The measured value is NTC
resistance value.
Does it show approx. 4700 OHM under
25
°C temperature? (Picture E1-3)
(There should not be open
circuit / short circuit)
Open the rear cover of the
machine. After removing the
NTC socket on the heater,
measure the NTC value
directly over the NTC.
(Picture E1-4)
No
Replace control card.
Yes
Is there E1 error?
Yes
Is KN2 socket on the control
card attached?
Attach KN2 socket.
(Picture E1-1)
Yes
No
Take out the KN2 socket and
measure the resistance on
the socket between 1st
(green) and 2nd (green) pins
(Picture E1-2)
Does it show approx.
4700 OHM under 25
°C
temperature?
(There should not be open
circuit / short circuit
Replace NTC. Re-attach the
removed sockets into their
places
No
Important Note:
The washing machine makes cold washing
and ends the program before the heater is
activated in NTC open circuit / short circuit
and Heater open circuit conditions, i.e. if
there is E1, E2 or E3 error.
As the value measured on
the control card socket is
wrong, cabling is erroneous;
check it. There should not be
loose or erroneous cable and
socket.
Yes
PICTURE E1-4: NTC resistance to be
measured is 5000 Ohm under 25 degrees
PICTURE E1-2: The socket connected to KN2
connector is removed and NTC resistance is
measured
PICTURE E1-3: The NTC socket on the heater is
removed and NTC resistance is measured
PICTURE E1-1: There are NTC and Level sensor
cables on the KN2 socket.
INFORMATION: NTC resistance
decreases as its temperature
rises. For example, it shows
9500 Ohm
under 10 C and 1700 Ohm
under 50 C. These values are
not erroneous.
