display Control of the alarm system can be configured; according to the model, therefore, some or all of the alarms may be displayed to the user. Normally all the alarms are displayed to the user except for: E61 (insufficient heating during the washing phase), The alarms are active during the execution of the washing programme;...
10.2 Reading the alarm codes In order to read the last alarm code memorized in the EEPROM on the PCB: • Enter diagnostics mode • Press the Fabrics (1) or Temperature (2) button until LED L10 lights 10.2.1 Displaying the alarm The alarm is displayed by a repeated flashing sequence of the two LEDs (0.4 seconds lit, 0.4 seconds off, with an interval of 2.5 seconds between sequences).
10.2.3 Operation of alarms during diagnostics All alarms are enabled during the components diagnostics phase. Moving the selector to pass from one control phase to the other, the appliance exits the alarm condition and performs the selected phase (if the alarm does not occur again).
