The oven won’t turn on

• Check the correct connection to the electric power supply.
• Check the correct electrical voltage parameters according to the product specifications (check the instruction manual or serial number plate placed on the bottom left side near the control board).
• The electrical connection in case of power supply 380-400 Volt needs to show the three-phases + neutral + grounding and all the phases must be functioning.

The oven turns on but does not reach the temperature
Make sure that once the temperature is set, the cooking cycle has been activated by setting a time, otherwise the cycle does not start (check the instruction manual).

The oven is not producing steam/humidity

• Check the correct connection to the water line.
• Connection to the water line must be open.
• Check the correct water pressure according to the instruction manual.
• Check if there are external filters (not installed on the oven). They must be clean and functioning
• Check the correct setting of the steam function / parameters, at the same time chimneys flap must be in closed position. The flap in open position inhibits steam function even if steam function has been set (check the instruction manual).

Power failure alarm troubleshooting:

• Check the device-power supply connection.

Main consequences:

• If the alarm occurs when the device is turned on or off, after the power supply is restored the device will shut down.
