Filament issue only?

Hello, we were at the beginning of a sequence when we got this chromatogram. The next two samples look very similar, and then there is no signal. The instrument proceeded and completed the sequence. 

The filament was burnt, but I would like to know if this was the cause or a consequence of the error (MSD: Instrument fault: No emission Current). Could there also be a problem with the HED?
