Electronic Module Description
The electronic module, including the uP, controls various functions and is placed in a protective housing. It is the communication interface between the user and the appliance. It consists of:
The option buttons and the multifunction display LCD.
The programselector with 15 or 21-positions.
The time display and the alarm identification.
The “Start/Pause” button.

Functions:
Taking data of the selected cycle programs through the module.
Water level control (antifoam, overflow level) in the tub; the level is recognized by the analog pressure switch.
Cycle temperature control by a NTC sensor.
Power supply of the heating element.
Power supply of the drive motor (EWM2100) and control of its speed by the tachymetric generator.
Control of the motor control board (EWM2500).
Control of water inlet valves.
Control of drain pump, circulation pump, door lock and DSP (drum self position). In case of a power failure the module saves the just paused cycle.
When the power supply to the appliance is restored again, the cycle starts where the program was paused.

Motor
The motor is directly phase-controlled via
triac from the control electronics.
Relays K2, K3 are responsible for commuting the sense of rotation.
Field switching (if any) is controlled by relay K4.
Speed is monitored by tachometer generator g1 and controlled by control electronics.
Integral overheat protection disconnects the motor from power supply at 115°C

Safety
If the triac for the motor is in short-circuit, or if the tachometer generator is interrupted, 4 trials are executed in intervals of 5 minute each.
After a break of 20 minutes, the fifth and last trial is started. If the motor does not run this time, the programme is aborted.
