3.4.4 

Control of pressure switches closure

The check of position of pressure switch contacts (empty or full) is
detected by the electronic board (14) by means of two “sensing“
lines:

§

 

L1: 1

st

 level (5) pressure switch check

§

 

L2: 2

nd

 level (6) pressure switch check

3.4.5 

Control of washing temperature

The temperature control is carried out by the electronic control via a NTC sensor.
The NTC (16) sensor is connected directly to the timer electronic control (14) to
contacts M9.2-M9.3.

If NTC sensor is in short-circuit or interrupted the heating phase is skipped.
