Empty the machine.
Are pressure switch hoses and the air
trap system free? (you can disconnect
the hoses and blow in them to check if
the system is free ) –
see pic.08,a,b
-
NO
NO
NO
YES
YES
Verify the
pressure switch
hoses. Can you
see any leak or
cut in the hoses?
-
see pic. 09, 10
-
(cuts or damages
to the hoses
might be very
difficult to see)
There is an incongruity between the water level measured by the analogic
pressure switch and the mechanical pressure switch “ anti-boil switch 1 “
Checks to do:
(incongruity for more then 60 sec)
Change the
hoses and repeat
completely the
diagnostic cycle
to verify any
further possible
alarm
E33
Clean/change the hoses and/or air trap
system and repeat completely the diagnostic
cycle to verify any further possible fault
Reconnect hoses, start the
diagnostic cycle and go to
step
2
, fill water up to the lower part
of the door and stop machine
(machine could stop after
60sec. timeout, you can reach
the level by selecting
step 1
and again
step 2
) you should
hear the 2 “clicks” made by the
mechanical pressure switch.
On main board measure
between J2-1 and J2-6, you
should find a close circuit. Is
the mechanical pressure switch
OK?
-
see pic.11
-
Change the
mechanical
pressure
switch and
run again the
diagnostic
cycle to verify
any further
possible
alarm
Change the analogic
pressure switch and run
the diagnostic cycle to
verify any further possible
alarm
The fault can be caused by the
washing heating element that loose
his insulation giving strange signal to
the main board. Usually the fault
occurs when the element is hot.
If the alarm still appears change the
main board and get into diagnostic cycle
to verify any further possible alarm
Measure directly
on the pressure
switch -DON’T
DISCONNECT
THE HOSE-
between
connector 11
and 14 do you
measure a close
circuit?
-
see pic.12
-
Change / check
the cable and
verify any further
possible alarm
NO
YES
YES
Drain the water and
select again
step 2
: after
60 sec. does the alarm
appear?
(In the newer models with
display you can read the
increasing of the water
level measured by the
analogic pressure switch)
The fault can be caused by a very
small leak in the pressure hose or air
trap system that can appear after
several time of use
YES
If there are burn marks on
electronic board, see page 13.1-2
NO 1
NO 2
