To optimise washing performance, this appliance offers two different washing systems:
«ctrl»
Washing at a constant motor speed of 2800 RPM.(max. motor speed).
«PW»
Variable-speed (pulse) washing at 1600 > 2800 RPM. This system is controlled by the
electronic control system, which sequentially activates the washing motor at two different
speeds (a minimum and maximum speed) for brief intervals.
The motor speeds for «ctrl» and «PW» can be programmed; for further information, see the table of cycles
for the specific model.

Control of wash pump
The wash pump (PL) is powered by triac TY4 on the main board (connector C3), through the door
interlock switch (IP) and the start button (PU).
The main board controls the speed of the pump motor using the signal from the tachometric
generator (T), connected across connectors E1-E2.
This signal is used for:
Controlling washing systems «ctrl» and «PW»
Controlling the safety systems on the pump motor, and the relative alarms
Controlling dynamic filling
