Measure the NTC probe
between terminals J7-4 and
J7-5 of the main circuit
board connector.
Is the value correct?
(between 5.7 and 6.3 KΩ at
20°C
)
Run the diagnostic cycle
and fill with water up to the
door level to make sure the
heating element is
completely submerged.
Measure between the wiring
connector J6-1/J6-2 and the
appliance body.
