Insufficient heating measured by the main board during washing cycle.

SOMETIME THE ALARM CAN BE CAUSED BY LOW SUPPLY VOLTAGE!
Checks to do:
E61
Measure the Ohm value
directly on the heating
element unplugging the
connectors the heating
element is OK?
- see pic.25 -
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 -
Get inside the diagnostic
cycle and fill water up to the
glass to make the pressure
switch operate. In the main
board plugs measure
between connector W2 and
J2-1, you should find the
ohm value of the heating
element. Is the circuit OK?
- see pic. 13 -
Change the heating
element and run again the
diagnostic cycle to verify
any further possible alarm.
Check / change the cables
and repeat diagnostic cycle
to verify any further possible
alarm ( in machines with
display you can read
temperature increasing in
step 6 otherwise run a
normal cycle and feel water
temperature directly on the
door).
Unplug connectors measure
directly on the NTC washing
the Ohm value.
Do you read the right Ohm
value? – see pic 27 -
Change the NTC sensor
and run again the
diagnostic cycle to verify
any further possible alarm.
Change the mechanical
pressure switch and run
again the diagnostic cycle
to verify any further
possible alarm
Measure on the mechanical
pressure switch between
connector 11 and 14 and
between 21 and 24. -DON’T
DISCONNECT THE HOSE-
Do you measure a close
circuit on both measures?
- see pic. 12,14 -
YES
Change the Main board and
run again the diagnostic
cycle to verify any further
possible alarm.
Change/Check the cable
and run again the diagnostic
cycle to verify any further
possible alarm.
If there are burn marks on
electronic board, see page 13.1-2
