Symptom problem Solution
The ground
fault circuit
interrupter (GFCI)
triggeredThe
circuit breaker
triggered
When the control board
reboot s the GFCI triggers
The back-cooling fan supplied at 230 V AC has an
electrical leakage, and needs to be replaced.
When the oven is running
a cooking or a cleaning
program the GFCI triggers
Proceed as follow:
Set a cooking program, t = inf, T = 30 °C, v = 4 and run the oven.
■ If the gfCI triggers , it means that at least one motor has an
electrical leakage. Test between the black and red wire of the
motor socket and the body of the oven with the multimeter
set to ohm if there is a ground fault and eventually replace the
damaged motor;
■ If the gfCI does not trigger set T = 260 °C and run the oven.If
the GFCI triggers it means that at least one heating element
has an electrical leakage. Test between the cable harnesses
of each connector of the heating elements (3 turns for each
element) and the ground with the multimeter set to ohm, if
there is a ground fault, eventually replace the damaged heat-
ing element;
If you run the oven at T = 260 °C the GFCI does not trigger, set
STEAM. Maxi to 100 % and run the o ven.
■ If the gfCI triggers , it means that the steam solenoid valve
has an electrical leakage. Test between the cable harnesses of
the solenoid valve and the ground with the multimeter set to
ohm, if there is a ground fault, eventually replace the dam-
aged solenoid valve;
■ If the gfCI does not trigger , set DRY.Maxi to 100 % a nd run
the oven.If the GFCI triggers it means that the DRY.Maxi sole-
noid has an electrical leakage.
Test between the cable harnesses of the DRY.Maxi valve and the
ground with the multimeter set to ohm, if there is a ground fault,
eventually replace the damaged valve;
■ If the gfCI does not trigger , run a cleaning cycle.If the GFCI
triggers immediately it means that one of the water solenoid
valve has an electrical leakage. Test between the cable
harnesses of the solenoid valve and the ground . I f there is a
ground fault with the multimeter set to ohm, replace the
damaged solenoid valve;
■ If the gfCI triggers during the pump loading it means that
the detergent pump has an electrical leakage, and needs to
be replaced.
The circuit
breaker triggered
When the control board
reboots the circuit breaker
triggers
The back-cooling fan supplied at 230 V AC is shorted, therefore
replace back-cooling fan
When the oven is running
a cooking or a washing
program the circuit breaker
triggers
Set a cooking program, t = inf, T = 30 °C, v = 4 and run the oven.
■ If the circuit breaker triggers , it means that at least one mo-
tor is shorted. Test between the black and red wire of the mo-
tor socket if there is electrical continuity with the multimeter
set to ohm and eventually replace the motor with the fault;
■ If the circuit breaker does not trigger set T = 260 °C and run
the oven.
■ If the circuit breaker triggers it means that at least one heat-
ing element is shorted. Test between the cable harness of
the heating element turns if there is electrical continuity with
the multimeter set to ohm, eventually replace the damaged
heating element;
If with T = 260 °C the circuit breaker does not trigger, set
STEAM.Maxi to 100 % and run the o ven.
■
If the circuit breaker triggers
it means that the steam sole-
noid valve is shorted. Test between the cable harnesses of the
solenoid valve if there is electrical continuity with the multim-
eter set to ohm, eventually replace the faulty solenoid valve;
■
If the circuit breaker does not trigger
, set DRY.Maxi to 100 %
and run the oven.
■ If the circuit breaker triggers it means that the DRY.Maxi sole-
noid is shorted. Test between the cable harnesses of the DRY.
Maxi solenoid if there is electrical continuity with the multim-
eter set to ohm, eventually replace the damaged valve;
If the circuit breaker does not trigger, run a cleaning cycle.
■ If the circuit breaker triggers immediately it means that one
of the water solenoid valve is shorted. Test between the cable
harness of the solenoid valve if there is electrical continuity
with the multimeter set to ohm, eventually replace the faulty
solenoid valve;
■ If the circuit breaker triggers during the pump loading it
means that the detergent pump is shorted, therefore replace
the pump.
