Instructions to User
Restart oven.
If the causes persist,
error will appear again,
call Service.
Restart oven.
If the causes persist,
error will appear again,
call Service
Check the power supply
is stable (check function-
ality of other units nearby
the oven.
Restart oven, If the
causes persist, error will
appear again, call

If in cooking phase: wait
for the motor to cool
down and restart the
oven after 30 min. If the
problem persists call
Service.
If in cleaning phase: call
Service.

Action for Service*
Check parameter 198
consistency
Ensure all phases are correctly
connected
Refer to Service Actions as for
the FU01 (see "Inverter (MD/
motor drive" section in "Detailed
appliance and components
description/functioning" chapter
of the proper Service manual).
Restart oven, If the causes per-
sist, error will appear again.
Replace inverter (see "Inverter"
section in "Servicing the appli-
ance" chapter of the proper
Service manual).
Check the power supply is stable
(check functionality of other units
nearby the oven.
Restart oven, If the causes per-
sist, error will appear again.
Replace inverter (see "Inverter"
section in "Servicing the appli-
ance" chapter of the proper
Service manual).
Check inverter connector and
ensure outgoing phases are prop-
erly plugged.
Detection mode: T>100℃ on
Inverter sensor
- Check parameter 198
consistency.
- Clean air inlet filter.
- Check for motor fan frictions
(refer to Service actions as for the
FU01).
The self resetting Klixon opens at
130℃
Check for motor fan frictions
(refer to Service actions as for the
FU01)
Restart oven, if the problem per-
sist replace motor.
If the error was detected during a
cleaning cycle, troubleshoot the
water loading circuit. Especially
check the flowmeter cleanness
Ensure the cavity fan does not
interfere with suction wall. In case
fix the interference by ensuring
the proper positioning of the suc-
tion wall.
Replace graphitic rings and clean
the motor shaft prior to reassem-
ble (see "Inverter (MD/motor
drive" section in "Detailed appli-
ance and components
description/functioning" chapter
of the proper Service manual).
Replace inverter (see "Inverter"
section in "Servicing the appli-
ance" chapter of the proper
Service manual).
