Checks to do:
Get inside diagnostic cycle and fill
in water on
step 5
to make the
pressure switch operating .Turn off
machine and on main board plug
measure between J4-1 and J4-2
an Ohm value (between 5.7 and
6.3 KOhm at 20°C)
Do you read the Ohm value?
-
see pic .16
YES
Measure between J4-1 and body
of the machine and between J4-2
and body of the machine. Do you
measure any dispersion?
-
see pic. 20 -
YES
Unplug connector and measure
directly between NTC sensor
body of the machine . Do you
measure any dispersion? The
machine must have water inside.
-see
pic.31-
YES
Change the NTC sensor and run
again the diagnostic cycle to verify
any further possible alarm.

Measure directly on
the NTC the Ohm
value. Do you read
the right Ohm value?

Change/Check the
cable and run again
the diagnostic cycle
to verify any further
possible alarm.
Change the Main
board and run again
the diagnostic cycle
to verify any further
possible alarm.
