1.- Start by checking if the motor and fan spin well and in the proper direction.
If the fan does not rotate at all or if a noise is heard during rotation, it may be obstructed by dirt within the fan housing or the fan itself. It is advisable to clean the fan, the motor housing, and the insulated tube in accordance with the instructions provided in points 3 to 8 of the enclosed cleaning guide.
2.- Proceed to disconnect the chimney from the Roaster, turn on the burner, and press F4 once.
If the pressure (Pa) increases, it suggests that the issue may not be with the roaster, but rather with the chimney. It is advisable to ensure that the chimney is clean and free of obstructions.
If you observe that the chimney is dirty, it is important to clean it thoroughly before connecting to the roaster.
3.- Open the rear door of the machine and ensure that the transparent tubing connected to the SIEMENS device is properly connected and is not damaged or broken. If the transparent tube is loose, it should be reconnected.
Important!
Note that using a mesh in the chimney outlet is not permitted, as this can result in counterpressure issues.
Each roaster needs to have own chimney. Never share chimney, other way the alarms can appear.
If your machine has been recently installed, could you provide us with the length, diameter, and number of elbows of the chimney? Photos or videos would be helpful.
