Pressure switch not enough vacuum - E4000.02

The E4000.02 alarm appears on Rika pellet stoves when the pressure difference between the installation room and the combustion chamber is not sufficient for a new operation.

Resolution

Check the stove for leaks (firebox door, cleaning flap), disturbances in the installation room (extractor hood in operation, closed windows, etc.) and/or the chimney draught.

If the error message cannot be cleared, a technician must be called in.
